Hi my 48" ue48h6200 tv was working fine u til last night. I have an external hard drive connected to record tv into and it kept freezing so switched the tv off.
When it turned back on it shows the smart tv logo then goes to a blank screen. Back light is still on... when you try to do anything 3 lights blink at the sensor then pause and repeat. Within 30 seconds the tv switches off.
It' connected direct to plug socket in wall. Nothing is plugged in to the back currently just power cable.
Any suggestions? A repair man is looking tomorrow but it could be 2 days before I get any answers.
