Dynex DX-R20TV flashes blue screen
Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.

Looking for At&t uverse remote
you dont need the code for real all you have to do is follow the steps necessary to enter a code but instead of entering code press the channel up button repeatedly until it changes the channel when it does press enter/ok or similar button and you have a nice working remote for your tv without the code!!!! Hope this works out for you, it has for me everytime i get a universal remote its just a lot faster to just keep pressing the channel up button instead of unfolding the paper finding codes and what knot. GOOD LUCK!!!!

DX-R24TV I had just 3/4" Horiz. I change 680mfd
About the service mode, service manual for Dynex CRT models is not easy to find.
Test the following, it works on some Dynex and Insigna TVs:
Take apart the remote and find the hidden buttons inside the remote.You should find several switches not connected to keyboard. Locating the right ones is a problem that you must solve on the spot.
Turn the TV on and push down first the left hidden button and then the right hidden button without holding. If that worked the word TEST will be displayed in upper right corner of the TV screen. Use number keys to select menus, nr.1 and nr.3 have video adjustments needind in convergence.
That is the way it used to work on Dynex/Insignia CRTs.
by the way if the "Raster has About 1/2" black at bottom till tv warms up 5-10
minutes" that means that the problem cannot be fixed with service mode
adjustment. Problem is a defective component. Check STK ICs soldering
joints, read Ohms on resistors and ensure they have continuity
If any of this help, do not forget to accept the solution.
