Panasonic TV tx-48cx400e led backlight issue
Hello all,
I have Panasonic TV tx-48cx400e led. The TV turns on normally and all is great for hours… however the backlight goes off and then if i turn the TV off and on again, the backlight works for an hours, or 5 min, or sometimes 1 min at a time!!
Sometimes the TV works perfectly for the whole day!! and other times the backlight can turn off after 30min of use! the timings are random.
I will try factory resetting the TV, but does anyone have a certain cause and solution or fix before I take it to repair man ?
Thanks a lot for any help!
Happy Holidays
