Red Convergence on Sony KP-53V80 falling!

Parts could run from $25-$100 depending if they are original parts or Chinese junk parts. You have a convergence correction circuit failure. IC1502 is bad, that controls the Red and 1/2 of the Green. You should have the other one replaced at the same time. Part # STK392-150, There also may be an open or changed value resistor, 2.2 Ohms that will need changing. It will be visible very near the defective IC.

Do not use junk replacement parts my friend! And DO NOT just replace one IC! r You eplace both at once or a few months down the road you will be doing the same thing .    Use only the ORIGINAL replacements as like I stated if you dont you will be sorry.  Also do not forget to use plenty of heat sink grease on the back of the IC's when replaceing them as if you do not, you will be doing the same thing in the next few months or maybe even weeks!  Also make sure the IC's are mounted tight up against the metal heat sink.  Good Luck and if you need any more assistance please dont hesitate to ask.  And please let us know how you made out as maybe your experieances will help another.

Patrick,  smart move!   Its a good Idea that if you have no electronic or printed circuit board experience, to leave it to the pros.  After all would you want to try to disable a bomb one your own to see if you could do it?  I think not.  Good Luck and let us know how you made out. 

I do have same issue with my Sony KP-53V80. I am trying to remove the board for reworking, but there are two red cables that I don't know how to unplug out from the board. Could someone can help me? Oh, I have an image about the location but I don't know how to post the image to this comment area.

Hi Larry,

   I have sent the images to [email protected] .

Thanks!

Stan

If I'm not mistaking, thoses plugs unplug or you twist them 90 degrees and pull them out at the High Voltage distribution block at the other ends of the wires.

I'm having the same problem with a sony KP-51HW40. Where can I get  these? Also would you know the part #'s?

Thanks 

Last time, I posted how to unplug the high voltage cables from the board. And Larry said twist them 90 degrees and pull them out. It is right, but they are not my pointed position as the image. You need unplug them from the other ends. Thanks Larry.

My TV is fixed without problem and just replaced two IC. Part # STK392-150. I want to mention there are high voltage cables, so you have to be carefully. The image always uploads fail, or someone can help to upload  and post it here.

Great News Stan!  Glad to hear we were able to help you, as this is what we are here for.  SPREAD the news to your  buds.  We also help with alot of other things as well.  Come again.

The IC's for the model tv I posted. I'm having the same problem except I dont have the 3D look. I just have the the blue and red lines that show up. They are across the whole screen though. You can really see them on a dark screen.

Any help would be great.

Thanks

oh OK.  They are STK392-150  Plus I hope you have a small multimeter and know how to use it, as there are small feedback resistors, 1.2 to 2.2 ohm resistors that go bad sometimes nwhen these parts go bad also.  Good Luck, and let us know how you made out.

Blitz, ask why the other part for 101.18 is not on the online data base for sears parts and what is it?

Larry

Thanks. I do have a multimeter and know how to use it. I will let you all know how things turn out.

Thanks 

Hey... i am just curious, the part STK392-150, do i get two of those for my tv? or is that just one of the ic's that i need? If it's only one of the ones i need, what is the part number for the other one? my tv is a 42 inch sony kp 43t75. also, i looked up the part number on google and it gave me a price of 6.99 on some sites. do you reccommend that i use that website?

Unfortunately I'm having the same problem with my TV and itÂ’s actually the second time it happens. The first time was about 18 months ago, but back then I had Warranty on the TV and based on the receipt the cost was $44.00 for two CONVERGENCE CORRECTION CKT plus $150.00 for labor, but luckily I had warranty to cover this cost. Now the warranty on the TV as expired and I have to try to fix this issue on my own.

My questions is do I need to only replace the two CONVERGENCE CORRECTION CKT parts or is there anything else I need to replace?

try to replace the convergence iC's first then if that does not work you will need to check the pico fuses around th IC's and the two pico's on the G board.

The TV I have is actually a Sony KP-51WS510 with the convergence problem.  And I just bought the two STK392-560 Convergence IC.  But can you please send me a copy of the service manual at [email protected] or at [email protected].

 Also before I change the IC’s are there any additional precautions I need to take before I attempt to change these parts?

Hi, there: I had similar problem with KP-53V80. The flash focus button seems working. The TV aligns fine for the cross-bar but then showed double pictures. In addition, some part (edge) of the screen is worse than other (center).

I opened the TV and took some pictures. There is no obvious blown parts. I plan to get this fixed by myself if this is the STK392 problem. Some guidance, please: 1) does this look like the STK problem ? 2) if the fuses look fine, do I still need to measure them to make sure ? 3) If there is some manual for this, I will also appreciate.

I have a Sony KP43T75. Had a TV Repair man come out and check it. Seems the Red Picture is out. Quoted $400 to repair. I think I can change out that part muself. I an\m a retired appl. repair lady, or mu husbanc is a A/C service tech. Just need to know part number? Got a place where I can find this out for free?

what do you mean the red picture is out? How is it out?

I'm Sorry, he said the red picture TUBE was out.
