Question about Philips 42PF9966 42 in. HD-Ready Plasma Television

TV won't power on

Just posted by accident under 42pf9996. TV is a 42pf9966. 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 indicator 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.

Re: 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.

What is wrong with my samsung tv

Try pushing the source button on your remote after the red light stops flashing, Keep pushing the source button until it is on "TV". You may have set the remote to one of the aux settings by accident. My dogs do it to me all the time. Good luck.

My sony bravia klv40ex600 won't turn on,the light indicator for power,volume and channel is on, the screen is still black

Hi, have you tried pressing the TV button that is under the On/Off button on top right hand side of remote control? Some times its possible to accidently press the DVD or VCR controls and this by-passes the TV as a remote?
Another cause can be a poor or low battery in the remote itself. If you have no luck let me know & we can try some more things, however, I have heard that The On/Off Switch on the TV can be a problem. Goodluck, Jon..

Toshiba won't function with remote

All universal remote controls should have to setup with the TV by its codes. There are codes, given below, to synchronize the TV with remote control. Brand name of the remote control you have isn't matter. Check these codes. Proceedings also is given. If you want further details, check this link, and select the site 'Electro-help'. pull up older posts there for more details.
Setup codes for Toshiba TV are:
0159 0178 0109 0120 0181 0105 0049 0095 0170 0260 0358 0394 0924 0012 0095 0117 0141

Direct Code Entry
  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

My remote will not turn the tv on it work for about a week. I have replaced the batteries numerous times with no help

Can another remote turn on and off the TV? Do the buttons on the TV itself work (assuming a front panel lock isn't engaged)? Is this the original remote for the TV or a universal remote?

The possibilities: 1) The remote has failed. If you have a digital camera, take a picture of the IR side of the remote when someone presses the buttons. When you review the picture, you should see a bright spot in the picture. This indicates the remote is at least sending a signal. Sometimes the buttons will fail to make contact with the circuitry of the remote (due to wear). Other times the IR transmitter fails (the suspect if there is no light in the pictures from multiple button presses of the less used buttons). It's cheaper to replace the remote than it is to repair it.
2) The remote has lost the code for the TV. If you have a universal remote, try reprogramming it. (Cable or Satellite controllers count in this group).
3) The IR receiver on the TV has failed (if the buttons on the TV work) or the entire board has failed. You can get replacements for these at some sites. Try (minimally used parts) or You will need to open the TV and get the part number for your individual model for best results.
4) The TV won't turn on due to power supply problems.

If you need a replacement remote, a universal remote should work but the low end ones may not access all of the features of the original. Check for buttons that match features like Menu and Source (Input) if your TV doesn't have equivalent buttons on the TV itself. The remotes that are programmed via a USB connection with a computer are the easiest universal remotes to set up. If you want the original remote (or a close substitute that will perform all of the original features), first check if a parts store exists for your TV manufacturer (Samsung for example). Next try and search for the TV model (leave out the manufacturer).

I hope this helps.
