Question about ViewSonic NextVision N4060w 40 in. LCD Television
I have a n4060w lcd tv that will not not turn on. When you press the power button the green liight comes on briefly and then nothing. Is this a minor repair possibly with the logic board or is this an indication that the back light is gone. Also, if it is a minor repair, does anyone know who repairs them. Please help.
Replace the c21 and c22 capacitors on the power supply. they are both 1500uf, 16 v. When you pull the back of the set, youll notice that they will be slightly bulging. be sure to order quality ones (105 degree, and reputable brand). Radio shack won't have them, so you'll need to probably go online. The caps are around $1 each. order a couple extra just in case. Digikey.com sells them. I recommend you use a low watt soldering iron (15 watt), desoldering braid and take your time.

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

I bought a 40 inch LCD viewsonic flat panel, I've had this T.V. for about one year and a half and recently I started to have problems with it. TV did not want to turn on anymore, pushed the power button LED light would turn on and quickly it would turn off. Held button for about 10 minutes and finally it would stay. But now the TV doesn't want to turn on anymore. Called Viewsonic and they said they can not help me, that I have to take TV to a TV repair shop and if I needed a part that they would provide it. I spent 1,200.00 on this TV and I recently took the TV to a repair shop and found out that the part I need is going to cost me 700.00 dollars. I called viewsonic about problem and all they said good luck with my problem, I feel that for the amount that I spent on this TV I shouldn't have to pay for this problem, being that is a hardware problem and not a mishap problem. I want my money back!!!!!

Had same problem. replaced all bulging caps on power circuit board - eight of them with new, quality ones. Cost me about 14 bucks. Works fine now. This seems to be a common problem and there are "cap packs" online that you can buy which include the rest of the caps on the board that seem to fail (thinking about it now, I probably should have replaced the rest whilst i was there). I would strongly suggest getting someone who knows what theyre doing to replace the parts PROPERLY.
