    it won't turn on When plugged in you hear a high frequeny beeping

    Original problem was that power would have to be turned on and off a few times before picture/sound would come up. Eventually it would not turn on at all. No humming or buzzing noises occur. Not before it stopped working or now. The green power light is the only thing that comes on. We think it may have to do with High voltage Power source but where it is located or it's part # we have no idea

    gaaa i need this tv for movies

  • ctgardengirl Dec 06, 2008

    takes many tries to get the tv to stay on. First 2 or 3 times, there's alot of clicking noises, like it's trying to click on, but can't. No pic or noise, finally after 10 or 12 more tries, we get a a white flash in top center of screen, then off. So the next 3 or 4 tries, (at about 10 second intervals) we finally get a pic, but wiggly, overlapping letters, finally the next try or 2, the screen straightens itself out properly, but (my) right side of screen is waving a bit, not clear to edge - that straightens out eventually too. Always the same side, never the other. Seems to take even longer to turn on if the room is colder. Would love to have some help here, before junking it and never buying a Philips again...

Ctgarden girl, my set does the EXACT same thing! I too wondered if a cold room was an issue. The set is only 4 years old, and I didn't have this problem in my old place where the room was a lot warmer.

Can someone please help?!?!?!?

it may just be a static buildup from the dust.
open the tv and blow it out with a air compressor.

Phillips TV, 27”, model:27PT543S37A REPAIR…
SYMPTOM:
Clicks and turns off after turning on set when cold. Have to turn on and off several times to work, or keep changing channels, right side of screen is black for a while.
PROMLEM: It is almost always a bad transistor and a bad capacitor. (about $0.70 in parts)
SOLUTION:
This repair is fairly straightforward. You will need a soldering iron, a solder ******, and a small torx bit. Unplug the set. Lay the TV on the floor, screen down. Remove the torx screws holding the rear cover on. There should be 10, (don’t forget the 2 by the input panel). You will see 2 circuit boards, the one of interest is the large one near the bottom of the set. This board has a retainer clip on each side that needs to be pulled out to allow the circuit board to slide out. Slide the board out about 5-6 inches. You might need to support the board so it doesn’t slide back down into the TV set. This circuit board should have numbers by each of the components. You want to look for 7461 (transistor) and 2455 (capacitor). They are located right next to each other near the center of the board. The transistor will usually overheat and discolor the circuit board immediately around it. Warm up the soldering iron and get the solder ****** ready. Heat up the solder joint while removing excess solder with the ******. Once the transistor and capacitor are free, check the numbers on each. The capacitor (round cylinder) should have “47uf” on it. The transistor should have “C33725” on it. You can order these parts from Digi-Key (google it) for about $2.50 including shipping if you use USPS option. The part numbers are: 493-1060-ND for the capacitor and BC33725-ND for the transistor. Once you get your parts, solder them in and check TV operation. It should work as it did before. (Wouldn’t it be nice if these companies could focus on quality rather than saving $0.04 here and there??!!??). This repair can be done by anyone familiar with a soldering iron in about 30-45 minutes their first time. Good Luck!!
