Question about Televison & Video
Pretty sure the reason for my Technika 22-700 standy light is flashing is due to a blown diode and/or resister, reading http://www.normsweb.com/tektips/technika.shtml it says to replace diode D102 and resistor R110 but this guide does not match up with my model of Technika TV, tried searching web but can not find any links to my model of Technika ????
How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

Hi brendafoud, have you had this fixed as mine is the same and has been for months. It happened just after the warranty had ran out(typical). Bought from ebay and the people I got it from are not very helpfull. Have you got yours fixed yet?

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 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 5 mins, then try.
If you aren't tech savvy, this unit needs to go in for repair.
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).
Most of the caps that go are 10V 1000uF or 3300uF.
I found some great videos of the procedure (for different brand, but 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.
