Philips 42" plasma almost comes on by itself ? (Otherwise works fine)

Hi all,

I bought this Philips plasma TV from Costco (Model# 42PF9431D/37). It is on the wall in my bedroom. I noticed that it would click as if I turned it on and after 10 seconds click again like if I turned it off when the TV is off. This happens like once or twice a day. Because it has done it at night when the room is completely dark, I can see the screen lights up a bit. It never comes completely on when it is doing this. Otherwise the TV works fine, no video or audio problems at all. After a few times of these I decided to take it back to Costco and got another (same model no.). Guess what happened? ... I got the same problem again :-(. So I decided to do some things to rule out the power outlet:

I plugged it into an extension and into another outlet (away from my bedroom). No change. I plugged it into a UPS. No change I cover the IR sensor in front of the TV. No change.

I finally called Philips and they referred me to a repair center. I just got it back after they had it for two month. The receipt shows they changed something called PSU and SSB. Here is the depressing part ... NO CHANGE!.

I called my credit card company and I can do something with them to return it but I really like the TV. Other than this click on, 10 secs later click off, it really is a nice set. Not to mention that the installation is already done on the wall. Anyway ...Can anyone suggest what else I can check in my place that may be causing this TV to do this ?

Thanks a bunch everyone... comments/suggestions welcome.

Try the easy thing first, put some black electrical tape over the IR sensor on the set and see if it still happens.

If all else fails, just take it back to Costco, they have an outstanding return policy.

I checked their web site and I'm running the latest.

Thanks

There is a setting for the time but it looks like it is only to display it on the screen, I can't find a programmable "On" feature and remember that it doesn't come all the way on. The screen gets slightly bright for the 10 secs then it goes dark after the second click. Effectively turning it off. One thing I forgot to mention is that the front green LED that it is on when the TV is actually on does not turn on during the 10 secs glitch.

Thanks

Hi...

Don't know your set; heck I'm so old I don't know much of anything anymore :)

Nevertheless, can't help wondering if your set doesn't have an auto off menu setting for a certain time of day? (for us old folks who fall asleep on the couch.) And if so, it isn't *slightly* waking up so as to turn itself off?

Take care.

Are you on cable, dish, or using off the air broadcast?

I think that some cable systems periodically send a signal over the cable to disable unauthorized [the authorization to receive their signals has expired -- the bill hasn't been paid] decoder devices.

Could such a signal be activating some of the electronics in your set?

Have you tried disconnecting all signal inputs at night to see if it stops clicking???

I haven't tried this before. I just turn the off timer to 180 mins (the max). It was set to zero ... I haven't been home to hear anything but if it did anything I should know before monday. I'll try your suggestion next if this fails.

Thanks

Could this have anything to do with "burn in mode"?
