Question about Mitsubishi WD-62525 62" Rear Projection HDTV
If the power is going inside the v but the tv appears dead then the first thing you should check is the power button - the tv must be opened then the power board taken out partially (leave the wires attached) and tested. Plug the tv, press the start button then , using a voltmeter, check that the power reaches the power button. Press it then check if the power reaches the power board. If it does continue testing the power board: the mains filter, the rectifier, the filtering capacitors, the power transistor, the control transistor, the transformer, the ballast resistors, the secondary coils and so on.
At least a basic experience is required - you need to know what to look for and how to look for it. If you don't have it then going blindly is the worst thing you can do, you will damage it even further. Call a repairman.
