When we have on the tv the volume will go out for like 5 minutes 10 minutes etc. Sometimes it wont come back on. When I touch the buttons on the side they jump and it seems like they arent working right. It's a Dynex 26"
SOURCE: 19'' Dynex TV does not come up as a Computer Monitor.
I had this same problem with the 19" model as well. I had to reinstall video driver with the tv hooked up in order for the resolutions to work properly. In order to do this I used an S-video cable which worked well enough to reinstall the video driver. I did not try safe mode which might have been easier, I just did not think of it at the time. With the video driver reinstalled while the TV is attached to my computer, I know enjoy a crisp 1440x900 screen resolution. Hope this helps.
SOURCE: I purchased my Dynex 26(?) late june, and fine
Bad power supply,Hard to find,They went out of business. may try to find a remanufact,or used from Shop jimmy,or even Ebay. Encompass does not have them. This is why I recomend Extended warenty. I handel all of central FL.Best buy was giving a trade in for another brand TV. If you get rude enough,They might let you return it. Trust me is works often.
SOURCE: My dynex tv will not come on seems to be stuck in standby mode.
It sounds like the main power supply is trying to startup but failed because there is short circuits or the main power supply is bad.
Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.
SOURCE: We have the stereo hooked up to the dynex 42
Since you have it hooked up to the stereo system, you need to go to on screen audio set up and turn off the TV built-in speakers (you will be listening the TV sound through your stereo system speakers), then go to the audio output set up and set it to 'variable' so the audio output of the TV's RCA audio out put will vary with the volume control of the TV (not all TV will alow this function), you will need to set the stereo volume to certain level (around 9~10 O'clock setting) since the sound coming from the TV will be controlled by the TV remote volume control. You can otherwise set the TV output to be at 'fixed' level, which means the sound output of the TV will not be controlled by the TV remote volume control, you will use the stereo remote volume control to adjust the sound level instead. I hope this is clear to you.
SOURCE: need code for Dynex/DX-l42-10A for Dish Network
I know you've probably figured this out by now, since you posted last May, but I figured I would post the solution, since I just found it, and someone else may want to know.
I bought one of these sets the day after Christmas 2009, and finally figured out the code that works with the Dish Network 5.4 IR remote.
I did a Code Scan, and found that the code that works is 721. In the Dish Network listing, this is listed as the third code for Sansui.
Hope someone finds this useful, even if it's too late for you.

Maybe I should explain a little better. soon as the tv gets hot the volume problems come into play. I will be watching a movie and like 10 mins later the volume what cut out for 2 mins to never. I opened it up today and saw a screw that came off the main power board. I cleaned it and put the screw back but still same problem.
