sony kv-F29MF1

i have a tv set that won't start...can see an arching inside the crt
electron gun when switch the tv on as long as we on the tv. I can't
measure the voltage because that acrhing and sparking inside the
electron gun make me scare to do that.
Those who have counter the problem please help....

 

If you see arcing inside the CRT, you might as well get a new tv as
there is something seriously wrong with the CRT that is not fixable in
my 50+ years of dealing with CRT tv sets.
