Question about Sony Grand WEGA KF50XBR800 50" Rear Projection HDTV-Ready Television

2 Answers

TV will not stay on...goes into standby mode.

The TV only stays on for 60 secs at a time. Then it goes into standby mode for about 30 seconds, then comes back on for another minute. Then the process cycles again. I have replaced the projection lamp, but don't really think that was the problem. It is still going into standby mode about every 60 seconds.

    I am having the same problem. The TV only stays on for 60 secs at a time. Then it goes into standby mode for about 30 seconds, then comes back on for another minute. Then the process cycles again. I am going to try the fan solution and get the fan repaired, if possible.

    Exactly same problem as the others have described. The TV will not stay on because it keeps going into and out of standby mode.

I have been having the same problems as others are.The continuous cycling on then off would do it all day long if allowed. I had a rear projection tech look at it. He used the remote to do a self diagnostic check on it but and ruled out that it was the processor the most expensive part of the set. He said that on these sets that this problem was caused by 1 of 2 things 8 out of 10 times 1 needs software upgrade so He suggested that we upgrade the software because it was the lesser of the two this did not help either. 2 a new lamp i did replace one already it went out when the set was only 2 years old but have ordered a new one will post when i get the results. good luck jb

The red LED for the the lamp may flash which CAN indicate that the cooling fan is not operating. This fan is typically very quiet and has failed on MANY units. It is behind the bulb at the very back of the TV and is not "user serviceable". My repair guy says this is common and you can at least observe the fan through the rear grill and if it is NOT turning, then it IS failing.

Picture & sound go on & off every sec, red light blinks 5 times

helloFive 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 slightly.
