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.

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.

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. www.tvrepairworld.com has replacement parts and circuit boards for that chassis and also free tech support is available.
There is a fuse in the power supply board near the end of the board.The tv power supply board is it dead.That the board where the power a/c cord plug in.Power surge by a storm,change the fuse will not help the board to work.Because all those ICS on a power supply board are very sensitive to electrical static charges are dead already.Tries websites like Shopjimmy.com,Ebay.com to buy a whloe new refurbish power supply board for the replacement.
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.

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.
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. Thanks.
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.
