Sounds very much like a main power supply that needs a 'kick' to start up. This is often caused by the loss of value of a capacitor in the power supply, one that handles feedback to start the supply initially and carries the signal to shut it down in case of a circuit fault in one of the areas the supply services. Inadequate feedback will make the supply unable to start properly and more likely to shut down even though no fault condition exists. If I'm right, it will get worse and searching for the problem requires an instrument not found in the average home; a capacitance meter with loss measuring capabilities.

Cant switch on my Irion TV


Maybe things will improve if you leave your TV permanently receiving power from the wall switch and do the actual on-off switching at the TV. Your Orion TV draws standby power even when it is off. When you flip the wall switch off there is no standby power

Receiver keeps going to standby


I don't know about the newer receivers but this sounds like an arching OFF/ON power switch that was a problem on Pioneer receivers years ago. I would bypass the switch and see what happens.

1. Unplug unit from wall.
2. Jumper two wires going to off/on switch using alligator clip with insulated boots on clips.
3. Plug amplifier into disconnected circuit breaker/fuse protected AC strip.
4. Plug AC strip into wall outlet, turn AC strip switch ON and see if problem disappears.

I have a 36'olevia HDTV.......it has a detachable power cord and it also has a power switch in back. When I plugged it into the wall,turned on the power switch, and pressed the power button, I got no


The light is likely the standby light if it is on when set is off and goes out when set turned on or changes color when set comes on.

The fact the light is on should rule OUT the main fuse for the set, most likely the problem is the power supply itself inside the set

The Standby supply is part of the main power supply and when set is plugged in and off it runs 7/24.

Have you had problems where the set was "hard to turn on" or you had to try to turn it on several times before it would stay on?

'standby' mode and akb error number


AKB 66 in self diagnostic test means...TV goes to standby (shut-off) for AKB problem 66 times. AKB is White-Balance signal and it is not proper or maintained in your TV. So error signal produced and TV goes to shut-down state.
Regardnig Standby button, its available on remote only. If you push TV Power switch, TV will switch ON, push it again to OFF TV. Power Button on remote set TV in standby status and you dont need to push power button of TV itself.

TV Switches itself back to standby mode continuously


if your remote is ok then this is due to power supply failure in your tv. either it is loose in oscillator ckt in switching section or it has failed. if not tech person call tech to fix it. not a major problem.
