If the sides are bowing in like this )( that is called a pin chusion problem, normally you have a problem in your vertical circuit, a tv tech would be able to narrow it down but a good thing to do if is scope your vertical pulse from the vertical IC to narrow the problem down

If the symptom didn't cure by convergence adjustment through the remote control, this is an indication of faulty convergence board inside. You may replace the convergence IC's and some of the resistor around because its already gone bad. You may also replace the entire convergence board for your convenient. If the board replaced with new one, your unit will back to normal again. Also, consider bad solder joints in that area, it will do the same symptom like what you've encountered right now. Find it first and re-solder. If you don't have necessary tools and test instrument and can't do the job yourself, I would advise you to look for a qualified technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
