this is a sony 53xbr35 that's probably 8 or 10 years old. i turned it on last night and saw the pic at the url below. any idea what's wrong and if it's worth fixing? i really wasn't planning on taking the HD plunge quite yet :). thanks!
Just the convergence has let go ..maybe bad solder at bases of the STK,s or Bad STK,s...Either Or..
STK,s are the Output Convergence IC,s..
Thanks very much. I got some more specific info as well, so if anyone else happens to google looking for this info, here is what I was told:
Pull the speaker grill and check the fuses F901 and F902 on the convergence board. If one is open, you have a bad output IC (IC1704 or IC1705). Replace them both. Don't try to adjust anything or you can make things worse.

Probably worth looking into but one other suggestion, simply unplug the set from the 120V for a bit then try it again.
I had a similar model a while back, bought new. One night while watching it, the set made a snap and the picture was quite similar to yours. Tried power cycling a few times, figured it just went bad.
Since it was under warranty (probably was 2 months old at the time), I called to have them look at it. The service appointment was for monday, the set crapped out thursday night. Tried it on and off everyday, same thing.
Monday morning I figured to pull it out into the room and move away the surround sound speakers so the guy could open it up without making a mess of everything.
Did that, unplugged it, hooked it up to an extention cord and made sure the antenna was at least hooked up so he could see the problem and son of a bitch, the set was perfect.
Tried it a few times, on/off, unplug, plug in, worked every time.
Got on the phone to cancel the appointment, they were already on their way.
He showed up, I explained the story to him, he just shrugged his shoulders never touching the set and said "it happens sometimes".
Never did look up the schematic to see a possible cause but no power to the convergence board makes sense (picture looks like a ribbon). Just can't think what could of been "stuck" that the mains pulling could of cured.
Hmm, just checked, not the same, was a kp53v75.
Free to try anyway.

I haven't done anything yet, this weekend I'm going to open the TV and verify the problem. Monday I'll need to price the parts and then I'll need to see if I can find someone that will replace the parts for a reasonable amount of $$$. If that doesn't make financial sense, I guess I'll be selling off my Atari Quantum to pay for a new TV.
well if you figure it all out and get a price range could you let me know? thanks again man!

don't sell the quantum! tv's come and go.. almost expendible. the quantum... well. .you already know.
k.
see
Yeah.... I already know :). Took me years to find one, but it's been sitting in my friend's basement now for many more years. I love it, there are probably only a couple hundred left in existance, but I keep asking myself what good does it do me. Besides, video game prices are dropping and will probably never return. Between MAME, the .COM bust and most of the generation that grew up with the game now with families as a priority, it will probably never appreciate again. I saw they were selling for as much as $4500 around '01 and '02, now I'd be lucky to get $2500. Tough call...................
Just an update, in my case the parts I need are the STK4278L which I ordered two of for $21.59 including shipping from
So hopefully after these and 1 fuse, I'll be back in business. Next step is either braving the soldering myself or finding someplace that can do it. Not sure what sort of business actually solders anymore, they all seem to just like replacing boards at best.
Dont forget to check the return resistors just to the left of those 4278,s
hey man, just an update, my tv was off for about 2 weeks straight, and i just turned it off, and i'll be damned, the thing works perfect! i guess it just needed some rest? how's yours been?

i just received the STKs, however i talked to a local shop who was actually familiar with my issue (they asked me if it was an XBR when they heard the symptoms). they told me that there are likely a couple of other problems, namely an IC on the left side of the board as well. they also suggested i talk to a local company they get all their parts from who has fixed dozens of these things. i've been trying to reach them but they haven't been answering the phone. perhaps they went on vacation last week without an answering machine, i dunno, hopefully they're around tomorrow.
nevermind, about an hour into watching it, it messed back up again ;( it was pretty rad while it lasted, now i need to actually get it fixed ahahah

turns out the place i was told to call went out of business, so i just dropped the board off at the shop that recommended the other shop along with the STKs. once it's fixed i'll post the components that needed replacing.
well the board is back and so far so good. my wife picked it up so i need to call tomorrow to find out if anything else was bad. the work order says something about some additional soldering. only thing im not happy about is he told my wife he quoted me $100, so that's the charge, when in reality he told me 'it shouldn't cost more than $100 depending on what i find wrong with it'. on the other hand, labor these days is expensive and it's working, so as long as it stays working i should count myself lucky it was only $125ish (with the new STKs) and not $1000+ for a new TV. On the other, other hand I was almost hoping it wasn't salvagable and had my eyes on a Panasonic AE700U front projector :).
