JohnnySmoke, I can't take

JohnnySmoke, I can't take credit for the hex wrench idea, I just remembered it from someone else's previous post.

Chip, look here for sony convergence article by zapdbf amd Larry.

I'm back. On my Sony KP

I'm back. On my Sony KP-65WS500. I replaced STKs and pico fuses on the G board. Everything looked like it was going well. Just needed to make some convergence adjustments. First did Red on green and it was fine. When I went to do the Blue on Green, I cannot move the blue at all. I can adjust red and green, but not blue. Any suggestions?

Hi, there

Hi, there

Did anyone buys stk392-570 IC chips from this online dealer? Are they reliable and made from Sanyo originally? Also 5A pico fuses are also at good prices?

Thanks for information.

Hi, there,

Hi, there,

One more questions. How many 5A pico fuses do I need to purchase online? I have not check yet and I do not know how many burned.

Thanks.

find in the manual which convergence resistors are related to the stk blue and check those

Did anyone find out how many fuses there are to be replaced?

I've done 3 of these repairs and haven't had to replace any fuses.

Thanks for the reply.  I will be taking the parts to someone else to solder so should I just replace them anyways to be safe and save time (and possibly money)?  I don't really have the soldering experience so I don't want to mess it up...

I don't guess it would hurt

I don't guess it would hurt to change them, but that seems like a lot of work when a simple ohm's meter ( $3 bucks at harbor freight ) test would tell you if you need to or not.

Larry,

Larry,
This site has been invaluable in working through convergence issues. I have the bowtie effect on a Sony KP-46WT510. Have pulled both STK chips from the D board and found one pico fuse out on the G board and preparing for replacement.

a) Any benefit in stepping up to a STK392-570 or should I stay with STK392-560?
b) Is it typical for just one pico fuxe to need replacement?
c) Can you send a copy of the service manual to me for runing the final adjustments.

Thanks for all your help!
Scott

Your early coments of the difficulty of installing the convergance IC's is overly stated and misleading. I have no soldering skills, only played around with a board once and did not buy any special tools or soldering iron other than the old $4.00 job I purchased from radio shack 20 years ago, and I was able to replace the SK392560 IC's with little difficulty. Why don't you save your sorry-assed, depressed advice and place it somewhere else. For others trying to do the IC replacement... listen to good advice from people like Larry Dillon and others on this site.

I have the same model

I have the same model television and have been having problems with the television shutting back down after powered on followed by blinking standby light on the front. I had a best buy technician come out and diagnose the problem. He told me that the d-board part #A-1302-180-A needed to be replaced, so I called PTS and they told me I can extract the board and send it off for rebuilding. I have almost completely extracted the board but there is one red wire that is connected to what looks like a grey transformer of some type and I can't figure out how to disconnect it so I can completely extract it and send it off for repair. Can anyone please help me out with this. I don't want to cut and resolder the wire unless I won't hurt any parts.

You really need to read more

You really need to read more of this thread, but you push and twist it to the left, and disconnect from the TV side.

Before you ship your board out, you should at least skim over this thread. The answer I just gave you, along with a few horror stories about shipping these boards.

btw.. If you can take it out, then you can fix it. Unlike what my big fan above "said I said"... It's not hard, probably not as hard as taking the board out.

Larry,

Larry,

I get a question to ask about Sony KP-51WS510. I found that there are two 5A pico fuse on G board and six 3.15A pico fuse under heat sink on D board. Is that correct for that model? If 3.15A pico fuse is bad, can I use 5A pico fuse to replace 3.15A pico fuse or I need to use the exact model of pico fuse as a replacement? I use the analog multimeter to test those eight pico fuses(5A and 3.15A). The OHM shows all zero. It looks like they are good? Right? Thanks so advice.

Kindly, John

Manthelm I did as you said

Manthelm I did as you said and tried pushing in and turning counterclockwise but no dice. Can you send me those manuals you spoke of earlier in the thread so that I can get a better picture of what exactly I am doing so I don't mess anything up? I would greatly appreciate it my email is [email protected]
Thanks again

Sometimes they can be a pain, but slide the boot back and out of the way, push in ( maybe shake a bit) twist left and pull.

good luck

your problem may be simmilar to mine.  when you push in the boot, make sure you push in the cable also at the same time.  try moving the cable in a circular motion a few times before you attempt to take it out.  sometimes heat causes them to stick a bit.

Thanks man I got the manuals

Thanks man I got the manuals and got the wire loose I just wasn't pulling hard enough because I was afraid I would mess something up. So thats it huh? Now I just send it off with the transistor and two red wires still connected and wait for repair, and just re-install am I correct? Thanks so much man you've been a great help

Could someone send me the service manual for the KP-46WT500? This is a very helpful website. I almost lost hope for fixing my tv. email:[email protected]

Good Job, But I can't stress

Good Job, But I can't stress enough the chance you're taking sending that board out to be fixed. I sent my first one out, via UPS, packed as tight as I could get it. The company never called, and when I called them, they said it arrived cracked ( therefore ruined. UPS denied the claim and I never saw that "cracked" D board again, even though they "shipped it back to me".

Bottom line is, if you must ship it ( try to find someone local) read through this thread about packing. I think I wrote something about it, if I didn't let me know and I'll give you some tips.

tip 1: No Peanuts....

As far as I know, that's the only one we have. But their all close enough. It'll get you into the service mode on Sony, and the "D boards" and IC's are pretty much the same on the projection type TV's I've seen.
