Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Kp51hw40 Hi... i read somewhere where you had said that if we order the ics from that parts store you recommend that they would provide instructions and pictures on how to replace the ics. I ordered two but didnt get instructions on removal and insertion. What gives. I can solder, so i guess i will just have to wing it.

    Hi SL... I swapped out the ics (2). Still not workin. However, its probably b/c i butchered the job.(poor soldering). I switched to a better desoldering iron and boy it works fast and great. The last pin was murphys law all the way. Wouldnt take solder for nothin. I would take out the board completely for better positioning but those two red high voltage wires wont come out. The service manual says twist and pull but wont budge. Can I clip em? I will resolder again and see. Can I send you the board? If its not the ics what else could it be? But first i will resolder then see. Thanks a mil !!!

    We are slowly getting back to normal, the power outages were a big hassel especially at work. Doing projection repairs by flashlight and propane soldering irons is not all its cracked up to be. Good luck with your repair.

The blue won't align with the other colors. It looks like a double pic, but it's only the blue that won't align with the others.


HI:
One of your convergence IC have failed. I recommend having both of them replaced as the other may not be far behind to fail also, They are large OP-AMP IC's that control the beam in each of your picture tubes. They may use the part# STK-392-110, google this number for better info on the IC's and where to get them. If you know how to solder and unsolder electronic componets then you can install them yourself, saving you some money. They are the two or three LARGE BLACK IC's mounted on a large metel sink. Typical price for most local shop to repair this problem is $130-$210.00 depending on what IC's part number is installed.
