I have an old KV-27FS16 which started to have problems powering up. Eventually it didn't power up at all and blinked 4 times in a loop. Since it is old I took a look inside. What I read so far points to aD-board problem. After a while I forgot that I took the D-board outand I power it up and it did. I connected an antenna and I can seechannels.
What is the function of the D-board? Do I really need it?

The chirping is the power supply trying to start. This is not a repair that I would recommend a novice attempt. PLease have this unti serviced. Expect a parts cost in the $20-$40 range for power supply caps.
we have the same porblem. We just unplug ours and wait a couple of weeks while watching another tv plug and un plug it will eventually come on then we dont turn it off again it only goes off if the power goes off.
The popping is a bad indicator, something failed catostrophically. This would not be an easy repair, I wouldnt recommend opening the tv, I would take it to a repair shop as it will require some electronic troubleshooting at the component level. Since this tv has a tube most likely there is only two boards, a main board and a kneck board, even replacing the boards is dangerous without knowing the safety precautions.
there is an apparatu use to degauss the color of tv, usually technician has.but ,if you don't have that apparatu, you can use the magnet of the speaker by placing it nearer the screen and moving it from left to right...
