Re: power problem

Listen carefully, if you turn on and it goes off after 2 seconds, you need to change f902 and check q05a00 for short, if shorted, replace it, and then check for 130v and 34 v on transformer, if they are present, your problem has been solved, if you turn on the tv and hears little clicks, replace the optocoupler of the power supply. i did it and got my tv back on again!!!!

Check for opens at convergence ic's, if none replace stk391-020e's with new lead free sanyo drivers or just trouble shoot them.

No Picture and Lttle red light next to power buttons blinks for about 30 seconds

First thing to do is reset ( see link below) and see if it resets otherwise if problem continues it will need some work

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. There are some common breakdowns in the High Voltage circuits in this set. One is the flyback transformer. Another is a small high voltage capacitor in the sweep corrction circuit. There is a cap that goes open in a high voltage circuit (C6532) which needs to be replaced.

My HP dv6000 laptop screen goes black suddenly, without warning. It is solid black if on battery power; if I have it plugged in to power supply, it is black with flickering white lines.

Your inverter is failing. Under battery power there is not enough DC power for the inverter to convert to High voltage AC power and it goes black. Even under charging, there seems to be evidence that the inverter is failing because there it is unable to consistantly convert the needed power. Check the cables on the back of the display and change your inverter.

Tv shuts off, when i push power button it goes back can play for minutes or hours before it goes off again.

Try uplunging the power cord to the tv, for about fifteen minutes or so. That will clear the memory in the tv, you might accidently push the power button to many times at once.

Just figured this out based on a description of features.

You must power on the TV with the remote control - if you use only the power button on the monitor, it goes straight to stand by mode (the amber light).

Your TV is probably shutting down due to excessive current draw. Replace the filter capacitor in the power supply and cross your fingers. This will be a large, tall, and round shaped object near the location where your power cord goes into the TV. It has two pins and one is positive and other is negative. Do not get them crosses when installing new part. keever
