Tv popped and went off, there are 2 circuit boards how can I tell which is bad, power board or audio video board,, no lights on tv work at all, complete zip

If you Heard a popping sound. Most likely it was a capacitor that went bad. Yahoo search capacitor to see a picture.
Usually capacitors swell when they go bad. if you Don't know How to spot it. Concentrate on the circuit board you plug connects to and check to spot the capacitor. You might not actually have a standard capacitor. So look for a film capacitor as well.

Good luck

Wont power inverterit has power to the wall to the power board but the tv wont turn

google the manufacturer and model number and the words "bad capacitor" or "replace capacitor" and see if someone has photos of a retrofit for broken capacitors. You need to know your way around a soldering iron but there are hundreds of computers and flat screens that got bad capacitors installed. For someone who knows how to solder they can look at a photo with the bad capacitors circled, check their own product, pull the bad capacitors, replace and have a great TV again. I did this with a Sceptre Naga 3.

There was one year when perhaps 1/5th of the capacitors made were bad (one factory in china). Lots of manufacturers knew that they had problems but shipped anyway. At least one computer manufacturer has been successfully sued on this.

My TV goes off I turn it back on on it goes right back off.I have to keep turning it on for like 30 mins then it might stay on for a hour. the start all over

You did not give a model number. But, I do know what you are talking about. I have repaired many Magnavox and Philips TVs. There is, in this case a weak capacitor. A bad capacitor will rise in voltage and create a high voltage shutdown, in others a weak capacitor will not start up a TV. For some reason the 25 volt, 47 MF capacitor enters my mind( goes weak/bad in many of these). In any case there is a bad capacitor lurking inside. Thanks for asking and show all hands of support!

You may have bad capacitors on the power supply board.
If you know how to repair electronics (soldering etc) you can replace the capacitors.
Check to see if any of the capacitor tops are bulging up. If so replace ALL except for the Large one which should be good. BAD CAPACITORS ARE AN INDUSTRY PROBLEM SINCE SOME BAD ONES WERE MADE SEVERAL YEARS AGO.

Green and red light flahing tv wont turn on


There is a problem inside the unit that is why you are having the blinking lights.
Blinking lights simply are symbols for you to know there is a problem with either one or more components in the unit.

Mostly, it has to do with power problems, either a bad ic problem, bad capacitor or bad power panel.
For bad ic you will have to assess all the panels in the unit to be able to detect the ic that is faulty, for bad capacitor you will have to assess all the power panel or the main board to be able to check and replace any bad capacitors, and if it is the power panel, all you have to do is to assess the power panel to see if it is burnt or have a bad capacitor, then replace the power panel or replace the capacitors.

Take care

Power bottom is blinking blue, monitor doesn't turn on ? Is this monitor death ?

Yes. Might be bad capacitors on the board. Bad capacitors bulge when they break. A repairman might be able to fix it. Although with the right knowledge and 30 dollars for solder, solder iron, and a couple of the right capacitor might do it for you if you know.are a repairman.

TV won't turn on

If that large capacitors is defective, the TV should still power up normally but it might produce a humming noise through the speakers.
I would suggest to check very carefully the capacitors on the secondary side of the circuitry, specially the 1000uF that filter the 5vdc line.
Let me know if you require further assistance.

I supose you should test the capasitors one by one.

Faulty capacitors :

if the capacitors arent flat they are possibly bad note in the picture the blue / black capacitors are flat. the black orange capacitors all seem bad. the two are bad for sure.
