Power light is on but no picture or sound and screen flashes

The most common cause of this issue is a failure of the filter capacitors on the power supply board. The board is repairable by replacing the bad capacitors. This will require a little soldering but should only take about 20 minutes total time. Here is a link to a repair kit with the correct capacitors \for that model.

Hello Kevin,

That type of issue is usually caused by bad filter capacitors on the power supply board. As the capacitors heat up they can't filter the output power correctly so the power supply shuts off to prevent damage. Here is a link to information and parts list of the capacitors neede3d to repair the power board.

Television model number 32mf231d/37 does not want to turn on

I have the same problem with the same tv and the problem almost always is at least one blown capacitor on the power board of the tv. U can see for yourself. (be sure the warranty is up for your tv first, if not get phillips to fix this for you) remove the back cover and then the metal top that cover the power board (you will see the red yellow and white AV plug jacks) in there is the power board, you can tell whether or not the capacitor is blown by looking at the top of it, it will be bulging out or leaking. This is an easy fix, u can get new capacitors from radioshack or stores similar to it.

Power light flashes but TV does not come on: no picture no sound. 34" HD Magnavox 32MF231D/37

Check if it the picture may be just faint. If it is it may be a bad ballast or weak back light. If there is none at all, it may be a problem with the power supply. This is the first circuit after the power chord. There may be loose connections, leaking or swollen capacitors or burnt resistors or the IC or the entire circuit may be bad. This is a common issue with these type of devices. While at it check the rest of the circuit for the same items. There are cases where the problem is with the main board.

you are definitely having the same problem I"m having with my samsung.. Cheap capacitors. You will need to replace your powerboard with something similar to this:

I recommend watching a video on how to take it apart and remember to be VERY CAREFUL there are high voltages stored in the capacitor banks even when it is not plugged in there is still risk of electrical shock.

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.
