Question about Philips 23PF9945-37 23" Flat Panel LCD Monitor
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.
