My Kenmark 19" tv won't

Power supply failure

Check its main digital board for fault. Replace it if needy.

Every set has a standby power supply that runs 7/24 when set is plugged in---it means in this case a main power board or something associated with that is not working, Set is not making it from just standby to full on.

Sorry to tell you this i have the same TV.I have just checked the manual it says TO count how many times the light flashes in 3 second intervals.Then turn the tv off and un plug it from the mains.Sorrry then you will have to ring the Sony service centre and explain the problem.

sounds like bad capacitors on the power board. Very common problem. I would look at the caps if any appear even slightly rounded on top they are bad. They should be perfectly flat on top any puffing up means replace that cap.

wait a few day then turn it on if it does not come on ask someone to check it out

Yep, I can help but I am afraid that I won't be able to bring totally good news.

The TV is in forced standby also called "protection". Protection kicks in when an internal fault such as a short (big power draw) or a wrong voltage is detected. The click comes from a relay activated by the protection circuit to force TV to shut down.

All you can do is disconnecting the power cord, checking if there is a fuse built in the power cord, replacing fuse and connecting back after about 30 minutes (that allows power drain). If the TV does not work there are faulty internal parts that need replacement.

If now the TV does not start at all, and not even the standby light is on, then the problem is usually the PSU. The part must be tested and eventually replaced.

I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?
