Vidao 32E66 will not turn on

[Papajohn]

The orange light in the front turns on but nothing else happens.Removed back cover looked at the caps nothing puffy.Checked volts on wires where it's says 5v or 24v on the power supply that is what's there.

So what should I look for or test?I tried to find anything labeled ps/on and tried pressing the power on and testing each wire but no change in volts?

I did find this tv at work laying on the ground face up.Work for college apartment complex.We find stuff like this all the time and hoped some of it can be repaired.

Looks like they are made by haier and sale for 200 new.So wouldn't want to spend more than 100 trying to fix it.

So heading is misleading - it does turn on but no picture.
Have you a source connected - a video playing might be good.
Is there any sound - try cycling through the source/input as you wont know what it is on at the moment.
Close up in focus pictures of each board would help

Shouldn't the orange light change color when hitting the power button?Even with nothing connected.

Tried connecting DVD player nothing on screen also no sound.Orange power light stayed the same.

Ok - Did you cycle through the inputs when you had the dvd connected?

Can you report all the voltages on each pin on con4 relative to aground screw. - You need to do this with all connectors in place.

Have you seen the back lights flash at any time?
Often on combined power/inverter boards there is a fuse connecting the two but I can see one. May be on the back of the board - can we have picture
of that please.

STB pin is the PS_ON pin. So the LED is on orange the minute you plug the TV into the outlet, and when you hit the power button, it still stays orange?

Yes tried biting the input button but no picture on screen at all.Tried the ch and vol also.

Con4 would that be the main plug going in between each board?The large and small ones are marked on the board 5v,24v,12v each had matching volts between what was marked and at the pin.

Only thing I seen close to a fuse but not sure is the yellow box in the lower right corner of the yellow board,but it seemed to be soldered to the board??

Yes soon as I plug the tv in the light turns orange and never changes color or flickers while pressing any buttons.

Also tried plugging it in and turning on in a dark room to look for any glow and can't see anything.Tried holding power for 30 seconds also didn't help.

No - yellow box is not a fuse - there is a black one right at the end but that must be ok. I am now looking for one on the back of the board - please post a clear picture.

Is there no flash at all from the screen - obviously you need the lamps plugged in.

You could also test to see if there is any voltage on the capacitor in the middle of the power board near where it says low voltage
The black one with a stripe - not the blue one.. We ask for clear pictures so we can see the part numbers makes it a lot easier.

Yes I meant the long connector to the main board please re test as I said and post results as
Pin1 - 0v
Pin2- 5v and so on

Yellow board part number is mib323d.No flash from screen.

I will test voltage when I get home from work today.I will try to get a better picture using iPhone 4 to take them.

Thank you for the help so far.
