Question about Dynex Televison & Video
I had a brand new Roku express plug in to it for approximately 6 or 7 months with no issues at all. Then all of a sudden my TV started acting weird and it would take me unplugging the Roku and turning off the power source to the TV. Can this be fixed or should I just count my losses and buy a new one?
Try ebay look up the model number on there useing advanced search you just might find one.. Good luck.

This is due to incorrect connections between the dish box and the TV. You may find that if you select another input (AV1) on the TV, you will have sound from the dish system, but no picture.
I suspect you are using an RCA type AV cable with red, white and yellow jacks on both ends. You've most likely connected the yellow jack to a socket labelled Y, Pb or Pr on the back of the TV and then selected the COMPONENT input on the TV.
If you are using a cable with red, white and yellow jacks, please make sure they are connected to the sockets on the back of the TV shown below. I've ringed the socket for the white jack in green for better visibility.
Once you've done this, select the AV1 input on the TV by pressing the INPUT button on the dynex remote, then use the arrow keys to highlight AV1 and press ENTER to select.
If this does not solve your problem, please let me know which type of cable you are using and the model number of your dish box. If you don't know the technical term for the type of cable you are using, please describe it as best you can, i.e. how many plugs/jacks are on each end of the cable and whether they are color-coded.
Hope this helps. If you need further assistance, please reply to me by clicking on "Add a Comment" below your question.

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.
