The picture flashing that you are experiencing is likely due to a defective IC on the main PWB, IC802 is the one I would expect. This part is not available in the US that I know of and if it were, you would need a rebuilding service to replace it. The board that it is mounted on also is not available AFAIK.

I have and olevia 26 in tv..when i try powering the TV on.. shows blue input screen for a split second and picture goes out to black screen..not sure if still have sound but...i hit power button again blue...


There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
Cpacitors are less than a buck a piece typically if you order online from a place like www.digikey.com plus shipping, and they usually arrive next business day.

Tv will not turn on


Get a power extension cord to connect your TV power to another (zone)room by using a different outlet and see if that is still does it.
Remember when you unplug the TV,you want to give it 15-20 seconds first .
If it still have the same issue,i hope you have the warranty,you are going to need it for repair.

TV turns on for a split second then back to standyby


i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors
