It may be a bad solder joint on the power supply board, it may also be a failing capacitor on the power supply board, It would require the board to be removed from the set and inspected visually as well as with a capacitance meter. Inspecting the solder connections for a questionalble one takes some time, but it may also be faster to simply reflow the solder connections on all the solder joints on the board.

Following up on my earlier post, I replaced all but the (physically) largest electrolytic capacitors on the power supply board, 16 in all, several that exhibited the "domed" top of an expired part. Ta-da! It's been running for several hours and looks great. I have an electronics background, so I was comfortable with sourcing and replacing the components. If you are not familiar with electronics component values and practices, DO NOT ATTEMPT THIS YOURSELF!. The correct parts are critical for safety and performance.

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!

Very carefully. I only would do it after you have verified the warranty is expired per Viewsonic. If it is OOW, then you can call them for a service manual that contains schematics, troubleshooting flowcharts, etc.

My viewsonic n2751w tv will not stop channeling down... have to put weight on top to stop


mmm sounds like a sticky channel switch on your tv itself. Spray some special stuff called Contact cleaner spray available at any electrical outlet or hobbyshop - its a little bit expensive but works great to clean motherboards and most other electrical equipment. Spray while the tv is off and press buttons in between sprays

I wont turn on viewsonic n3760w.


Viewsonic N3760w LCDTV no power. IrishDruid is quite correct in suggesting that you keep it on at all times. If you switch it off you have to go through the hair dryer routine again (12 minutes the second time around). If it does not appear to work when nice and hot switch it off at the mains and it will come on. Presumably that somehow resets it. Thanks again ID.

I cant convert my 24" ViewSonic remote to my Comcast remote


Try and re-do your codes for your remote. If you don't have the codes try this.
Here you go. This will work with most all universal remote controls. If you don't have the code do the following:
Automatic Programming
With automatic programming, the remote control tests all the codes available on the Code List and assigns the correct code for the selected device. Although this method can be more time-consuming, it eliminates the need to look up codes and enter them manually.

1. Turn off the device with which you want to use the remote control.

2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. It should take a couple of seconds for the light to remain solid. The remote control is in programming mode.

3. Press and release power button. The POWER INDICATOR flashes once and stays on indicating the unit is in Power Scan mode.

4. Press CHANNEL up or CHANNEL down repeatedly until the device turns on.

5. When the device turns on, press OK to store the code.

Note:
• To exit without storing the code, press BACK.
• T he unit will search for the next code or the previous code if you press
CHANNEL up or CHANNEL down after the device turns on. (go slow you need to press OK when the TV turns on) if you mess up turn TV off and start over.
6. Press any other button. If the device responds, the remote control has been programmed. If the device does not respond, repeat steps 2-5.
