Good day, rios_4435;
Double check all, I said ALL cables, check the soldering performance on the IC's. Look very closely for bridged solder joints.You did something again double all of your work, make sure you installed correct parts, maybe new parts defective.
Good Luck, big IRISH.

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 STK series and some of the resistors around because its already gone bad.If these parts 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.
