As Bill (or Pookie?) said - a television can be dangerous or deadly if 
you don't know what you are doing. And (no offence intended) you 
obviously don't. It would be wiser to find someone locally who knew a 
little (or a lot) more to assist you.

That said, the TV's component voltage ratings are mostly unrelated to 
the local mains voltage. The TV has its own power supplies and 
voltages will be what the designer finds appropriate. Many will be 
less than 220v and some will be higher.

If the circuit uses a trimmer then it is HIGHLY likely that a trimmer 
is needed to adjust the circuit's operation during setup. As a rule 
TVs don't use a dear component where a cheaper one will do. A 50v 
capacitor will QUITE POSSIBLY do OK voltage wise.but may not.

If you MUST play inside a TV.

- Turn off power at switch at TV and at wall.
- Unplug from wall.
- Leave for a day or so.
- Then regard everything as possibly live and act accordingly.

The above may well be overkill, but always remember your overkill 
factor is 1 - you only get 1 (physical) death (unless you are a cat). 
Even Pookie only gets 1 death.
