The picture flashes on and off there seems to be no rhyme, reason or timing to pin down. Sometimes the "flash" is longer than others sometimes there are several flashes in a quick period.
We recommend you test your HDMI device on a different HDMI input on the TV. If the problem persists then we recommend you replace your cable or satellite box.

Humidity is an enemy to electronics Solder and coductive componets corrode quickly. Since you no longer have power I would just start trouble shooting at the power supply. AC in , yes look for fuse. There is a constant +5 volt from the power supply that goes to the main board. This voltage is present when set is plugged in . This maintains the micro at a standby condition. When turned on a turn on voltage is sent to the power board to turn on power supply. There are conditions that must be met by the micro before turn on is allowed. Lamp door switch is on. If you cant get this constant 5 volts even if you disconnect it from the main board then replace the power board. Hope this helps.

That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter
