My TV keeps dimming even when I have no devices connected to it
I have a Panasonic LCD TV. Model TC-L55E50. About a month ago it started dimming towards the top and right side of the tv. I removed all devices and even the message that tells me No signal. Ensure an external device….. is dimming. Is it the T-Con board or the Inverter. If I turn the tv on I see the backlight with no problems
Is dit een goede vraag?
