    I have the same problem with my sony kp-43ht20 that seems to be common. My t.v just stopped turning on one day, there has been no problems with the picture or anything and all of a sudden it just won't turn on, no picture or sound and the light blinks about 6 times. We have tried unplugging it and letting it cool off and nothing seems to work. Help please!

    I turn it on and it turns back off and the timer/standby light blinks about 6 times then stops, then a few seconds later it blinks again. Please if anyone can help me with this problem it would be highly appreciated, or tell me if the problem can be fixed.

    Same TV, same headache. It appears the power supply board is ok, and there is no change to fault with the AD, U, or B boards removed, so I am leaning towards the A board. I wish I could bring all my test equipment from work to my house, but I can't. I will however look for those parts in the schematic and see what I can find...

Does Sony offer any kind of recall for this problem? It seems to be a common problem for this model of tv.

Sony kv-27v40 standby/timer blinks 5 times

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 slightly.

It will no longer turn on... the standby/timer light blinks 6 times and then NOTHING... what's wrong with it??? and how can it be fixed or can it be fixed at all

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

The standby/timer is flashing 6 times on my Sony KP-53HS30 TV

no the 6 blinks indicates a missing voltage. If your talking about a sony lcd KD or KE model you probably have a bad thermal fuse. You must also clean or change the Lamp fan so it won't blow again.
