Re: power up not likely

This could be anything, literally. My first guess would have been the power supply but you have eliminated that. The rest of the unit is really not serviceable by home owners and would be very difficult for someone without any training. About the only other checks you could make is to check all the fuses. All boards should have at least one and may have several, including some microfuses which are typically marked as Fxxx (where x is a number). Additionally look for charred components (resistors in particular) or burn marks on the board. Check for loose plugs in sockets on interconnection wiring. If everything checks OK you need a repair tech. Furthur troubleshooting can only be done by a competent repairman. It does not sound like the problem should cost all that much to repair in relation to the cost of the TV. Good luck.

Tv won't turn on. red power light is out

red light is on, but when the tv is turned on, it immediately shut down and goes back to the red light setting. It is like it blows a fuse or something to that effect.Post Solution

TV not turning on.

Mine was doing that and I ordered a replacement power supply board for it and now it work. It's fairly easy to replace.
