The model number is *****
We bought it 2.5 years ago. The problems started yesterday. The TV was left in standby mode and when it was switched on the problem began.
The green and orange light are blinking simultaneously and continuously with no repeating pattern to the blinks.
We tried the above manoeuvre four times as requested. Each time the green light came on statically for about three seconds then the orange light came on and both lights started blinking as before.
Thanks for your help. At least we now know what we are dealing with.
