When on button is pressed green light comes on,four clicks can be heard then red light comes on then power goes off
I have a Philips 37pf9975/12 and after about 1hr it switches itself off the green light stops on the side but you loose picture and sound. if you push the stand by button it clicks for about 1 min and then turns itself back on???????
Check powersupply fuse...if blown powersupply is bad and if your a teck check for shorted transistors mounted on heat sink. If transistors are bad check resistors for open, diodes for shorts and capacators for low value that are near the blown transistors.
The clicking are relays that are powering the high voltage circuits. See if you can disconnect the low voltage going to the ballasts. Then power up the set and see if you get audio then the problem is in the ballist board. There are monitoring circuits that disable the power supply if errors are detected. My Pioneer Plasma had a bad audio IC which prevented the set from turning on. I removed the bad IC and the set came on. I replaced the bad IC and the set works just fine. You may have a simalir problem.
