Question about Philips 37PF7320A 37 in. HD-Ready LCD Television

Philips TV Power problem

Chassis Model #
Model # 25TR19 C225
Serial # 51095491

First, TV would shut off by itself, and I would have to wait before I could watch TV again. After time, it would only power on for about 2 seconds and immediately shut off. No picture or sound. I read a few forums with individuals who had the same issue. Some are saying that I should replace the fuse and the PTC thermistor, while also disconnecting the Degaussing Coil. Others are saying that this is just a simple fuse problem. However, my fuse still seems to appear intact, and it is not blackened. I have not made any repairs yet, because I want to be sure about what I'm actually repairing. I've also checked all of the capacitors and resistors. There does not seems to be any erosion and all are still enclosed. I do not plan to throw away the TV set because I do believe that it can be repaired. I appreciate any input on the issue. Please post possible solutions or any steps that you may have tried regarding to the issue.

I can't be the fuse like you say it is not blackened or open. Set may have a loose solder joint in the power supply look around large IC's and resistors (anything that genrates heat) can cause this problem. A faulty high voltage trasformer can do this I will check and see if I have any info on this particular chassis.. Oh yeah the deguassing coill is not doing it.

Philips LCD TV power cycles on and off during power on sequence. TV will not power on.


This typically indicates a power supply issue. In order for the TV to protect itself, instead of staying on and causing over heat and potential fire, it shuts off. Contact Philips for possible warranty info.

Philips 55 inch tv weirdness


If it is turning off by itself then your power supply might be going out. If it does not bother you too much right now I would wait until it gets worst. Depending on how much you use it it may not get worst in months.

Philips TV picture will not work.


Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Philips flat screen TV MODEL ID 19PFL5422D/27


I bought the television less than a year ago, so I called Philips Magnavox and they asked for the serial and model numbers. Next thing I know they asked for my name and address and Philips is sending a brand new television to replace it !!! The new one should arrive in about ten days. How's that for service? I'm very happy that I bought Philips and I will do so again. So don't forget to keep all the paper work that comes with your new televisions,especially Model and Serial numbers ! Thanks for asking , Debbie Hoffman

Go to philips website and download the latest firmware and install via usb. The fw corrects random power on and offs. If that doesnt fix your problem, the tv is going into error protection mode do to a voltage problem detected by the power supply.

That will be hard to diagnose as everything will test ok as it works before shutting off. The best way is to run the set and use a temp gun to find out whats overheating and go from there.
