Question about Sony KDS-R50XBR1 50" HDTV
My Sony KDS-R50XBR1 has some big issues. When I turn it on, the green standby light will continually blink green. At first it would only take around 3-5 min. then the picture would come on and everything would be fine. But now, it will blink for I would say 10-15 min. with no picture, and then sometimes you can see a faint picture with no sound and the screen ratio size is way to large to fit the screen. I have taken to a repair center and they couldn't find out what was wrong and said it was probalby some kind of "mother board" that was on the TV and that was going to cost me a lot of money (around $1500). Has anyone ever had this problem? If so, what can you suggest.
I had identical problem which continued for months before the screen started to get dim then went completely black with only the audio remaining. This will happen when the lamp and or balast board starts to fail. You can buy replacement lamp off the internet and install it using only a screw driver. Your Sony manual provides instructions. Don't buy any of those cheap off brand lamps; light output might be low.

Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
