Sony Indextron KV-4SV2 trying to repair

[rcpilot23]

I have a Sony Indextron KV-4SV2 TV and I have cleaned the boards the best I could after removing the caps and then replacing them.
The TV has a red standby light and when I press the power button it will turn on and I can hear snow from the speaker.
I have an analogue tv TX which the tv picks up and I can hear the sound ok but the CRT does not startup.
The Heater on the CRT does not glow.
Where there should be 50V input coming from the mainboard to the rear CRT board there is only 1 volt.
That where my knowledge ends, This tv needs a guru to fix it.
Thanks for any advice
The black TV also needs alot of TLC.
