Question about Philips 37MF231D 37 in. LCD Television

2 Answers

Magnavox 37MF231D 37" LCD TV "popped" now won't turn on at all!

I was watching tv the other night when I heard a loud "POP" sound and then the tv shut off. It would not turn back on as if it was unplugged. It appears that something in the power supply is broke but I am not sure. Any suggestions?

Capacitors tend to pop when they fail. Phillips LCD TVs have lots of problems with capacitor failures in their power supplies. I've got my 37mf231d apart on my workbench as we speak. Mine makes a whistling sound which I believe is either a solder fault or a bad capacitor.

A new power supply board is about $150 for that TV. The gamble, of course, is if the power supply took out something else when it failed.

Watching TV and all of a sudden a loud pop came from the back of the set. Doesn't turn back on after unplugging.


Hello
Check its power supply regulator board. The pop sound you heard may be due to an explosion to any electrolytic capcitors on it. If the line voltage exceeds, this fault will happen. just repalce the damaged component. It is best to replace this board as card basis.

TV acts like it is turning on then shuts off then repeat, repeat


When my lamp died the bulb literally exploded. That may be what you heard. Have you check the lamp? If the lamp is ok, the lamp's ballast or power supply might have blown.

Tv went out after loud pop and has clicking noise does not turn on


If you have a Sony DLP, then the loud pop you heard is your lamp.  The lamps last approx. 4K-6K viewing hours.  Read your manual for replacement part number to reorder and very simple to replace yourself.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
