Question about Televison & Video
Pioneer pdp 501mx, will turn on and green screen for 1 to 2 sec and power off. Sometimes the tv will work for 20 mins and back to green and turn off. I will need to unplug the power to turn it back on. This was a hand me down monitor.
This sounds like a problem in the power supply. Could be that some capacitors have gone bad. Look for capacitors that are discolored and or are potruding from the top. Usually this will be an electrolytic type capacitor. From the sound of the problem you're having the power supply is not properly regulating the voltage it's suppossed to be. A lot of times too in TVs this problem can due to an incorrect voltage in the horizontal or vertical stage. Again a voltage problem. The reason the TV shuts off is due to an overvoltage/undervoltage or current protection circuit so that it will not cause further damage to the TV. Good luck with this. I may be buying this same exact model tomorrow from someone who has the same problem. If I get it fixed I'll let you know.
