    Alright, If you want to replace power supply board then I would recommend to have service/ repair manual copy in hand, that will help you to do repair because it has exploded views, board location details, part numbers etc info.
    LG 37LC2D repair manual is available at ServiceManual.net for small fee to download.

    Of course its not difficult for handy person to replace circuit board in TV and I'm sure your computer experience would help you out.
    Thanks.

HI:
This is a plasma unit and philips plasma's are nortorious for bad power supplys, your problem may very well be the power suppy in the television, it is possible you blew a low B+ fuse on the power supply. There is also a issue with the Y-sustain board failing in this model, If you open the back and looking at the unit from the rear the y board is on the left side of the unit and the PS is in the center. disconnect the Y-sustain power plug from the power supply and turn on the unit if the unit stays on with no red light then the y board is bad. it does the same then replace the Power Supply.

50" philips won't power on. get the 4x red blink led light


i have fixed 3 of this tv, with that exact problem in the last 2 weeks, needs a power supply, you can try to unplug it again, plug it in, hit the power button, as soon as it turns green, unplug it again, after 15 seconds , plug it back in, if power doesnt turn on by itself, turn it on, if it turns red again, emediatily hit power again, may have to hit power a few times in a row, but most of the time you can get it to come on this way, once it is on, it should run ok, until you turn it back off, but not a fix, needs power board

Won't turn on


Hi, everyone. Me too have the same problem. TV just stays in red but won't turn to blue. I tried unplugging then wait and restart again, sometimes it will work but lately that trick doesn't work anymore. Then somebody suggested to open the back of the tv (it's not hard... just a lot of screws and a couple of bolts to remove) and clean (vacuum) the exhaust fan. Out of frustration, I did open the back and clean the the fan (has a lot of dust on the blades) and everywhere where there is dust. Just be careful not to touch any part of the printed circuit board with the vacuum nozzle to eliminate the destructive effect of static electricity. Or while you're cleaning it you have to hold the metal frame with your other hand to ground yourself (by the way you have to unplug your tv before you start opening the back). After the cleaning then covering the back, the tv worked... for only a few hours. It did stop working again as soon as I turned it off then on again. Again I opened the back, this time I removed the power supply board ( that's the biggest board and located above where you connect all your wirings). Got myselt a small brush and start brushing and vacuuming the dust out. I don't know if the cleaning did the trick or it was the unplugging of the connectors from the power supply board. All these work did the job... my tv is still working for almost three weeks now. Another thing, when you have a a time warner cable with a dvr box where you can program its remote to power most of your equipment in sequence by pressing the remote power button, I set it so that the tv will be powered up last considering that power can fluctuate everytime a unit starts up specially when they are all connected to the same power/surge protector... tv doesn't like it when the power fluctuates while it is still starting. Hope these helps.... (Hitachi 42HDS69)
