If your country uses the PAL TV system make sure the TV tuner is not set to NTSC.

It might be the power supply board. There is a repair service which addresses any problem with the power supply board, not just bad capacitors: http://www.coppelltvrepair.com/p/783/soyo-mt-sytpt3227ab-power-supply-board-repair-service-no-power-shutdown-etc

Check the remotes instructions

This TV is not Wall Mountable as the Control Box protrudes and is therefore not suitable for a VESA Wall Mount.

The t-con board is located at the top-middle of the set. I have enclosed a picture of what they look like.

sounds like you will need pro help, best to be safe than sorry.

Complete loss of power points to the main power supply, a weak point in the majority of set failures.
Leave the set unplugged overnight to allow any residual charge to bleed from the power supply. Open the back panel of the set and look for a separate board that appears related to the incoming AC and has larger components on it; cylindrical cased capacitors and blocks that are transformers and chokes. If you find this, it will likely be something you can remove and replace yourself. Take a picture before removing cables or the board, although different connectors normally preclude incorrect assembly. Look for a part number on that board and contact the manufacturer to inquire about repair or replacement costs. Even if repair is offered, it may not be much cheaper than a new board. If you go with a new board, don't toss the old one, there are smaller companies specialized in the repair of these and you will probably need a spare.

If you want to know how I did it send me $9.95

400.00 bucks for new power supply. No help from Customer service. If you live by me I will give you the guys name.
