Why do old tvs stop showing a picture and the brightness fades even on maximum?

The sound is great, but I cant see anything. Its anoying. How much to fix that?

It's a big box tv on wheels.

    First you have to haul the thing, then expect to pay at least 500.

    Might want to hoard the tv in storage, or consider learning to repair it yourself.

    I actually have a very old book that has all these DIY home repairs like washer machines and tvs.

    If what you have is a CRT projection TV 

    (which seems likely from your description),

    fading is a normal consequence. 


    You could have the CRTs replaced, 

    if replacements are available at all (rotsa ruck!) 

    and the high voltage circuitry rebuilt, 

    but the cost could be on the order of $700 to $1500 ---

    Not exactly cheap in these days of $500 large-screens. 


    Consult with a local TV repair shop 

    (provide the brand and model number when you call)

    to find out more.

    Depends on whether you can still get the components such as the switching transformer/tripler stage,( HOT) HV transistor and snubber capacitors. CRT's don't last forever. Dependent on whether all electron guns are still working and focusing,convergence,deguassing coils are still intact and working.
