I am sure konka made this misakai 32 inch tv. I could send you schematics there not helping me. Tv wont power up. Relay is not picking up. I have 170 volts at bridge cant figure out what turns on the relay, half the components shown on the print are not on the board. I have basic electronics and weak blue print reading skills but I am determined to fix it. Any advice.

Re: chassis kp2771uy, wont power up
If you have a switching power supply then you may have a problem with it. Also maybe a short on its load.
The relay may be used only to de-magnetize the pic tube.
If the set is also controlled by a micro processor then the stand -by voltage could be missing.
so many possibilities that it's difficult to tell exactly what is happening.
These are only a few things that may be wrong.

It might help someone to help solve your problem is you state what you're trying to do. Most tv's just plug into a standard ac wall jack. Are you taking it to Europe or bringing it to America? Most color lcd tv's pull about 150 watts (or less)
It's really not quite enough to go on and could be any of the following; Bad FBT (flyback transformer), R216 in the ABL circuit. (Auto blanking limiter); D404 in the Hv circuit or the HOT (horizontal output transistor) at Q404... I'd start there first and if those test okay then I will dig out the schematics and send you the service manual.
Do you get any relay click when you press power button? That's a TAC0116 chassis and prone to any or all of the above.
Hope this helps!
