Re: Sharp LC-70LE632U 2-5 error
hi did you try to clean the connections arround the lcd panel the little flexible ribbon cables and the ones from the t-con ? be carefull verry fragile unplug tv before and make sure the are well in place take pictures before so you have a reference .
if the screen is not craked that could be the problem especially if it was not in a smoke free environement .Leave a comment:
