Question about Philips Magnavox 27MS343S 27" TV

1 Answer

Philips 27PT6442/37 power

My TV randomly died about a month ago and I just got around to pulling it apart. I noticed a fuse was blown and after a little resaerch found that this is a common(extremely) problem with this model. I replaced the fuse with a 4amp 250v slow blow. Now I get power, but still nothing. I hear a series of high pitched clicks that sound like they are coming from a transformer. Philips technical support wouldn't even tell me what the error code(flashed by LED by power button) meant. 1 long flash then 5 shorter ones, if that helps. This set is under 2 years old, and should still be functioning. I would love to resolve the problem without spending the cost of a new TV in fixing this one.

Sounds like you have a short in your power supply load. Probably the high voltage transformer and/or horizontal output transistor. Stargazer P.S. I've found that a lot of the newer sets are prone to high voltage transformer failure.

I have a Philips 32PFL3505D/F7. This is an unusual circumstance, but when I got the TV it was not working. It had no power coming to the TV and the reason I know that is because when I plugged it up and...


not an expert on this but be careful of power boards as the source voltage rating. If you purchased say an USA it would be 120V and if your power is 240 V then power board replacement will blow up.
check the voltages coming out of the power circuit board to the various tv . Check you tube as there are some good videos on what sort of voltages come out of the power board. One of my previous postings yesterday has a video you tube link that explains voltages on a different model tv.

My 2005 Phillips 27 in TV will not come back on after a power outage....


A power surge may well have blown your fuse. Check the fuse in the plug first. If you can't check it, just swap it with a known good one. If that doesn't do anything, then it's possible there may be a blown fuse on the TV's power board. If you don't know what you're doing, don't take the TV apart; there are high voltages stored in capacitors, even when disconnected from the mains.

2001 Sebring Convertible Starter Fuse Problem


The reason that you are blowing fuses is that your starter is drawing too much current. This usually means that the starter is failing (too much internal resistance). By increasing the size of the fuse yoiu are running more current through the wires than they are designed to handle. This can melt the insulation and maybe start a fire.

Philips 26pfl3512 LCD TV loud power supply discharge


The "certified servicers" should have been able to identify a power supply that is breaking down at random. At random failures only occur when the TV is in your home, never in the shop. :-}. Eventually the power supply will fail completely and will have to be replaced.

TV/VCR/DVD Combo won't turn on. Power button lights for 2 seconds


You have possibly

A blown fuse - likely
A faulty power board -likely
A broken power button -unlikely

Note that the voltages inside a television are deadly and I would recommend having the tv looked at by a professional.

Try unpluging the tv and plug it back in after 30 minutes, that should be enought.

Durabrand portable dvd player PVS33701


Take it back. I had the same problem on my PVS1371. Only used it a couple of times and poof...it died. Being an electrical engineering student, I promptly took it apart thinking it was just a blown fuse on the board. Well the fuse was blown but so were the Buck-Boost regulators in the power supply. A quick google search for part numbers and cross-references was fruitless, nobody that had them would sell in quantities of less than 300. :( I am going to take mine back and get another (different brand) player. Sorry for your loss.
