what causes vertical lines in my sanyo 42" tv

Hi. I'm Steve. I'm sorry to hear about your TV. I will try my best to give you a precise and accurate answer.

Some questions for you. Please try and address them all so that I may help you quicker.

1. Grab the Sanyo TV remote and press menu. Are the lines in the way of the menu display? Or are the lines behind the menu display.

2. What do you have connected to the TV? Cable box? Something else?

Let me know.

in the way of the menu box hooked up to a cable box

No. I want you to forget the cable box and pull up one of the Sanyo's own internal menus.

Like I said, on the Sanyo remote, press MENU.

the lines are through the menu

Ok. You have a problem with the TCON board or the actual LCD panel.

The TCON is actually part of the panel but often available separately.

Is this something you can do your self or are you looking for a rough price to fix?

I can help you either way.

Let me know.

looking for a price to fix and the name of the parts needed

Here is the TCON: http://www.ebay.com/itm/SANYO-DP42848-T-CON-CONTROL-BOARD-T420HW01-V2-/170906131863?pt=US_TV_Boards_Parts_Components&hash=item27cacc9d97

Please remember that this may not fix the problem if the actual screen is bad.

There is a basic test for this. You would need to remove the back from the TV.

To have a tech fix this for you (the TCON) will run you about $200 assuming that you take the TV to him. More if he comes to your home.

Let me know if I can help you further.
