You need to replace the convergence ic's these are the stk-xxx-xxx chips found on heat-sinks
on or around the main chassis don't adjust the tubes or anything else this will only make things worse after you replace them you can do the user alignment also check the values of the resistors in the circuit as they may be off now pay close attention to the resistors that have a value less than 10 ohms these are critical to the correct alignment if in doubt replace the resistor.

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Not able to adjust convergence


Hello there, its possible it is way out of adjustment where you are no longer able to see it.
I don't know if you want to play with this, because t can be very frustrating inching each line into the proper alignment and it maybe better to call a repair person and pay them and also allow them to suffer in that time consuming headache.
I hope this helps.
