Syntax Olevia flat screen tv video goes off then on

Likely the main board and most of these sets there are few or no boards available.

problem with keyboard on set front or side===likely defective switches under the plastic buttons.

If the tv is infact turning on eventhough the power light isnt, its the bulb for the powerlight itself

The tv have a Tuner board problems,this is the board,that take in the broscasting signal cable.Tries unplug,replug about an hour later.The tv should reset it self and work.Not than tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.

Is this an IC? Do you have the part designator? Your power supply check out OK?

seems like the main-board is having some issues.. the tv's main-board will have to be replace or repair..

Since the manuf. when out of buss.. the only way to get that fix is thru the 3rd party repair center called Amergence Technology in witch they service all Olevia Televisions..

There number is 866-965-3842 im sure they could give you an estimate on the repair cost for you.

The electronics are known to go bad with these TV's, and I'm looking to buy someone's junk TV that has a good screen, rather than have to throw it out.   
(So if anyone is out there with a 532-B12 that isn't working, send me a message!)
Yours might be worth fixing - however I know sadly that parts are nearly impossible to get for these TV's, and the manufacturer is virtually impossible to contact.
If you DO manage to contact anyone (manufacturer or otherwise) who can source or supply parts, PLEASE do let me know - it's been nearly impossible for me, and I want to replace my cracked screen in my TV.
If you can't, please let me know - I'll gladly give you a few bucks at least to salvage the screen from your TV, to transplant into mine, rather than turning it into junk on your curb.

Finally recieved an email from syntax olevia customer support after 1 month. a standard desktop computer power cord is all you need for your Olevia LT26HVE flat screen. We lost ours in a move and FINALLY have it up and running again...for only 9 bucks at RadioShack!

OLEVIA SAYS UNPLUG ALL (ELECTRIC, CABLE ECT. FOR 2 HOURS THEN REPLUG IN, THIS WILL RESET POWER PROGRAMMING0

I just had this same problem over the weekend. Is your TV hooked up via HDMI?? Mine was and i've been having problems with the tv image shrinking whenever i turn on the tv, so i would have to change the channel 1 or 2 times for the image to come up normally. On Saturday I went to change the channel and then all of a sudden I hearld this loud pop and when the image came on it was just a sky blue screen, I couldnt see anything, but I could hear the channel. So I disconnected the HDMI and hooked up the tv with component cables I had and now it works fine. I ordered a new HDMI cable just to see if it will work again. If not, i'm calling Olevia.
