When I turned the tv on only vertical lines appeared

Hi. Without a photo is hard to say with sure. But probably you have a lcd or led tv, so verticals lines is a screem defect with sure and unfurtunatly this doesn't repairable.
The solution will be replace the display screen, but I don't think it's worth it.

bad Q box, need tech to replace

Go to the last page of troubleshooting in the manual and perform the system reset procedure. Basically hold the Wega "arrow up" as you manually switch the TV off. It will automatically switch back on and reset. I had only vertical colored lines on the screen, with audio but no response to any remote control functions. The rest worked perfectly.

I guess I have to pay money for a solution, which is not what this website says. The only answer I got was pay money and we'll tell you. Is that true/

I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.

this is a malfunction vertical deflection block of your TV-set .please contact the nearest repair shop.do not turn it on until then,please.

Definately a video processing problem and it may need a logic board it is called. Does the set work fine if you feed component into set to bypass all that? Let me know. GURU JAY
