PHILIPS 42PFL5432D/37 Power Supply troubles

Re: PHILIPS 42PFL5432D/37 Power Supply troubles

I have tested the pins from the power board to the main board and the pins going to both master and slave inverter boards. I don't see any capacitors that are bloated. Unfortunately, after two days of the tv running almost non stop, and always being plugged in, it has never malfunctioned. I am going to put it back together and wait for it to malfunction again. Thanks for all the help and I am sure I will be back.

I had similar problem with my Philips 42" LCD TV, chirping sound was comming and the power on light (blue light) was flickering. i opend and replaced 3no.s capacitior 1500,35v which was little popped up at top BUT no use... then i found 2 Diodes (Zener Diodes) which was getting hot, (D902, D904) removed (original was P6KE120A) and replaced with 1N4007, after that TV is working fine.

cost of Diode was 0.3USD

dazza22 might be worth you starting a new thread as the other sets in this thread are lcd your looks like its a plasma? so might get more response by opening your own thread hope tom66 will see it hes good on plasmas
well worth a read even if your caps look good can still be bad with high esr etc

Re: PHILIPS 42PFL5432D/37 Power Supply troubles

5vdc stby is needed for the remote to turn on set and for the main board to tell the SMPS to turn on. After various check it will turn on the inverters for backlighting. if there are any problems then the main board will tell the power supply to turn off.
If you have 5 volts have meter ready to test the 12 or 15 vdc and 24vdc on supply. They may not be marked! Then you will need a schematic. There are feed back pins on SMPS that is used for control thus bypassing that board fr testing purposes only!!!!
Remove the plug rom the main board. Jumper a 200 ohm resistor from 5vdc to the on pin on the SMPS this replaces the comand from the main board. Does the supply stay on?
Do the same for tosurn on inverter 24vdc. Is there a short across the wired to the inverters? Sometimes if you disconnect a plug you remove a shored board plugged into the supply that causes it to shut down.
Hope this helps.

I have a Phillips 42PFL5432D/37 and need a capacitor C955 it is a 2200mf 16v CapXon. The list of capacitors posted earlier no longer has a replacement available. Can anyone suggest a replacement? Online would be great, if not I live in Batesville, Indiana

Re: PHILIPS 42PFL5432D/37 Power Supply troubles

you can use a 25v 2200uf but here is a good replacement just check the height and size so that it will fit into the spot needed and not stick up too high or be too big of a diameter. shipping is usually cheaper at digikey if you use usps option. as to where if you order from mouser it is 4.99 and you don't have any options because that is the lowest.so if you need anything else i advise on getting what you need all in 1 order.
