We recently moved the tv and now when we turn it on it has double vision. It kinda looks like a 3d movie. What could be the issue? Is it worth fixing?


Hi,
If tv picture was fine before moved then check dry/ cold solder joints/ connections on convergence output ICs and nearby circuit area.
Local tv repairman will resolder loose/ dry solder connections to solve double vision picture problem.
TV worth fixing if picture is good.
Thanks.

Double Vision (Mainly around the edges of the screen)


Look for your Convergence amps and check the solder connections on them....you may only have to resolder the amps...and if they fail in a couple weeks, then replace them...

If you don't beat up the convergence amps for WEEKS operating them with the bad connections, they can survive...

Tv problem


It sounds like your convergence is going bad.. this is pricey in older tv's. Look inside (but be careful) and see if there are some really big heatsinks with a IC mounted on each one. they should have a number like STK???-???. These are the convergence IC'S- change them, and you should be ok (IF your set uses the STK style IC's)

hope this helps.
