Question about Philips 55PP9363 55" Rear Projection HDTV-Ready Television

1 Answer

Philips 55PP3363, No Picture, constant Chirping / Squaking.

The TV was recently moved and would not power on at all. When I opened it up I found 1 fuse socket empty right where the power cord enters the chassis and the other half way dislodged. I re-seated the dislodged fuse and replaced the other fuse with a 250v 4amp slow blow fuse (TV specs show 255watts, 4 amps is probably too much) Now, upon pushing power on, I hear the system power up, and it starts to chirp. No other picture is present. Suggestions? Thank you, TJ

    I have a Phillips big screen that turned off normal but then would not turn on. No power. I opened the back and swapped the fuse by power cord with one from center of board. Now power comes on and sound works but have no picture. At times you can see green colors & projector seems to make a shorting sound. Both fuses were T5H250v. How can you tell if one is bad with no clear middle? Where can you find the fuses? So anyone know the problem? Thanks...

I will assume that one of your fuses had blown. I would venture to suspect that this set was worked on before. What you are hearing is the startup circuit trying to turn the Horizontal oscillator on which will then turn on the High Voltage system on that provides power to the rest of the television. If this is the case I would consider looking at the HV section to make sure things are ok there. Then I would test the HOT to make sure it was not shorted. If it is shorted then you have to test the HOT related components for defective values. If you are not comfortable doing this contact a TV Repair man and inform him of the situation.

I need replacement power cord

Well, if the power cord isn't hard wired to the TV, then the two most likely options are either a figure 8 cord or an IEC cord.

RCA Projection TV : D52W27D Connector BP120 on Power Board ?

BP120 is not used in that model its simply a empty socket that board is used in other versions of the ITC222 chassis in which some use that plug . But your model doesnt use it. Check the fuse on the AC main board which is right next to where the power cord plugs into that board. If the fuse is blown its most likely the flyback and HOT which are causing the blown fuse. If the fuse is good then the deflection board will need replacement. has replacement parts and circuit boards for that chassis and also free tech support is available.

I heard small pop then lost power while watching my lg 50pg20. No red or blue lights on the power switch. What could be wrong?

you are describing a power supply defect. IT may be as simple as the main fuse. I believe the one in this set is a 6.5 amp located on the ps board right by cord connection. IF after replacing the fuse opens a second time you will need to replace the power board.

I hit the source button on the remote of my 15" Coby HD TV and the tv wont turn on now.

It's possible the source button had very little to do with the tv's failure. Maybe it just happened to pick that particular moment to kick the bucket by random chance. Don't eliminate any possible causes in your troubleshooting just because they are unrelated to the source button.

If you're lucky, sometimes there's a fuse holder right where the power cord enters the back of the tv that you can access easily without tearing apart the whole tv. Unplug the power cord first and check that out and at the same time you can use a plug in reading lamp to make sure your electrical wall socket is still working normally.

Good luck.

I unplugged tv to move it across the room now it wont turn back on??

  1. Connect tv directly to socket without any powerboards and make sure the power cord is properly inserted (if it works than any powerboard you have been using is probably faulty)
  2. Try a different power cord
  3. See if socket is dead using another appliance. If another appliance works then the Tv is probably damaged (refer to warranty if applicable)
  4. if other appliances don't work in that socket check your fuse box.
  5. If fuse box is fine then try a different socket (if it works you may need to get an experienced person to fix the socket your trying to plug the tv into)

Lost power completely

If you are comfortable with working in tv circuit boards then unplug tv from AC wall socket, take off back of tv and follow AC cord going inside tv that will take you to power supply board, check fuse on power supply board, replace it with same rating written on it if it found blown.
Replug tv back in wall socket and check if it turns On.
If still problem not solved then power supply board is defective and need to be replaced.
Local tv repair shop will help you if you think its not safe for you to work inside tv.
Hope these info will help you.

I have a gateway desktop computer. Recently moved

Before you actually replace the power supply, check some other things first:
1. Wall socket
2. Power strip/surge protector
3. Power cable
4. On the back of the computer, where the power cable plugs into, is the red switch set to 115? It should be 115.
5. Make sure that the power cable is not connected to a regular extension cord. Power cable must plug directly into a surge protector that is not daisy-chained to another power strip, surge protector, or normal (household) extension cord. Surge protector must be directly plugged into wall socket.

If none of the above solve the problem, open up the case and ensure that all power connections are secure. Also check ALL other components' connections. Any loose connections can cause problems for you.

If everything is secure and the problem persists, replace the power supply.
