If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Yes they are bankrupt, and they did see repair services out to third party vendor- this appears to be phone support at $25 per 1/2 hour.

email response from service inquiry....

Thank you for contacting us. My name is Ravin and I understand that you have called in today for further troubleshooting but you were offered a paid service instead. Based on the information provided, I believe that the following steps should effectively resolve the issue:

I am sorry to inform you that, Syntax-Brillian, the manufacturer of the Olevia Brand, has declared chapter 11 bankruptcy and has ceased all operations. Because Syntax-Brillian is no longer in business the warranty for your product is void.

Amergence Technology, a 3rd party repair company, can offer paid repair services for your television and a paid service for further troubleshooting. Since Syntax-Brillian went out of business, Amergence is offering repair services to owners of Olevia HDTV's.

If you have any further questions or concerns, please do not hesitate to contact our Support Team at 866-965-3842 Monday through Friday between 7.00am 5.00pm PST

Sincerely,
Ravin

There remains only the fluorescent back light tube(s) or the inverter that supplies high voltage for it (them). If you had no warning flickering, I would look for the inverter board.

How to adjust va,vs,vr set-up and set-down?


If its an LCD TV as stated (42LC2D), you do not adjust Va/Vs etc. this is only done on Plasma TV's especially after replacing either the power supply or the screen itself.
