Hello,
TV in question is Philips Plasma 42pw9982/19.
The fault is that when the TV is turned on red light comes on. It then goes to green but when we press the remote control buttons, it goes back to red a few seconds later.
I appreciate assistance is diagnosis and a possible remedy of the fault.
Thank you. |

Hello,
Some change in the problem now.
Now the LED remains green. When started, TV initially shows some glow and pinkish black striations on the screen (tries to start) and then the screen goes blank with green LED permanently on on both screen and tuner box. Green lights blinks both on tuner part and the main screen with pushing of remote button but no change in the screen.
Any idea where the problem lies?
Thanks in advance. |

Hello,
Some more details about the problem.
I tried connecting a standard crt computer monitor to amplifier/ tuner box unit but it failed to pick-up any signal. I tried both front and rear connections but same result. Should I assume that the amplifier/ tuner box is faulty? if yes, how to check? (Monitor it self is OK as it works fine with computer)
When I start the box, it starts with a reasonable buzzing sound as if some motor is starting or some big system is energizing (this is when Plamsa TV tends to show signs of life and tries to start) but after a few seconds that buzzing sound starts disappearing and only very low level sound of box fan remains there. This powering behaviour remains same irrespective of whether Plasma monitor is connected or not. Lights on box and plasma monitor remains green at all time.
Any clue where to start tracing the problem, may be some weak capacitor, faulty transistor, relay etc. and how to rule-out various possibilities?
Thanks for any assistance. |
