Sony TV 29LS60B switching ON/OFF/ON randomly

Hello Everybody,

After a normal in function time (between 30 and 60 minutes), my TV switch to ON/OFF/ON randomly.
The time in OFF position is very brief (around one second). The repeat cycle ON/OFF/ON is on a frequency from some minutes to some seconds. I hear the relays to work and sometimes I see the standby led to flash, at this time, the remote control works also randomly.
In rare cases the TV remains OFF (standby led is off and no remote control available) and I have to switch manually the ON/OFF button in order to restart it.

After a period of cooling, it works again normally for some dozens of minutes.

Is there somebody to help me? I thank you in advance for your help.

Hi! You could check the relay also however it seems myself then it might be
the power supply and electrolyt capabities at secondary side, you should replace they. Regards

Replace the M-board and 330K ohm and 470K ohm resistors at the A-board. (I gues R6018 + R6019, they are at the backside of the A-board)
