Question about Sony KP-51HW40 51" Rear Projection Television
My TV couldn't turn on. The red light flashes six times.
Had the same problem on my samsung LN-T4066. TV repair shop said it was fried. Couldn't be fixed.
Before I trashed it I took it to the Geed Squad at Best Buy. They sent it to there repair branch in Dallas. They fixed the problem for $84.00 ! Plus shipping. Said they had to replace four "caps"
Don't know what the caps are, but I was pretty happy with the Geed Squad.

I repaired a KP53SH30 with 6-blinks error.
Sony says the error indicated loss of or short on the 5V regulator. The 5V regulator was bad, so I looked at the 6-volt regulator (it supplies 6-volts to the 5-volt regulator input.
I found a bad capacitor on the "G" board. The top was bulged. It was in the 6-volt power supply. I replaced the 6-volt regulator, the two caps on the input, two caps on the output. I also replaced the comparator chip. I don't know what part was bad, but these parts did the trick. I bought all of the parts at Mouser for about $10.00.
If you are a techno, I can send you the service manual if you need it.
I just noticed your code is 4-blinks.
Sony says it indicates +/-15 volt not supplied, and IC8003 is faulty. Hope this helps,

The blink code means that something on the board is over current/over voltage. It could be an overload of the +5 line (A/B boards) or the +5 line is shorted.
The TV needs to be opened up and the boards checked. You may be lucky and only need a thermal fuse. Also check your bulb.
I hope this helps.
