Olevia yesterday, there was a power outage in my condo building.  Since, my display will not display.  It is hooked up through my stereo so I hear the tv (direct tv), can change channels and hear everything through the stero but the monitor will not turn on. The little red light comes on indicating power is going to the until, but nothing else.  I have checked all connections, reset power, turned off and unplugged in back of monitor etc to no avail...it's only 2 years old...is there anyway to see if it is toast or am I missing something?  Thanks so much for your help.  Colette  305-807-8539

You need to check your SAFETY beam
the two little black boxes on both sides of your garage door
(typically about ONE foot above the floor level...
should be showing a green & a red light when pointed
DIRECTLY at each-other )).

Red = unbroken beam.
Green = Power on.

You can HOLD down the WIRED button
to override this SAFETY feature....

Do check your owners manual.

it is possible you OUTAGE fried your electronics
but the most common cause is these BOXES are't
properly aligned.

Testing and repairing Olevia 237-T11:

Hope this helps!

Check power outlet. Connect TV to a different power outlet. Switch off TV manually, switch off power input, remove plug and cool it off for 48 hours and retry. If problem persists, it might need attention by a qualified service technician.

Of course it will work with any standard stereo RCA source (which just about everything STILL has) but it won't work directly with any digital sources. It has NO digital interfaces.

You didn't include your model number so an exact description of the menu system isn't possible. Look the menu offerings over and for the term 'Source' or 'Input.' I suspect the power outage may have returned the set to factory defaults and that could be anything so the set is likely not looking for the signal where it should.

Surge protectors are meant to trip whenever an outage occurs to prevent component damage. If possible remove back panel and check if any fuses were burned. If all looks normal then your component is most likely fried.

its posible a lose connection. on lcd's is a common failure. during transport. by sea its almost imposible to avoid , some contamination. need to be serviced , cleaned or replaced the defective component. tell me more about ,does it has sound?
