My philips model 42pfl5432d/37 will not turn on or go into standby mode. It has happened once before and unplugging it and plugging it back in did the trick, but not this time.

it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.

SOURCE: Insignia 37" goes into standby mode

I am experimenting with Insignia's and there is a feature whereby if a signal is not detected the TV will switch to standby mode (in about 10 - 15 minutes). It's documented as a tiny "note" in the manual under "Understanding the basics - Turning TV on or off"

I don't know if the TV resumes when the signal is restored or if you need to power on manually.

You are probably experiencing a glitch with the signal or the TV thinking the signal is not there. Are you watching a clear picture when this happens? I would first check to see if the signal is too weak (like using a signal booster). If that is not the case, it's probably the TV acting up.

I hope this helps.

Is this

SOURCE: Philips 50 Inch Plasma Model 50PF7320A/37 will not turn on

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

Most likely a power supply problem. If it's covered under the warranty take it in right away and have them fix it. If not a good Philip's service shop can fix it. They may have a flat fee repair charge?

I have a philips 42PFL5432D/37 that has a shadow covering about a 1/3 of the screen and will not change screen format. Stuck on Zoom setting that doesn't fit the entire picture on the screen. Bret


Try a factory reset to this set, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

How can i fix my Philips model 42PFL5432D/37 Flat screen TV that powers on, but no picture.


The main board to your TV is faulty. It is best to contact the authorized service center for Philips; because, it will be very difficult to get the main board to Philips brand TVs, and after the replacement, a firmware update too will be necessary. This is a skilled work. http://electronicshelponline.blogspot.com/

Philips 42pfl5432d/37 tv chirps when power is on


Usually stems from a short on the power supply board. I have a 37MF337B/37 37" that had the same problem. Turned out the set had 5 leaky capacitors and a shorted diode on the power supply board.

i was a tv engineer for many years quite a while back now and when a led is flasing or pulsing it usualy means the tv's power supply is in over current mode wherebye it shuts down to prevent any further damage due to a part of the circuitry drawing excess current, high voltage transformer etc, you need to get a techie in, sorry.

I have a Philips Model 42pfl5432d with a picture


Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

Philips lcd tv 42pfl5432d/37 no picture


based on what you clarified and my experience I'd bet the problem is in one of the inverters, most likely the main inverter.

Look at the board part number - it's usually imprinted on the board itself - and look on eBay or Google for it.

Another way to go about it is to type in the model number (usually without /37) followed by the word "inverter", e.g. "42pfl5432d inverter".

My search yielded result board number VIT70023.80 and from there you start searching for this on eBay...find a reputable seller (like me, except I don't think I have it) and buy it.

It might be the slave inverter, it might be the master, but from what you describe it's more likely the master.

It's possible to nail it down, but it will require multimeter and some extra time.

Hope that helps!

Power button will not come on either manually or with remote. Cable is working and power is on the circuit.


I have a Phillips. If you have a menu remote press tv. I panicked when that happened to me. I have RR and if you press the yellow A
