Question about Olevia LT37HVS 37 in. LCD HDTV
After a power outage with the TV on, my Olevia LCD will not turn on. The has happened twice. The blue Olevia light will come on, but the TV will not. This happened once before last month and after 3 days, the TV started working as normal. Now, the 2nd time around, I'm waiting for 3 more days to see if it will start working again. Does anyone know if these TV's have some sort of reset button or internal protection that can be overridden. Fingers are crossed that the TV starts working again in 3 days. If it does, I'll be buying a UPS for the TV immediately.
SOURCE: Olevia 42"
@givemhall: I had this happen to my 42" after I moved. It turns out that when we were carrying the TV, the power button got pressed down too hard (it's right near where you would put your hand to lift the set) and it was stuck in the ON position. We took the TV apart and fixed the switch, then the TV worked like a charm. It's about an 45 minutes worth of tear-down, but we were ecstatic when it came back to life. Hope this helps you!

As suggested in another post, w2power has provided this solution. It is the only thing that has worked for me thus far. While it is a pain, I can at least consistently get my set to turn-on when using this USB cable method with logged-in PC attached to Olevia's service port (I have the 23" version)
"I think this model has a timer on it, it seems to go when the warranty runs out, not proven but Mine went out about a month ago. My only fix is to plug my tv (via the service port which is COVERED) to the usb port on my computer using my BlackBerry usb cable, in other words the Mini USB. Seemingly I must be logged on to do so and wait for the Chime form my pc, a balloon will pop up for new hardware not recognized (vista) then press the power button and then it turns on, unplug the usb cable and make sure the source is set to tv / video or else it will power back off and you will have to start all over. Theres NOT A PERMANENT fix yet but this is what I do every time I want to use the TV, I have a laptop so I use it as the Monitor just to watch movies. If you have a desktop I recommend keeping the cable handy BUT DO NOT LEAVE THE USB CABLE IN FOR LONG USES. THE SERVICE PORT IS COVERED FOR A REASON!!!

you have a broken inverter board. I have a LT30HV, and it had the same problem. The inverter board supplies power to the backlight. Swap it out with a good one, and you're back in business.
To test, take a bright flashlight and point it at the screen just an inch or so off the surface. If you can see your picture, then you have a blown inverter.
it may not be worth fixing it. Wait for a good sale on a new one. My inverter cost about 150, and it was a remanufactured part. Not as good as the original part as it flickers just a tad. I had to take the entire TV apart, with pieces literally everywhere. My cats loved it.

> I heard they were restructuring their company or something.
There has been a change ownership from Syntax-Brillian to Olevia International Group.
Details of Olevia brand
Unfortunately for all of us (we have 747i) service seems very poor and the failure mode you describe doesn't give me any clues despite 40+ years of service experience.
Ours is still 100% but I now suspect our trouble will come.

Olevia has problems with the power supplies. Best solution is to remove the back of the TV. On the 542 it is about twenty number 1 phillips head screws. locate the power supply connectors check the board for the voltages, clearly marked on the PCB. Continue to check the voltages by powering on the Television. all voltages should be within its described range. If a voltage is low or nonexistent, the power supply is bad, usually a bad capacitor.
There are three series of caps, on the low voltage side it is 16 volt, next 24 volt and finally 36 volt (these are just max ratings.
which ever power that was found low the cap would be near that voltage output connector.
next step is to remove the board and replace the capacitor, using a soldering iron and making sure to solder with no slop.
with the board on an insulated (nonconductive surface connect the board to the televion. Check voltages and if no other voltage issues reassemble.
