Last night I had been watching TV, I turned the TV off, then turned it back on about 1/2 hr later and it would not turn on. The green light comes on then shuts off, then I get 1 long and 4 short red flashing lights that repeat. I unplugged the TV overnight and plugged it back in this morning, but it still won't turn on and and I get the flashing red lights. The TV is only a couple of years old, what's wrong with it?? I called Phillips support and they refered me to a local repair company. Seems to me a 2-year old TV shouldn't need to be repaired already.

Back again. It appears that the key is the order in which you connect things and switch the TV on or off. It took some experimenting to get to what's reliable. I'll spare you the details and confine myself to what works. 1. Start with the monitor cable disconnected at the laptop. 2. Turn on the TV with the source set to your regular satellite (or cable) signal. 3. With the laptop on, plug the monitor cable into it. 4. Switch the source (at the TV) to receive the VGA signal (from the laptop). Voila! To turn off, reverse the procedure.
