Question about Televison & Video

Open Question

Viewsonic n4060w black screen, no video sound ok. So I've been reading this forum about the problems others have faced with this tv. I decided to purchase pair of inverter boards. After installing them the same problem, no difference. I swap the boards to see if I can find a defective one, nothing. I can see the black backlight on, I have replaced caps on the psw before. Can I suspect the psu once again or am I missing something?

SOURCE: ViewSonic NextVision N4060w 40 in. LCD TV, will not turn on.

While this isnt an exact fix at work, you will at least be able to view your tv. We have one at work that would do nothing when you hit the power on button, just the usual geen led flashing. We pulled the cover off and found the bulging caps, more than likely from brown outs. But we also found that none were holding a charge. So we held the power button on for at least five min, after the led would stay on for about 30 sec and then turn off. We kept hitting the power button and the screen would try to come on. It finally did. After it did come one we can power on and power off aslong as we dont turn it off for more than 10 min. After 10 min of it being off we have hold down power button again and start the whole process again. So the main problem i believe is the caps arent holding a charge, to be able to kick the high voltage circuit on. We did not replace any caps but if we do end up changing parts will post what was changed and cost. Hope this helps

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find. If the tech installed a used power supply, it may be bad also. 3 years are typical for capacitors to go bad.

Cracked lcd on viewsonic n4060w


Ultimately repairing the screen is up to you, LCD's are not cheap.

If you decide not to repair it, I'd be interested in the boards off yours.
OR
You can by mine, (LCD) is in good shape.
