Thomson 32WT45E intermited wor

[ericsul]

Hello,
I have this TV/DVD combo model 32WT45E just working fine now 8 years. Lately the stand by led go off and the TV cannot turn ON any more. after a few day the TV come alive by itself and work fine until the next shutdown.
I checked all the power supply to the unit and everything look fine this is not the main switch or relay problem !!!! very weird failure!
may be someone encountered the same problem. I dont have any schematic or service manual to check more deeply.
Very appreciate any help
