ViewSonic N3250W Television - Page 7 Questions & Answers
ViewSonic 37" Wide (N3733W) TV Set that is connected to Direct TV has picture but no sound.
Based on your description, it is possible that the power supply is starting to go. Before doing anything, first check to see if it is the TV or the source. Use a few different sources to narrow down the problem. You didn't mention what type of hookup you used from the receiver to the TV. Assuming you are using HDMI, it is possible that the cable is intermittent. Try using a different one. Also try as below.1. Once the TV is working with sound, what happens if you turn the TV off and then back on, is the sound still there?2. Use the TV antenna input to see if you can replicate the problem using an antenna. If the problem is indeed the TV, it should do the same with the antenna.

There appears to be power to the tv but no picture
When you say no picture, I can only assume you mean that the set will not turn on. The most common problem with Viewsonic LCD TV's is in the power supply. Depending on your level of repair knowledge, you can either replace or repair the power supply. For more info, post the model number and include a better description of what the TV does or does not do.

Viewsonic won't power up
I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves
checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

I have a ViewSonic RC00136P remote control. It
Okay here's the fix.
Remove batteries. Re-install them wrong side
in! Don't panic.
Reverse the direction of both the battery cells and
install. Press "Power" button a couple of times and a few other
buttons a few times. Then remove batteries and re-install the right
side in.
Voila.
