Question about Philips 42PF9631D 42 in. Plasma Television

1 Answer

When I turn the tv on it starts clicking and flashing 2 green lights on the back of the set, no screen on the front. I removed the back panel hoping to find a reset button of some sort, no luck. The green lights and clicking are coming from the large panal in center bottom and smaller panal just to the right of that, (while faceing the back of the set.) Both of the flashing lights are labeled "AK". What does this mean and what do you suggest I do for a next step to resolve?

If you have the experience and the tools, the best thing to do would be to first download the service manual, which you can do for free at the following website:

http://www.eserviceinfo.com/download.php?fileid=47612

It is a multipart self extracting rar archive, and free of viruses.

On page 20, starting at fig. 5-6, there are troubleshooting flowcharts that you can then follow to identify the issue and find out what you have to do to resolve it. There is a built in system which will blink the LED's in specific patterns to help identify which area of the TV is having issues. Again, if you have the experience and tools you'll be able to follow the charts to the resolution of your issue. If you have never worked with TV's then it would be better to leave the diagnostics and repairs to a repair tech. There are lethal voltages inside all TV's that must be dealt with properly.
Good luck with whatever route you choose to follow.

Hello Jeff;
If the TV does not turn on or off, does not respond to the remote
control or the control panel buttons, or has audio but no video:
1.) Press and hold the POWER button on the control panel for ten seconds. The TV will turn off.
2.) Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost.

If the TV does not respond to the remote control or to the control-panel buttons and TV will not power on or off.
• Unplug the AC power cord for 10 seconds.
• Press and hold the POWER button on the control panel for 10
seconds to perform a system reset.

If the TV turned itself off and the light on the front panel started to flash:
• Momentary power fluctuation can cause the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again.
• If the TV does not stay on, press the POWER button on the
control panel for ten seconds to perform a System Reset. If this happens frequently, obtain an AC line power conditioner/surge protector.
• An unusual digital signal may have been received, triggering a
protection circuit. Wait for the light to stop flashing and turn TV
on.

If the TV will not power off, press the POWER button on the control panel for ten seconds to perform a System Reset.

Should you still have problems, call for assistance at 1(800) 332-2119

I would not recommend using compressed air or any other method that would blow dust around- since the dust could make its way into the set's circuitry via the grille or vents and cause problems. Use a vacuum cleaner with a brush attachment instead.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

When I turn on the tv all i get is the welcome screen, and it will not go any futher,there is green light flashing in front of the tv. and it will not turn off with the remote, i have to unplug it.


Hi Andre,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.
Regards,
Jdvillanueva

Mitsubishi VS-50609 won't turn on


What a great tv this is Mitsubishi did a fine job making this one, but......only an authorized mitsubishi servicer should repair it. This set records diagnostic led codes that the technician receives to help determine where the problem might be, not the problem, but in which circuit it might be. The one thing to try is, unplug the tv , let it set for a minute, plug it back in , turn it on and hope it reset the micro. Next , call for mits. service.

Plasma tv


Ok first i have to ask when u turn sound off on TV and get close to the TV does it make a buzzing noise ? If so u have a damaged Plasma panel .
If this is not the problem you could have a bad logic or y-main (most common problem) will need to perform a white screen test on the plasma panel to verify this is the problem.
This is what u need to do
1. Remove the back panel of the TV.
2. Remove the Small Signal Board bracket ( the two long bars on back of the plasma panel, the bracket that is connecting the two with SSB on it, remove this and disconnect the connectors to the power supply (CN1M02,CN1M03, CN1M45)except for the main power plug in you will still need this)
3. Once u remove the SSB bracket you should see a plasma panel resembling pic 1.
4. Place a jumper wire or connect the two pins (CN 2012) on the logic board located underneath the SSB bracket.
5. Also place jumpers on the power supply (J8003 and J8004)
6. Now plug in the power supply, U should hear the relays click and after 5-10 sec you should see a green led on power supply, and 2 green leds on logic board 1 will be solid and 1 will flash.
With this set up you should get a white screen on your TV this will let you know if the panel is bad or not.
Also forgot to ask have u had this TV worked on recently or this just happen for no reason.
