Question about ViewSonic NextVision N4060w 40 in. LCD Television

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

I purchased a new Viewsonic LCD TV model N4060W 40inch in July 2007. I May 2008 the TV would not turn on, when you pressed the power button the green power light would blink once, then nothing. I contacted Viewsonic, who originally claim that the TV was already out of warranty and I had to prove by reciept when I purchased the TV before they would cover fixing it..
Well here it is less than 6 months later and less that a year and a half old and it's doing the same thing. I contacted Viewsonic again explaining that there's obvoiusly something defective with the TV since this is the 2nd time already with the exact same issue. They pretty much said too bad ,it's out of warranty and would not do anything to fix the TV.
Since this is only 6 months from the last time they repaired the TV, this could translate into a costly repair bill every 6 months, if the same thing keeps recurring. The part they replaced was around 8-10" square and looked like it was almost box shaped, not just a flat circuit board. Would you have an idea of the part and how to get it?

Also after reading some of the forums, it seems this TV has a number of defectives occurring as of late, any recommendations on a comsumer group that looks into this type of poor workmanship?

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

Power problem for viewsonic n4060w lcdtv. red light comes on for half a second then goes off but no picture appears. also, may work if you turn it on or off 20 times....it just wont "catch".


I had the exact same problem with my set 6 months ago. Had the repairman look at it and it ended up being a faulty/weak power source. He told me that he could either work on the power source himself or just buy a new one. New ones are very expensive and hard to come by, but he was able to fix the existing one. Got the whole thing fixed for something around $350 to $400. Pretty steep and made me consider buying a new one, but I didn't. And now its on the blink again, so you might consider that.

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.

Viewsonic n4060w power but no menu or source selection....


hello, you will need to locate a service manual for it.

if your going to open it might as well know what to check for.
you need it to service your set.
not processing signal, menu not displaying,
sound like internal board issues.

LCD TV N4060w can not power on


I had the same problem...first it would take two or more power button presses to get the tv to turn on. Finally it would not turn on. It was the power supply and was easy to replace.

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.

Viewsonic n4060w I was changing my chanel from the console, then the screen went blank. I can hear sound. I try to view the menu or sources but nothing. I can turn the tv on and it lights up a little but still cannot see anything. First, I had trouble with turning the TV on/off -- I could turn it on from the unit, but had to turn it off on the remote. Then, the on-screen menus started going haywire in that, as soon as you pressed the menu button, the TV would automatically quickly go through all menus on its own -- so fast, that you couldn't stop it. I had a local TV repairman come and he said that it was either the board for the TV's control buttons, and/or the main board -- which I guess is the inverter board(?). He ordered both from Viewsonic (apparently, anyway), and voila! TV started working again... but only for a week. The new problem was that it wouldn't turn on at all now. So they ordered a replacement for the two boards AND a new power supply. Lo-and-behold, he got a garbled mess to display with the new boards before he put in a new power supply, and deduced that the power supply was not the problem (and returned it). So, he said the new main board that was sent was defective, and ordered another. Today they came and attempted to put in the newly arrived main board, and it was missing capacitors (and, obviously, the TV is not working still). So, they are ordering another. I just sent him a link to an on-line store www.discount-merchant.com who had some parts available, one of which it claims is video board for an N4060W. Holding my breath now, I guess. Viewsonic is a nightmare!
