I just bought a 32" dynex lcd and saw that i couldn't program my two $5 ge remotes to work it. From reading in this forum and others I'm not the only one with the problem, I thought I was stuck with only the dynex remote. But the dynex website tells you how to get universal remotes to work,
It tells you to try the codes for Orion, Emerson, Memorex, Sansui, Sylvania, Zenith. The second orion code worked for me. both my ge remotes look and work the same but one uses a four digit code and the other uses a three digit code. I used 0135 on one and 135 on the other. There is a good chance that if you try the codes for the brands dynex lists you will find one that works. The 0135 or 135 might work for most dynex tv's.
If you have a ge remote and haven't programmed it for volume punch through you might try it. It allows the tv volume to be controlled using the ge remote even when it's set to something other than tv.

The registration card may help with warranty going through the TV company. But, that's the last option.
You can fix it yourself by replacing this board. The board number should be BA71G0F01043.
The 8 Inverter transformer are the problem. They are on many TV power boards that are causing the same problems.
Ebay is selling a couple for $49. Good price I think.
If you decied to throw the board in the trash, let me know. I maybe able to help you fix it so you can have a spare board. I fixed mine that way.

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.
I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
