Question about Sony KDS-R50XBR1 50" HDTV
Wow, that actually worked. Thanks Cliffmail. I did exactly what you suggested and now both fans are running and my TV is working again. I know it might not be a long term solutions, but it is really dusty back there so maybe that is my only issue. Thanks....

I have the same problem and this is caused by one of the fans not coming on when the TV boots up. If you look behind the TV you can see two of the fans without even removing the cover. The one on the left is a large fan that cools the bulb. This is the one that has died on mine. If I CAREFULLY stick a small screwdriver through the fan grate on the back I can give the fan a nudge and it will start up. Then the TV comes on OK. If you have extended coverage then you should be fine - but if they tell you the part is not covered - it should be easy to replace the fan. The problem is finding one. I found one place that sells it for about $25 but they have no pictures - so I am not sure which is the right fan. Let me know how you made out with the repair guy.

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.
