Larry,

Larry,

Thanks for the advice. I haven't thrown it out yet. Maybe I'll get the repair kit and see what I can do myself. If mess it up, and don't shock myself, then I can take it to the curb...!!!

The problem is with the new TV (replaced same day with some deal-making with Microcenter!) mounting on wall, snaking cable to room behind to make a neater setup, putting in-wall speakers, even with help I've got quite a few "challenges" these days... not to mention the day job!

Just wanted to thank everyone

Just wanted to thank everyone here for all the info, My KP-46Wt500 went out of convergence a few weeks ago, I replaced both IC's and one pico fuse on the G board, now it works like new. Thanks again.

I have a KP46WT500 and

I have a KP46WT500 and replaced the red tub myself cause the old one put lines across my screen. What is the easiest way to focus that tube without having to do turn after turn and getting electricuted cause I have to do it while the tv is on???

Well, I just repaired a

Well, I just repaired a Magnavox 37MF321D LCD HD TV that I picked up for free and am hooked on trying to fix stuff like this. I found a KP-46WT500 for sale for 40 bucks OBO who had replaced the convergence ICs but hadn't touched the fuses. I plan on picking it up and repairing it, but I was hoping someone could please email me the repair manual to [email protected] I'm sure I might have a couple other questions later on, but I like to learn as much as possible to start. Thanks, Christian

Larry,

Larry,

I had previously posted the converge issue on my KDP-65WS550.  I have set the TV to service mode to test the components and I got all "0" on every aspect of the test. I performed this by pressing display - 5 - volume "-' - Power.  In addition I performed the test reset which is done by performing the previous steps and then pressing 8 - enter.

The test did not identify a problem, the reset did not fix/identify the problem.  I have re-attempted in doing flash focus, but my converge is still off. Should I look into replacing the recommended components, or do you know of another test that I can perform.  Your advice would be much appreciated.

 Problem:  My display shows the color blue not ligned up with any other color, the right side and left side are by far the worst.

Jose.

Screen looks 3D Colors don't

Screen looks 3D Colors don't line up One or more colors can't be adjusted when using the convergence menu. Screen is bowed or warped. Here is a quick test.... Using your original remote go-to the TV settings then go to the convergence section. Try to adjust the red and then the blue convergence. You should be able to move them up, down, left, and right. If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem. Solution #1 you need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for most models. If you don't see kits for your set send them a quick note under the contact us button please, you will get an answer within 24 hours or so.(excluding holidays Good Luck

Your TV most likely has one of two possible problems.

ANY INPUT FROM ANYBODY WOULD

ANY INPUT FROM ANYBODY WOULD BE GREATLY APPRECIATED!! PLEASE!! I'm having convergence problems with my Sony kp-65ws510 and I can't figure out what else to do! So far, my brother (an electrician) has changed out BOTH ic's (STK392-560) AND the burnt pico fuse (3.15A 125V) on the D board and still no luck. Still have the 3D look. He's rechecked the pico fuses and they're fine. He suggested that I might need to buy an entire D board but I wanted to get some more input before I dumped any more money into this! When he tried to adjust the screen, he said the red and green partially move but the blue doesn't move at all. He also wanted to know if anybody knew where I could get the STANDARD data line info, not the adjustable data line info. Any help would be tremondously appreciated! I thank you very much in advance for your help!

no such thing for this set

no such thing for this set there is no way of programming data to this set there should be a service manual available here on the technicians corner under the resources tab on the home page.

Hi Larry! First off, let me

Hi Larry! First off, let me thank you big time for replying to this on Christmas! In all honesty, I was hoping you'd be the one to respond! My brother is leaning on the side of me needing new convergence chips thinking the ones I bought were bad. They were the least expensive ones I could find and I'm thinking about buying new ones from another company. Could that be the problem or do you have any other suggestions? Thanks again for your help. I really do appreciate it! Have a Merry Christmas and a safe and Happy New Year!

The best advice I can tell

The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! The kit comes with original Sanyo STK ICÂ’S , not those cheap aftermarket or china made ICÂ’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases,

I am in the midst of repairing the convergence ICs. How do I remove the red HV wires from the D board. Service manual seems to indicate to rotate 90deg CCW but I'm not having any luck.

I just tilted the board up without removing the HV wire, I had a little trouble getting the snap down connectors from the side off (one of them cracked but it was fine).

I got it.  I removed both wires from the other ends instead of from the D board.  The smaller HV wire was easily removed from the board in the front of the TV and the larger HV wire was removed from the distribution block.  The trick to removing the larger HV wire was to push in before turning CCW.  I replaced the ICs and the picture is back to normal.  I decided to replace the 560 ICs with 570 ICs since I read where they may be a little more robust to the high temps.  I did not have to replace any resistors or pico fuses. Thanks for the info on this board.  It was very useful in diagnosing the problem and making the repair.

Did you check the 5A pico fuses on the G board?

I'm pretty positive my brother checked those also as I told him I noticed that other people metioned that could be the problem. I'm not sure though. I could kick myself because I didn't realize Larry responded to my e-mail on Christmas but I didn't notice it until a few days ago! I would've ordered the repair kit. Since then, I've talked with a repair tech in town and he gave me an 800 number to have my "D" board fixed and it happened to be linked with techlore (I googled the 800# and it gave me techlore.com)! I've sent the board to be repaired to PTS electronics! The tech did mention if I had my "D" board fixed that it should run ok. Of course he couldn't guarantee and I don't blame him! Can you tell me if that's true? He also mentioned that he wouldn't touch it due to the fact that we've tried to adjust all three colors individually. By having the board fixed/referbished, will I still have to deal with that or will I just auto adjust then fine tune it? I genuinely do appreciate your help Mark! You and Larry have been a Godsend for helping me with this. Thank you very much again.

Larry Dillon
i guess you did not read

i guess you did not read enough of these threads first as NEVER EVER try to make any adjustments before repairing the board!!
Larry Dillon NOW EVEN WITH a brand new board the adjustments will need lots and lots of adjustment and lots of patients as well

Larry Dillon
also i hope u used the

also i hope u used the original Sony/Sanyo ic's!!??

Larry Dillon I know you get a

Larry Dillon I know you get a lot of requests for this but I was wondering if I could get a copy of the service manual for the kp-46wt500 model. I have been reading through out this forum and purchased the ic chips for my TV. I have removed the old ones and installed the new ones. The TV is worse than it ever was. One of the solder spots on the board for the pin had no copper left to solder to so I bridged the solder from the pin to were I thought that pin would go to but not quite sure. would love to have a pic or diagram to go off of. My e-mail is [email protected]. This forum is great I would not have tackled this if I didn't come across this forum........

Larry Dillon
did you first off get the

did you first off get the original Sony/Sanyo IC's as if you did not the set will be a real pain to adjust. but if you did GREAT!!! the service manual is available from the technicians corner off the home page under the resources tab.

I have a Sony KP-46wt500 that is suffering from the blue screen of death. I get a picture for a few seconds then the screen changes to solid blue for a few seconds then the TV shuts down. The focus light blinks 8 times over and over. I have already paid over $400 last year to have the TV repaired so this time I would like to either do it myself, or convince myself that it's time to upgrade to a plasma or LCD unit. Could you please send me the manual for this TV and any tips you may have.

Thanks

That symptom sounds like you

That symptom sounds like you have a bad blue picture tube?

I found the manual on the homepage, it seams that the 8 blinks is related to a high voltage problem on the D board. I'll have to take a look in there and see if their is any obvious problem.

Larry Dillon
Yes that has been a bad fly

Yes that has been a bad fly back, focus block, or a bad picture tube can cause this 8 blink issue.

Got the Referb'd D board from PTS Corp, After we put it in the Auto Focus STILL wouldn't get the picture to work right. This time around, NONE of the grid colors move! Also, when my brother tried to adjust the grids to the specs in the manual, the manual states +/- 1000 and the numbers on the screen only go up to 200-ish. Is there another "code" to go into to get to the higher numbers? Any last suggestions before I pitch it or try to gut it and sell the parts? Thanks again for all of your help. I'm really bummed my TV is fried...

Hey Larry, thanks for your

Hey Larry, thanks for your help with my convergence issue on my KDP-65WS550 Sony TV. I was able to order the IC's and Pico fuse from TVRepairkits.com. I only had to use two pico fuses, all my convergence fuses seemed ok, i didn't take any of them out, but they didn't looked burned or bad. I also replaced the two IC's went from a SDK392-560 to a 570. I did notice that I had to put the TV in service mode and manually adjust the green, red and blue colors. I know this wasn't something that was mentioned to do, but on mine I had to do it. The picture looks good now, but it seems that it doesn't have that GREAT image that I remember having. Could I still be missing something, or is this as good as it's going to get?

Larry Dillon
not really sure if you missed

not really sure if you missed something? did you clean off the mirror and the three tube lens?? if not you really should
Larry

jr5050jr
ok, i didn't clean them. It

ok, i didn't clean them. It just seemed odd that I had to manually adjust my flash focus. I figured since I'm going with higher IC's that the TV wouldn't adjust by just replacing them. So i performed the manual adjustment. On my G board, my TV model didn't have any Pico fuses so I didn't do anything on that one, only my D board. I will clean out the lense and the mirror to see if that makes a difference, Is there a recommended way of doing this?

Again thank you Larry, you've been very helpful.

Jose.
