My magnavox 26mf231d/37 won't turn on

Nothing happens when I hit the power button. Is it a simple solution worth fixing? or is it just better to get a new TV?

Look it would be best to at least get a "Quote" from a reliable place for a fix, then you can at least make an informed decision.

My Philips 51PP9200D/37 tv won't turn on. The lighted power button stays lite but nothing else happens. Could this be the Flyback transformer?


It could but it could be about 50 other things as well. You have a voltmeter, and know how to use it? going to need a service manual as well.

If you hear a clicking noise that sounds like the ballast trying to power on the lamp, but nothing happens, the lamp may be faulty.

Either your inverter board or video board is bad. If you can see picture while the TV is on then its your inverter board. If not, video board.

First, I would try leaving the TV unplugged for an hour so the TV can discharge and reset itself.
If this doesn't work, it maybe something simple like a blown fuses inside the TV that needs replacing. Radio Shack or some electronic store will carry the fuses.
If the other two ideas doesn't solve it, we're talking about a power supply board related problem. I can actually look at your TV over the internet. But, the most common problem with flat panel TVs are the power supply board for the screen itself and the main power supply board for the rest of the TV. Commonly a bad capacitor or transformer will be on the board.
If you have some electronic experience and want to repair it yourself, you can sometimes find a Service Manual for your TV over the internet. Normally, costs less than $20. It will have diagrams, schematics, and part number list for the TV.

Magnavox Philips 26MF231D 26 in. LCD Television wont turn on. The green power light is on but unit does not work; it won't power on or off using the power button, and screen remains black.


Most likely you have defective capacitors in the Power Supply. It is not an expensive repair but something that needs to be done by a svc. co., if your not familiar with Switch Mode Power Supplies (SMPS). I hope this helps and Thank You for using FixYa.. Let me know....

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.
