<!-- from fixya rte -->Back light comes on then goes off - Liquid Video A170E101 Monitor

if air coming out back is strong it might be a bad sensor somewhere

The warning light is telling the driver the alternator is not charging the battery. The alternator and wiring would need to be checked.

Set is in protective shutdown--best thing is to take to a shop and get an estimate.

I'm having the same problem right now. I get the green light for about 5 seconds (not Blinking) then the light goes out. No sound or picture.

obviously not a mechanic
with bad sensors you would have starting and noticeable engine running problems
have the fault codes read by an accredited service center and check the EVAP system

TV comes on stays on for a short time than goes black with loss of sound green flashing light untill TV comes back on. takes maybe 2 min.

power light comes on and then goes off

MY TV TURNS OFF AFTER WE TURN IT ON IT GOES BACK OFF A FEW TIMES AND THEN STAYS ON. AND WHEN I COME HOME FROM WORK IT STARTS ALL OVER AGAIN, THAT HAPPENED FOR 2 WKS NOW IT JUST GOES OFF YOU ONLY SEE THE GREEN LIGHT ON THE FRONT COME ON(POWER LIGHT) AND IT GOES RIGHT BACK OFF IT WILL NOT STAY ON

you have a bad power supply....

I need the model number of your set. And can you count exactly how many blinks the power light blinks when you press power? Please respond to this same post so all comunication will be available for each response.
