The problem is in the standby power supply. the standby power supply generates the 9 volts and the 5 volts requird by the tv. If you measure the 9 volts source, with only the red light on, the correct voltage is 9 volts. However if the 9 volt measures 6.5 to 7 volts it is too low and the startup relays cannot operate. My set is a model 42FR9954/17S. In this set if capicator, 2603, is heated the voltage climbs to 9 volts and the relays work. If cold air is applied to the capicator the relays fail to operate. Replace capacitor 2503 and the problen is fixed. This capicator is: 47 Ufd, rated @ 450 volts, and is 20%.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

SOURCE: Orange Led syndrom
I found the following solution on internet:
Fault: Unit held down with only orange LED lit
Remedy: Remove the main metal screen cover from main board and check the input
voltage on to the main 3.3Volt regulator IC202 it should be bang on more or less
5Volts, if not replace capacitors C905 330uf 10v C908 470uf 10v both are to be
found in the main power supply section.
Unfortunately I'm not very technical so now I will need to find someone to do this for me...

Hi, l had the same problem. HAD !!
l bought a universal remote control (5 euro), but unfortunetly no codes for Acer in it.
Then l did the setting up by auto search and YES : there was a code. But, wheeehh, it did not work.
A little bit sad l took the Acer control and guess what: it worked again!!!!! l guess the TV had a total reset, and l use only the Acer remote control now.....
Female and blond!
