I have opened the back and all of the caps look good, but the TV will not turn on. What do I do?
SOURCE: Viewsonic N3760W won't power on
Try unplugging the set from the AC power source wait for several seconds and then plug it back in. Cross your fingures and hope that the reset works!

From the symptoms it sounds like the TV requires an Inverter PCB.
This is the part that "lights" the screen.
I hope this helps.

The backlight inverter is failing for your tv. You need a direct replacement part. You can find parts on ebay or shopjimmy.com and you can search my the model number of the tv. Once you get the part, allow your tv to be unpluged for 12 hours before beginning any work. This will allow charges to dissipate and allows for a safe work environment. Once you replace the part you will be good to go. Also, check the power supply for popped capacitors while you have the tv open. Replace any bad capacitors with the same uF value and HIGHER voltage value (EX: 1000uF 10v --> 1000uF 35v)
Thank you and please rate.
