Mitsubishi WD-73735 will not turn on and there are no lights on front. The power supply was replaced, and is brand new. I fix HDTVs, and have had very little problem resolving other issues with other TVs. This one is strange. Need help, please. When I plug it in, you can hear the PS get power, but nothing turns on. Tried the 'Menu' and 'Input' combination....nothing. Tried plugging it in, with the 'Menu' button pushed...nothing. I can hit the 'Reset' button on the front, and there is a slight 'click' noise form the back, but again, nothing. I took it apart most all the way, and noticed no bulging capacitors, or anything out of the norm. Glass fuses didn't look blown, but it acts like maybe a fuse somewhere is blown. Checked all connections, and the only one that seems a little 'floppy' is the one that the lamp plugs into, but it seems to connect okay. The guy I bought this TV from said that it died out of the blue, with no warning, and no warning lights..don't know if that is true though. The 'warranty repairman' told him it was the power supply, then took two months to install it, so when it didn't fix it he said 'forget it'. The guy then said that it must be the 'computer'...not sure what that could mean though. The bulb does not appear burnt. None of the components appear to have cold solder joints. I have no idea where to start, but figured asking you people may give me a lead. I haven't begun to start checking things with the meter yet, because I'd like to know somewhere to start first, or maybe if I am just missing something someone will tell me. Thank you for your input.

Why is it I feel as if two of you did not read my post? There was no capacitor kit. The warranty repairman in support of the extended warranty put a brand new Power Supply board in the TV. I also tried the 'Menu' and 'Device' combination on the TV, as I also stated, but it's a different day, I'll try it again. As for the power button combination, that's interesting, I'll go play with that right now. I'll also look for the reset switch, I assume you are not referring to the one on the front panel next to the volume controls, if so, I pushed that, it clicks, and it doesn't change anything..but I'll look for the one you are talking about. Not sure where that one could be, but I'll look..Thank you all for your quick responses, I do truly appreciate it! Why is it I feel as if two of you did not read my post? There was no capacitor kit.

None of your ideas worked. Leaning towards it being the main board, though I'm not quite sure why the set reset button on the front seems to work, and nothing else does. Seems like that would be connected to the main board somehow, and therefor should not work...don't know, probably need to trace that connection to see where it goes. It almost seems like there is no power from the Power Supply board outwards, but you can hear that energize..like a fuse is out basically. There is quite a few plugs coming off the PS board, so you'd think SOMETHING that it is connected to would work. Maybe it's just a faulty PS Board...possibly need to resolder everything...also tried using a hairdryer on the PCBs..nothing.. None of your ideas worked.
