Question about ViewSonic N2751W 27 in. LCD Television

1 Answer

Powering up and warmup problems

When power up the tv the power light will go green, from red, but nothing else will happen. I have to unplug it to turn it off. I will then power it up again the screen will show a picture but it will crack and pop and buzz LOUDLY! and streaks will shoot across the screen for a good 15 minutes and then it will finally work correctly. Sometimes I will have to unplug the TV 2 to 3 time before the picture will show and then all the other problems happen. As long as I have a blue screen while it is warming up I will not get the loud noises but will still get the streaks across the screen until warm.
If you have any suggestions I would greatly appreciate it since it is out of warrantee!

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

What if the TV want come on and only thing that is coming on is a red light and then want come on??

If it's a VISIO, try unplugging it for 10 or 15 minutes. Plug it back in and try again. If still nothing, take it in for repairs or replace it. There's nothing serviceable by the consumer. Make sure to disconnect any USB or HDMI cables while the TV is unplugged. A problem with a connected device could possibly prevent powering on.

Stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.

thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!

Vizio P50HDM No Picture/No Sound

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to

Olevia Kolin PT-501 LCOS TV Screen remains black and lights flutuate

I have the same TV and had the exact same problem. I had to replace the lamp and power supply in mine to get it to work. Unfortunately...its next to impossible to find the parts, at least the power supply. I found the lamp online and I was lucky to get the online store I purchased the TV from to send me a power supply from one of thier stocked models, but only after I turned them into the FTC Consumer Protection. The TV was sold to me as a closeout but new, as it turned out the tv was a refurb, thats the only way I could get the parts I needed.

Hope this helps and if you need any other information please let me know.

No picture on TV with powerlight on

If you press the power button *on* your TV (rather than using the RC), does the power light still stay on red rather than turn green?
