Won't stay on

Check rotor slip rings for tarnish, gen control needs to sense stator voltage is produced

Do the self check.

If you unplugged the set, plug it back, turn it on and allow to fail.

Press both the Menu and Input (input may be labeled device) buttons on the front of the set and Hold both for at least 5 seconds and release both.

Power light will begin to blink a two digit error code like 2 blinks, 2 blinks, pause and repeat it for a total of 5 times.

Let me know what error you find and I tell you the meaning and a possible answer.

Those are all really common symptoms of the alternator going bad on those cars. I would have it checked to make sure it's charging properly.

Ok, same issue here as well. Monitor would come on for 1/2 second and then the backlighting will go off. It's next to impossible to tell, but if you shine a bright flashlight at the screen, you can make out the video signal/desktop.

I have now replaced all the Capacitors except the very large one (didn't come with the kit that was available.) None of my caps looked bad (bulging) including the large one. Unfortunately, I still habe the same issue

So my question is....large capacitor replacement or something else?

With the unit off, grab the carburetor and see if anything is moving. Sound like the cylinder may be loose. Before tightening cylinder screws check if the gasket is damage. If yes then change gasket.

1.Check the device's battery level for at least two bars of strength.
2.If the battery level is low, charge the battery.
3.If the issue is not resolved, remove the back cover.
4.Remove the battery.
5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears
•Release the power button but *continue holding the home button*, for another 30 seconds.

Open the remote control for to clean the keypads from oxide, dust, dirty with contacts cleaner.
2) retight the springs contacts cleaner for better contacts.
3) clean the contacts cleaner very well.

If this doesnot resolve the problem go to repair shop TV for fix it.

God bless you
