I am trying to get the code numbers for Dynex tv


Unfortunately the user manual does not have a pre-programmed code for Dynex, so your best bet is going to be performing a code search.

To search:

1. Make sure the TV is on
2. Point the remote at the TV and hold down "CODE SEARCH" for at least 3 seconds, until the red light lights up solid
3. Press the "TV" button once and the light will blink once, then return solid red.
4. Press the On/Off button repeatedly until the TV turns off (go slowly enough that you don't keep pushing on/off after the TV turns off)
5. Once the TV turns off, press the ENTER button and the code will save (and the red light should go off)

This may take a while, so be patient, but if anything should get it working with your TV this will be your best bet.

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.
