Buy one of those spray from radio shack or other electronic store. It comes in a can and sprays cold gas to cool electronic components. Open the TV and see which of the aluminum heats sink gets the hottest. Spray the can on the suspected one. Once you find out which one it is. You can carefully add more aluminum heatsink so it will dissipate more heat and prevent shut off. You may have to rig up some screws and nuts. you would need to position the additional heat sink in such a way that it wont touch any live components. I have worked on an HDTV with the same problem and it worked great. The aluminum heat sink are there to dissipate heat from semiconnductor device but sometimes the design is flawed by not having enough surface area to dissipate heat or it have just the exact surface area and not enough room for slight increase in temp. Sometimes component value changes slightly causing the circuit to work slightly harder but not enough to cause an immidiate shutdown. Adding more heatsink to the suspected cause of shut down to let it work slightly cooler is probably the best solution.

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.

Not connecting to tv


If you changed the video output settings when you connected to another tv then you will have to reset it.Switch the ps3 on and hold the power button until it has beeped three times(not including the first power on beep).This should open a menu,choose option 2,this will revert your system back to default settings.Hope this helps

Tv will not turn on


A: Is there a humming sound coming from the TV set?
Check the brightness/contrast. If nothing still, remove power to the set for 24 hrs. and reconnect and retry. If it's not coming back up, the PCB ("motherboard") for the set has most likely died. Check for warranty information in your user's manual for further instructions.

B: Is the TV sharing an electrical line with a wall switch?
Remove the set from that circuit and try another outlet. If not, follow the Steps for "A".

C: Was it during a power storm, when it went blank?
Check the outlet with another appliance - if that device works, try the Steps in "A".
