Having problems with your Philips 23PF9945-37 23" Flat Panel LCD Monitor ?

I bought my Philips Flat Screen TV Model No: 23PF9945/12 about 6 years ago. For the past 2-3 years, it's been switching itself off intermittently - sometimes 3-4 times a night! It's been in and out of the retailer from which I bought it several times, with no solution. I've just been putting up with it! Each time it happens, the screen goes black and there are no LED lights on - I have to switch it off at the wall plug, then on again - usually, it stays on for a couple of minutes and then goes o

Suziglantz, A good TECHNICIAN should be able to pinpoint where the problem is. I suspect that as long as the unit has perfect pic and sound when it IS ON, there should be no problem for a tech to find a thermally intermittant solder joint inside the unit on some printed circuit board. Most likely place to look first would be the Power Supply board. They are called "switch-mode-power-supplys" SMPS for short. Here is what I think. Parts are soldered to the printed circuit boards at the factory. But over time the unit is subjected to large changes in temperature. You do this every time you turn "on/OFF the unit. Let's see here, 360 days x 1 ON and one OFF x 6yrs will be approx 2000 cold to hot cycles. I would think that this would not happen for at least 4000 cycles. Again, a tech type person will need to find the poorly soldered component and or the SOLID STATE component which has a thermal intermittant problem. That's about all I can recomend at this time. Do some research on the web and you will find all types of info on temperature related failures of electronic devices. Please rate this response on fixya if you feel it has been of any help to you.

I have the same issue with my dv1000 "If I press the switch at the top left of the unit ( the one that puts the unit in standby when the lid is closed), the screen comes to life momentarily sometimes for 15 to 20 seconds.
