Re: TV remains in standby

PRoblem is in the start-up circuit for the high voltage power side of the power supply. The 5 volt, stand-by circuit, is obviously fine. Need to take voltage measurements on start-up to 32kv side of transformer to diagnose. Possible flyback transformer or voltage regulator.

Lcd tv light flashing but no picture or sound

If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.

When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.

My Sony KDF-50WE655 does not turn on. Only the standby LED Flashes several times and then goes steady green, but the lamp light remains off.

You just count the number of blinks of the standby light before it goes out to green. In sony sets this blinking count ic critical for us to locate the faulty stage. You just count it after switch it Off by Power switch and Switch it On by the power switch at the front of the TV, for at least three or four times, and make sure abut the number of blinks, and report it to me. Ok

Tv keeps turning itself off and the white in the picture looks alittle off.

To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

No picture on a Sony KV-32V65 TV

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 Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking.
