I thought I answered that one? MMM Ok Mary, your set has a vertical problem it sounds like. it should still be a good TV set as a vertical repair should not run you over 300 bucks. Good Luck and please let us know how you made out.
My Mom has an older Zenith System 3 color TV SR273BRK it also has PIP
but is not used; it is hooked up for cable input w/o a box. Color
has been going out a bit and people are starting to look like
martians:) I was wondering if there is anything we can do
to remedy this situation. I tried adjustion the color tint
thru the menu but it only helped for a while. The reds don't look red
anymore. Any help would be great. thanks.
Larry, the shadow I mentioned is a black area that blocks out the picture. its not always there however it is there most of the time. If you look at the screen, at about 1/2 way down on the left to the bottom it is black and it radiats out from there across to the right getting narrower as it goes. I'm looking at it right now and the whole bottom is black, then the picture changes and the whole picture is visable. It changes again and just the left corner is black, That is baxically what it does all the time. Got a clue what is causing is. Any help would be wonderful. Thanks, swiftjd
Swift, by the description, it sounds like you have leaky capacitors in the sweep power supply that supplys the screen and drive voltages to the Picture tube. If you have the experience troubleshooting solid state circuits using an ESR type capacitor meter, you should be able to find what cap. is bad. But if you do not, I recommend you seek out a trained tech on these sets to assist you with this repair. im sorry to say this is not a quicky fix , or an easy one. Good Luck.
455 rocket, you will need a cross hatch generator or a DVD with a cross hatch on the disc on puse to adjust the convergence. Yes it could take 5 minutes and it could take hours. Been there done that. go to PTScorp.com. Find the tele number there on the site as i know there is one. call them, and tell them thew number of the convergence board thatis in that TV set, and how much to rebuild.
hi,i am having random/periodic blackouts from watching or playing HD programs,from both my HD-tivo and ps3.
I got an older hitachi model 53sdx89b.it has only 1 cmponent input on back for hi-def.every since i been getting hi-def programs to watch i get a random/periodic blackouts, from both my hd-tivo and ps3.
Is my tv dying or is just wanting to get repaired,or could it be since my tv only has component input,and HD doesnt like component?
my tv only seems to be blacking out only HD signals, other non-HD programs i watch never blacks out.I wanna know why this happens, I am beginning to think that since my tv only has component input it cant handle the hd-signal its getting, these black outs are very annoying.
Hello all. Hopefully someone can help me with my problem. I have a 36" Panasonic HDTV Tau Flatscreen. The other day the TV would not power back on. When the power button is pressed, I can hear the click, the monitor begins to turn on, then another click and about 5 beeps with the power light flashing. Does this seem like a serious problem? Or can it be repaired. If it can be repaired is it something a novice can do? Or will I have to call in a repair person?
Ok, this sounds like there is a short in the set as the set does try to switch on and detects the short and shuts down. That noise is the straining loaded down power supply trying to keep up the voltage but cannot. This could be a shorted horizontal output transistor almost any part in the sweep supply. My advice would be that if you have no TV repair experience, seek out a local servicer, as there are no user replaceable aprts inside this set, and it certainly does not sound like a fix that a novice can or attempt to do. Good Luck, and let us know how you made out.
My Zenith z56z83: It appears several resisters are bad and affected the IC's. The service recommends having the whole board rebiult from LG, 181.00. Now, what is the probability that I will have other problems? Can the IC's burn up agian as soon as I put the board in. Is there anything else that may be wrong prior to this, that will require more service? Any idea what the convergence sequence is? Any schematics available? Am I taking a big gamble with this? What is the probability I put the board in and converge it and don't have any other problems? Thanks for any help.
Thank you for your help. Had the repair guy come in today. He said it was repairable but will most likely short out again within a month or two so it wasn't worth fixing. Sadly, I will be going TV hunting this weekend.
The TV is an AKAI Plasma, Model # PDP4225M the picture is great when you first turn on of about 20 minutes then the color fades away it seems like it's trying to lock in the right frequency because the picture look grainy then it shift to a clean pix but no color and stays in B/W is there any tech tip that you can give me?
Hey Larry, just wanted to let you know what we decided on our tv that had the convergance problem, we had it repaired and now the yv looks really great, like new, really! obviously needed to be cleaned inside and had another problem iwht the power board inside. anyway, even at the 500.00 cost of repair we really are glad to have had it fixed and thank you sooo much for all of your help!
I am having a problem with an older model of JVC it has a yellowish tint to it. I dont think it has anything to do with the tint or the color on it maybe something wrong inside? Please advise thank you.
It is the B&W picture, no color. If you do not have a good grey scale, the picture will look lousy. You are going to need to most likely have the set adjusted for proper grey scale, if you do not know what it is. A TV set IS NOT a place to be experimenting around inside of. If the greyscale cannot be adjusted properly, most likely the picture tube is bad or one of the RGB drives is weak or needs repair. This is not a job for the handiman or a novice. Good Luck
I have a RCA console TV Model #G26359HP.I can tap the tuner and I get a picture,it will play for a while then it goes,off,like no signal from cable.Tap again back working.Could this be a loose connection at the tuner to the board?.I think I have a part number,#196040,If so would this be something I could do.Thanks a lot Marvin
Starvinmarvin, the problem is a bad connection on the printed circuit board or a bad connection inside the tuner assmbly. This tuner is a tricky thing to repair if that is where your problem lies. If you have any experience solderinig on solidstate printed circuit boards, you should be able to fand a bad connection or change out the tuner. One is available at http://www.partstore.com for about 65 bucks plus shipping. A repair shop will probibly charge you a couple of hundred bucks to replace the tuner. if you have no solid state repair experience, I would highly advise you to seek out a pro to assist you in the repair of this TV set. There is just too much high voltage inside these tV's, even when they are unplugged, for someone to be experimenting around inside this TV. Good Luck, and let us know how this repair turns out.
I have one hdmi port on my philips plasma. When I used the hdmi input i would often have to turn the tv off and on a couple times to make it work correctly. I investigated and had a bent prong. Of course I tried to straighten it only succeeding in breaking it off. can this be repaired easily or at all.
Did the pin break off of the TV port or the HDMI cable? if it broke off the TV port, the entire connector will have to be unsoldered and a new connector will need to be installed. if it is the cable, replace the cable as it is not worth the time or effort replacing a cable connector. If you do not have any solid state repair, or printed circuit, or soldering ability, please play it safe and call in a trained tech to assist you with this repair.
Hope you can help as this is becoming a real pain.
I bought a SAMSUNG PS42Q7HD plasma about 2 months ago. The TV is great in normal 'live' mode ... BUT....
When I use any recorded media via an EXT connection i.e. both scart connections in the rear of the TV, the screen intermittently flashes black and white throughout the program. It can work fine for a few minutes and then it starts flashing for a few seconds or more and is almost impossible to watch during that time.
I am talking about my VCR, DVD and also my SKY+ plus box (UK satellite)where I record and replay most of the programs I want to watch.
I have done the obvious and checked physical connections, swapped connections, and even checked all these external devices by attaching to another TV where I dont get the problem - so by process of trial and elimination this indicates 100% it is specific to this TV and not the attached devices.
I have also checked the TV user manual etc. but nothing to assist me resolve this.
Please can you advise if this is a known 'fault', if it can be resolved or if it seems likely that either the TV or the rear connections sound 'mechanically' faulty and the TV needs replaced.
If the set is only a couple of months old, it should still be under the factory warranty. What you need to do is disconnect everything and ONLY connect up one device via the scart leads like a DVD player and make sure it is the TV set. It could be a possible problem with one of the other devices depening on how you are connecting everything up. If this is the TV set, this repair will most likely involve the replacement of the scaler board or the main board and those are not cheap. Good Luck and keep us informed of how this turns out for you.

This question is about my Zenith 60" TV again-model RZ56Z83. Thanks for
the prior information Larry Dillon. It seems some resistors are burnt on the
convergence board, five or so. I don't know what it will cost to repair, but
you had mentioned an exchange for a rebuilt one, who does this and for
the cheapest, as I don't to spend a lot of money repairing this thing.
Question two: Once I reinstall this baord, how do I go about recalibrating
the colors? Any manuals available? Can I use the remote? A service
guy told me it could take four hours or five minutes. He said you may need
to take off the front panel off the TV and adjust it there, Is this true?
I was able to get the screen up on the TV prior to coordinate the lines to
the white convergence line (the colored lines didn't move or should I say I
couldn't adjust them). Could I do this from the remote? Also, what other
things do I have to worry about. Is there any other boards afffected by not
converging things correctly and can that burn out the board I just replaced?
I hear conflicting things. Any help will be grreatly appreciated. Thanks

Thanks Larry D. and Swift jd for the quik response and info. I paid 100.00
dollars for the TV and two nice Sony VHS players, of course I use DVD. So,
what do you think about repair? Cost wise what would the damage be.
I had to lug this 400 pound mama up 20 stairs from the guys house. Any
ball park figure? 250-400? I have some basic electricity, but mostly in
automobiles, I'm not a TV guy. Boy, you could really dig yourself in a
hole. So, if you find the leaky 3mile island capacitor from the sweep power
supply and replace it, what is the process of getting this set up and
running.
The things we do for our kids. Could the leaky capsitor do the same thing
again to the new replace board? What could I do to get by with the
basics? Any directions how to get schematics for this TV? I don't even
know where the sweep power supply is. Thanks again for all your help.

soto345, is this a picture tube set, or a LCD or Plasma?
Ok, this sounds like there is a short in the set as the set does try to switch on and detects the short and shuts down.

Its almost like you can see the colors but with a layer of yellow across the whole screen. I am not sure what you mean by greyscale.
It is the B&W picture, no color. If you do not have a good grey scale, the picture will look lousy.
