Question about Philips 42PF9996 42 in. HD-Ready LCD Television

TV won't power up

When I push power button on side of TV (remote isn't doing anything), I hear a click as it tries to turn on. I can see the screen try to come on with a light glow on the screen itself but it almost immediatly fades out slowly. Same with the blue backlights behind the "power" "menu" etc buttons on the side of the TV. Every once in a while, the TV (and ambilights) will actually come on but most often, the TV just tries and then fades off. At the beginning of the symptoms (a few days ago), after I tried to turn the TV on, the red and blue lights on the front of the TV would alternate back and forth each time I could hear the click. As if the TV was trying repeatedly to come on. This all just started one morning, the night before all was fine. Strangely, the TV did the same thing about a year ago for 2 days (TV is about 1.5 yrs old) then was fine until now it started doing it again. After a week now it's out for good. In fact, I don't even hear a click anymore. I push the power button and the little blue lights behind the buttons come on, then fade off. Nothing else. Seems to me it's the power suppply modulator (or something along those lines) that's gone bad. If a fuse, that would be nice but symptoms don't indicate a fuse as a fuse burnout is usually an on/off symptom. Any help would be appreciated. I don't live in the US now and am nowhere near a service shop/person. I want to be able to handle this myself if at all possible. Will be back in US soon and can pick up part if necessary. Thanks for any help.

Not to alarm you but several models that had the ambilight feature were subjects of the consumer products safety commission recall for shorting in the ambilight feature this can be checked on the us products safety commission website do a google search on your model number assuming the panel is not one of recalls the tv probably needs the power supply board there are several fuses on it ; one that you will find open the fuse shorted for a good reason there is power fet or sumthin on the power pcb dead shorted put in a new board call phillips consumer support and complain that you dropped way too much money on a flat panel tv when you could have bought a dlp tv if thats too complicated buy a new one

TV does not turn on? (Relay problem?)


The power supply could be failing intermittently. That's why it sometimes works and sometimes doesn't. Also, the relay could be erratic.

Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

I have a LC-42D62U TV. The powerbutton is on but there isn't anything on the screen no matter what buttons I push. The power button blinks 3 times & the opc button once when I turn it off.


The backlight probably went out. It's usualy one of the cheaper parts to fix because its easy to get to. If you are somewhat mechanically inclined you can probably do it yourself. Do you hear the audio? If so then its almost certainly a backlight. Good luck and if you need more help let me know.

My son was playing his PS3 for an hour or so. I went and turned it off for him when he decided to leave the room. I pushed the ON/OFF button (on the left side of the TV) and realized I had the remote...


1 - Turn on TV and set input to port being used.
2 - Make sure PS3 is connected via correct cable.
3 - Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.

TV won't power on


I am from Australia and this TV is a dud. We purchased it 12 months ago and it has been to repair twice. It is doing the same as the above message. Prior to this the screen would half, horizontally, go black or white with coloured vertical lines. Never buy another of these.
