I have a tv set which doesnt work. when power on pilot light turns red then pressing the secondary power the pilot light turns green then turns red color immediately. it has a relay

Sounds like a power supply or switch problem.
Some switches have a brief contact made when turning on so this may be faulty or it could be the switch mode transistor that is borked.

SANYO TV WILL NOT TURN ON TICKING NOISE FROM REAR Above is your service and repair manual, Below is your user manual, please use these and you should be able to get a result.
This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an Akai, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand.

Bush LCD 2 will not switch on at all, no light at all.

If the TV has no power at all, not even the led light on, and does not respond to remote or button, then the most common is a faulty power board inside the tv.

Tv won't turn on

Most likly it is a problem in the power supply regulator circuit. pretty common for Toshiba TV sets. If you know about TV serviceing, first thing to replace would be the regulator IC as that is the problem 80% of the time. if that does not help then you will need a schematic to trace out the regulator circuit. Good Luck PS please dont forget to rate this thread.
