My sanyo tv has vertical lines for 30 to 50 minutes and gradually clears up. Any ideas what the problem is?

Hi,

Disconnect the power supply for few minutes and then turn it on. If the problem persists, it would confirm an internal problem and needs repair. This is highly suggestive of a problem with main board. Other probabilities could be T conn board, panel or other internal component.Unfortunately,there is no simple option to determine the exact fault without opening the TV. If needed to speculate, i would go with mainboard as this is a common problem on most of the TV's.You need to either call a professional on site to fix this or you need to open the TV to investigate and replace the faulty component.

If you have any prior electronics repair experience, and wanted to repair it, revert and i would be glad to follow up from there.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
