Question about Sony KP-51WS510 51" Rear Projection HDTV-Ready Television

1 Answer

Convergence is off, can't seem to fix.

Hi, I've changed the Convergence IC's, but it did not fix the problem. I still could not calibrate it at all.
Other than trying to look for a broken solder joint somewhere, are there drivers I should be looking at maybe?
Also, is this ever a power supply problem? Thanks.

I have an rca r52wh77 it is bowed in the top and bottom. it also is way off in convergence and i can not seem to get the crosshatches to come together. i have changed the fl123 part that was sent in my kit...


Does the kit have a pair of convergence ICs? That is what you will need to fix the convergence problem. The kit should also contain thermal grease(a white paste that should be applie to the ICs before you solder them) and resistors that may also need to be replaced. When a convergence IC blows its usually due to failed resistors.

Wavy green lines and offset during convergence calibration


There is whats called a convergence IC that is going bad inside this TV set. There is only one for all three tubes and the IC number is STK 393-11- and can be purchased here http://www.electronic-repair-kits.com/STK393-110.html You will only need to order one. If you are handy and can solder this should correct your problem. One very important thing is, before you reinstall the new convergence IC, make sure you use a good coating of heat sink compound on the back of the new IC. If you do not, the IC will fail within a short time frames. Only if you are good with a soldering gun should you attempt the repair. If you are not, this repair should run you about 300 bucks or so. Also if you are handy, there are seven capacitors that go bad inside a board called the DM board. These will go bad very soon so while your in there these should be changed as well. If you need info on how to change these capacitors, let me know and leave an e-mail and I will send you the pictorial on how this is done. the IC change you will need to find that, but I do have a service manual if you need one also to help you along if you can follow the schematic. Good Luck

Red green and blue arched horizontal lines on the tv


Hi, you`ve got a bad convergence circuit, involves un-soldering either 2 or 3 large IC`s (you didn`t post a model number) possibly 2-3 burnt resistors and possibly a chemical fuse. A lot of times it`s just the 2 or 3 IC`s, definitely worth fixing (I personally own a 53" Hitachi) If you try this yourself be sure you get original IC`s for the set, theres a lot of bogus chinese IC`s on the internet, acme-sales.net in Orlando Fl. is where I get mine, gl, video-tek

Toshiba model 61HX70 convergence issue


It is a good possibility you damaged something on that PCB that had the IC's, I like to use an upgraded chip the STK394-160e that is designed for HD signal stresses. I dont know why they ordered the convergence board but I suspect it would have been ok, there are also 2 jumpers that need soldering JW10 and JW50 that supply power to the chips and they REQUIRE resoldering or it will fail again. Might try reseating the RED CRT board, check for cables that you may have unhooked to see if they are not seated in their sockets properly, double check every wire you unhooked, Make sure you used a Silicone Heatsink Compound on to the back of the IC's. I dont know what all you unhooked, but check the wires going between the CRT Boards. Check for cracks in the boards to make sure they werent flexed to much. Good Luck.

No Picture after it's been on a while. Audio OK.


ok you have a vert sweep problem and yes its probably connected to in a way to the "tap and fix" problem! Seems to be n intermittant connection on the vertical out put Ic or maybe even on the rgb convergence ic?? The total loss of sweep though tells me that theres two differant problems! Maybe and intemittant connection on the vert output Ic as well as bad connections on the convergence ic??.
