Question about Philips Televison & Video
My experience with Philips TV leads me to believe you may have some electrolytic capacitors that have leaked or swelled on top. If you remove the cover and check the module where the power cord connects to, you may find three 1000Mfd capacitors at 35Vdc that the tops are swollen. Also possible a 2200Mfd at 16Vdc may have failed. Service to this PC board requires soldering skills. If you replace your parts yourself please observe the + - polarity in each capacitor.

SOURCE: TV not turning on.
Mine was doing that and I ordered a replacement power supply board for it and now it work. It's fairly easy to replace.

I had a pwer supply for my Protron 32 inch TV that was not working. I bought the one on ebay and it stopped working after only three weeks. Ultimately I found a guy who could fix my original power supply for a reasonable price. It been working for a year now with no problems. I wish I would have tried him first!!!! If anyone is interested his email is firstname.lastname@example.org.

I have a 24" Olevia LCD TV. Same symptoms (Stdby LED is on, press power and it flashes off, then back on). The USB cable to the Service Port also worked. But being of sound technical mind, I figured this means that the PC is supplying the +5v to the circuit. What I did was disassebled the TV, carefully disconnected all the cables, and opened it up to reveal the circuitry. I looked over the circuit and noticed the 1000uf/16v capacitor at position CS21 was failed and bulging. I removed the cap, tested it and verified that it was indeed failed. I went to a local Radio Shack and picked up a 1000uf/35v electrolytic, after all, the value is what mainly matters as long as it's not lower voltage than the original. I replaced the new CS21 capacitor back in the circuit (it is polarity sensitive, so pay attention to what the original mounting position is). I reassembled the TV and Viola! Works! No need for the USB cable to the Service Port!
I hope this helps someone!
