TV turns red,shuts off, stand-by light blinking 8Times

Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

I have a 4 year old Sony KDF-E42A10 television - the power/standby light blinks red 5 times, pauses, blinks red 5 times again, etc. I have replaced the lamp previously when the light was blinking red 3...

Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

How many blinks is it blinking before it pauses? Let me know your set is going into protective shutdown. It should blink a number of times then pause for a second, then blink again. Try to count the blinks in between pauses. Then let me know
