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.
P.S. I've found that a lot of the newer sets are prone to high voltage transformer failure.

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.
U have tools?U know basic soldering?Basic understanding of electronic's?Take the tv aparts,take out the power supply board.Look all around the pcb power supply board for those dead or dying leakages parts call capacitors,they all way bulges up it tops or puff up it tops.Replaced these dying leakages gases capacitors.Ur tv power will stop the random cylces power shutdown.
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.
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.
i had same problem. i took apart my tv and found there was debris stuck between the plastic push power button and the little sensor thing it touches. having it on it would randomly turn off. i adjusted it and it was fine. but now it just pops a fuse lol. hope it helps.
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.
