SOURCE: 42" philips plasma

when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.

SOURCE: red light flashes

This is a well known and very common problem with all Philips plasma tvs 42 and 50 inch. The problem is they used under rated capacitors in the power supply. If you have electronics experience or a friend that is, remove the cover and look in the back for malformed or leaking capcitors. Replace them and see if that takes care of the problem. The caps only cost $2 or $3 each, so the cost to try this is pretty reasonable although you might have an added cost of buying beer for your electronics friend. If this does not fix your problem you are down to replacing boards that can be purchased around $300 ea.
I have found my set will come on "finally" after I get the back of the set warmed up and the bad caps finally charge up. Hope this is useful.

Mainboard damaged and need to be replaced, try EBAY for a general picture of prices but you will need your product code wich is located in the back of the TV next to serial number.

SOURCE: the red standby light flashes and when the power

One of the boards (module) has a short on it, and or the power supply itself is failing.
The service center will find the fault using the process if elimination. They will replace the bad boards or modules as required to get the set working again.
