Question about Televison & Video
I see so many here with no sound/no picture issues:
1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signs of 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 the problem.
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 generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put 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 a standby power supply that runs 7/24 and a main supply (some are combined and some not.
Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and 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 runs 7/24 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 buy and 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 this photo.

My screen looks EXACTLY like that! I called Dynex and they told me my warranty is out and they cant fix it. I have only had this TV a bit over a year. Did you get a resolution??

Hi, There are some DVDs that will not read. Make sure they are windows compatible. (MP4, WMV, AVi) if this still is not working Laser maybe at fault. Clean the DVD disc before playing. Good luck

The main board is faulty. This is the common problem to most of the dynex TVs. As you know there is no repair to this board. Replace it as card basis is the only remedy to this fault.
Replace this board, rather than making surgery to it and wasting your precious time and money. The cost of the board come around $95. OK.
