First off assume it is broken. Odds are it needs work or soon will.
The set has no real value so it may be a good learning tool
for you. Bringing it to a shop probably will not help. Most wont
touch it with a ten foot pole for many good reasons. Fixing
it is not rocket science. A little basic electronics knowledge. a
meter & hand tools can get you far especially when you add
help from here.
Before you buy you should at least look inside for a CRT "brightener".
Its a round part thats added to the CRT socket. Plugs in series
with the CRT & regular socket. If it has one the CRT is weak or dead.
Good luck
