Hello..Toshiba 51HC85, 2005 model. Turn on TV and verticle wavy lines appear until TV is warmed up completely. After warm up the picture is great again. Any ideas?


I've had the same problem for about the last 6 months. My workaround which was to leave the tv on 24 7 and just turn off the TWC service box. But now the symptoms are vertical dark lines going all the way across screen. My guess is that it will cost more to fix than worth it. I paid @$2000 for it new in 2004. Technology has gotten better so I may just go out and get a Samsumg for considerably less and be way better off. None of Toshiba's products had done well for me. 2 laptops, 3 tvs, etc. have taught me this.

When I run the Touch Focus , it ends Touch Focus Error, and the Red Verticle line does not move , the Horizontal is bent .. now tv is fuzzy?


This is a 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 charge between $200-$300

That's a good one!

If you're using component video cables, make sure they are good and tight. If it's composite video or S-video inputs, you will likely need service.

I have the exact same problem a month ago. I replaced the two STK392-110 ICs with the STK392-110T adn everything went back to the way it was.

51 big screen apex tv, convergence or verticle IC?


If the lines are thin and close together running horizontally, it may be the vertical driver, but that usually takes out the resistor and sometimes the diode in the B+ for the vert. Also you must replace the caps that caused the problem in the first place.
