Re: No Turn On

Check all the fuse devices--most are soldered-in pico fuses in the power supply circuitry. They range in value from 2 amp to 5 amp or more.They are usually a light brownish color.

Let me know what you find....T.

Tv power (redlight will come on powering the TV then back off

If the model here listed is correct it may be the actual power switch--it like all the front controls is a tiny micro switch--only supposed to work when pressed but can and does fail in this way--

How to prove/disprove this?

Someone needs to remove the front keyboard and unsolder that 2 pin switch---remote will with the board back still turn set on.

If it works that way either just use the remote or search for the keyboard and replace if can find one.

Only other issue possible is the microprocessor in the set could be bad and we do not want that-----both the front buttons on set and the remote go to the same place inside the set but the keyboard has priority over the remote.

If power button bad, button on the remote will not stop or correct this.

Mitsubishi WD-52525 was working fine and now it will not turn on

This is just a shot - but it worked with my Sony (same problem).
Pressed remote power on button AND held Power button on TV on at the same time.

Set clicked 4 or 5 times and then came on....

Other, most have a (VERY small) reset switch on the rear - near where the power cord enters the TV... Use a flashlight and a mirror to locate it on your set....

52" rear projection tv has no power and fuse is ok

The clicking noise that you are hearing is actually the power relay. Normal operation by either the remote or the power button on the front panel, you would normally hear a soft click just after the press of the power buttons to turn the unit on or off. When you initially plug the unit in to power, you will hear the same click noise. Being that you are hearing it all the time indicates a failed relay. TV's now a days, or at least ones built during the last 15 - 20 years have different Printed Circuit Boards (PCB). There are PCB's for power (which youre dealing with now), sound,video and so on. The PCB that you need to repair your clicking issue will run you about 80 U.S. dollars for the part plus the average going rate for repair from a qualified service tech. You could purchase the part from Thompson Consumer Products repair and fix it yourself, but be aware, there will be no warranty on the part itself unless an authorized tech does the work. Located on this PCB is the power on/off relay, fuse, usually 4-5 connectors for power to different PCB's (depending on model and features). Now depending on how old the TV actually is, you may want to invest in a newr set, the reason why I say that is, is because the new power unit may and can overload the other boards and cause damage to them and now you have a new problem to deal with( along with more money being tossed down a hole.

Good luck

Bigscreen won't turn on at all- no LED's, no sound/vid, get a relay click though

It might be the relay itself, you sound tech savy have you tried testing the transformer and various other main board componets?

Will not power on. Please Help!!

Error code 12 means normal operation. On these models we have found that a switch is sticking on the control panel not allowing the set to turn on. Disconnect the control panel. You will be able to use the remote on it. To find the plugs for the control panel: Remove the speaker grill and front panel, then follow the wire to the connection. Remember to unplug the set before putting your hands inside of it. Tell me how it went. Lead Tech

Turning on SD-P403 Pioneer projection tv

Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine.
