Question about Sony KP-51HW40 51" Rear Projection Television
I have a Sony KP-51HW40 (bought back in 2002) that recently the red color is offset about 3 inches to the right so you can see the red shadow. Everything else seems to be working fine. I have the service manual and tried to adjust the PJE Red settings but could not make it work like before. The Timer/Standby indicator blinks 4 times which the manual says mean IC8003 fault. The PJE ERR code is 111 which the manual says it means the Red Sensor 1 low output. I think it is a hardware part failure but before I open the TV and try to debug and start replacing part, do you have any recommendation what to look first and how to proceed?
I saw an entry in this forum to replace IC8003, where can I get this part? Another entry says to replace the Red Convergence Board, is that the same as CR Board (A-1332-240-A)? Where can I get this board? Another entry says check the blown fuse, which particular fuse should I be looking at. The manual list several fuses. I have a voltmeter, any other thing I should be looking at?
Thank you for any input.
The two ICs are called stks and this set uses the STK 392-110 (I am
pretty sure) made by Sanyo. They are available online for $6 and up.
Stay away from the cheap ones. I would try partstore.com first.
Replacing them is not so difficult if you have replaced an ic before and know how to ease them out without destroying the foils. Then solder the new ones in. But be sure to apply the grease carefully; otherwise they will overheat and burn out too soon.
