Sometimes the screen goes blank. It seem to be alot looser now and its only 3 years old. It doesn't stay completely up unless I keep adjusting it

I would reboot into safe mode, then run your anti-virus/anti-spyware software again, then try rebooting in regular mode and see if that fixes the issue. It sounds like it could be a hardware issue, though... possibly a loose connection or faulty screen, if the virus/spyware search doesn't pan out.

You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.

Hi, Replace the bulging capasitors on the main power supply board. Thanks.

bad connection, soldering goes old .using soldering iron, locate bad connection and redo them agin

Try to reinstall ur windows

The screen cable is most likely damaged. Try connecting an external monitor. If it works, you need to take the computer to a repair center to have the cable changed.

The effect you described sounds a lot like a failed solder joint.

There are points on the circuit board that are subjected to heating and cooling each time the set is powered up, then down.
The solder joints near these areas can fail from metal fatigue as will any metal that is forced to expand and contract repeatedly.
These fractures are minute and can often only be seen under magnification.
Once found, they are simple to fix; removal of the old solder and resoldering will restore electrical contact in seconds.

If you can find a gray-haired tech nearby who is retired, maybe early since repair is a business stagnated by cheap labor in Asia, he/she will know where these areas are and can robably get rid of your lottery-like operation.
Or, if you have way too much time on your hands and are willing to buy a decent soldering iron and dig into the guts of your set, you can probably find the problem yourself.

While semiconductors do fail (sometimes for the same reason), since the set does sometimes restore itself, it isn't likely that any of those has died.

I would be torn to toss the set if it is otherwise OK for the simple reason that if repaired, it may outlast 80% of those bought in the last 2 years.
It is amazing the number of problems that are happening on new, sophisticated sets and it is traceable to lousy quality in parts and assembly.
I have one LCD set I will probably junk this year that is only 2 years old, flawed when I bought it new, and has a failure producing a vertical black stripe that would require replacment of the $4-500 panel.
Junk - Specifically, WALMART junk.

same problem... tv turns on and off repeadly while the green light flashes. seems as if the tv keeps restarting. please help.

Throw it out the window. Acer sucks.
