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.

LOOK AT THE POWER SUPPLY ,lOOK FOR VENTED TOPS ON THE CAPACITORS,IF YOU FIND VENTED TOPS REPLACE THEM WITH THE SAME MICRO FARADS BUT A HIGHER VOLTAGE RATING.

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.

I get sound but no picture then the tv shuts off after 5min. It is a Mitsubishi wd-73837


Popping noises are not a good sign; I suspect the sound came from the catastrophic death of an electrolytic capacitor or worse, the death a a power semiconductor.
Open the lower cabinet and using a good light, look for a smaller, separate board with fairly large parts on it; some cylindrical in shape, others block-like that may have copper wire showing.
If, as common, this board is plugged with connectors into other parts of the system, you may be able to swap the failed board out for a replacement bought from a Mitsubishi service center.Expect to pay $100-$150 US if the set is no longer under warranty.

Pop sound then no picture, just sound


I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.
