Question about Radio Communications
Depending on the frequency you want to transmit video on, you would have to modify the synthesizer to produce RF on that frequency. That may or may not be easy. Then, you have to build a wide band modulator (DC to 6MHz) that can modulate the DC voltage to the final RF stage. If you want audio as well, you would have to build another modulator at 4.5 MHZ (or whatever your audio carrier frequency is for your TV standard) and add this to the video signal.
Check the ARRL or the RSGB HAM Handbook for more information.
Doing this modification will not be easy!

I am assuming you have called out for a radio check and not gotten a reply, or even better tested it with friends radio. Just because the meter doesn't mover doesn't mean that its not transmitting.
So as long as you tested it with another radio, and it is not transmitting it could be any number of things. If you have never had antenna tuned so the swr is low, or your swr was high for a long time, your final transistor is most likely blown.
TX switching transistor could be blown, trace could be gummed up.
If your ant light is coming on, the is a problem with your antenna. Could be disconnected, and that can lead to a blown final.
At any rate, your problem most likely requires a tech. Take it to a repair shop.

What you have is an amateur band radio, which requires you to be a licensed operator to use it. It is possible that the frequencies have been removed from the eeprom prior to your purchasing same.
You can have Rx only frequencies programmed by an authorised 2-way workshop, but until you become a qualified amateur operator, you will not be able to get Tx frequencies programmed.
