Re: My Tv won't turn on
It probably has a power supply problem or a sweep supply problem?? Your gonna need a schematic diagram to trouble shoot and find out whats bad. if you cant troubleshoot electronics by using a meter or scope then I would contact the manufactuer listed in the owners manuel.. Good Luck

It has a fuse and if the power light comes on and blinks a specific code that would be a error code.
This set weighs close to two hundred pounds, follow the power cord inside the set as it goes almost directly to the fuse which should be a 6.3 amp fuse----careful if its bad, it is a slow blow and special, a Radio Shack or Generic one the same amperage and type will blow for no reason, if its bad don't keep feeding it fuses.
Please check if your surge protector is working properly now. There is possibility that the surge protector is blown off due to high voltage surge.
Check if your surge protector has a reset switch which some of the surge protectors have.
If the problem still persists then you have to call the technician to replace the safety fuse which is inside the TV. The cost will not be much.
I will personally recommend that you change your TV as it has outlived its life being 10 yrs old.
We had a bad storm and lots of lightening. After that my tv (which is plugged into a surge protector) would turn on and then immediately turn off. I unplugged the TV from the surge protector and plugged it into a different outlet and it works now.
This is a power supply issue. Probably in the high voltage stages. Maybe a fuse, regulator IC, or Horiz. Output transistor or all of them. If you don't know anything about TV repair, you should take it to a shop that will provide an estimate to you.
IF YOU CAN , AFTER DISCONNETCTED THE PLUG (MAY BE DANGEROUS) YOU HAVE TO CHECK THE FUSE ON THE BOARD . IT MAY BE OPEN - IF IS IT YOU HAVE TO CHANGE WITH THE SAME RATE ( 2 OR 3.15A) AND AFTER TRY TO SWITCH ON TV - DELFO
If it's not yet a year old it should have some warranty - take it to the shop.. It's probably the HOT (Horizontal Output Transistor) which have been a problem child in this series all the way back to the TXP2745... But don't even crack the case on this one if it's that new - labor might not be covered but parts might. In any event replacing the HOT is not a difficult or expensive job.
Sure, Why not?
It is worth the effort.
If the set is 'dead', it is the easiest to repair.Only 'tampered' sets pose problems.
It could be a simple blown Fuse, or the Power Regulator IC.
This should not cost you more than $100-150 as Technician charges + 15-20$ for spares.
It could also be a defective Horizontal Outut Transistor and short cicuiterd FBT, (tho' it seems remote), but if yes, add another $100.
definitely worth calling a professional techie
