You cant. The fluid and other parts are not available anymore. This TV is too old to repair reasonably. To replace the tubes would be over a $1000 if you can even find them.

It is normal for it to flash for about 10 minutes after turning it off, while it cools down the bulb. You're not supposed to try turning it on during this time. If it is flashing constantly, it is telling you the bulb needs replacing.

The common cause of the 5 blinks on this model is one of the CRT boards on the tubes, or the drive voltage from the A board is not correct.

KP-43HT20 has 2 tuners, one is main (TU2) and 2nd is called sub tuner (TU1). Both tuners are mounted on A board located on right side of TV.
In my opinion, main tuner (TU2) is not working and causing No Signal message.
Let me know if you want to repair tv by yourself.to provide you more technical info.

this model is prone to this problem--bad picture tubes.

I have a way for you to attempt to adjust around it.

If green appears to bleed out of objects then it's probably the saturation level is to high. If that doesn't work you can try changing the Hue setting more towards red and away from green.
If neither works and you don't have a warranty I would call your a local TV repair company.

The model listed and several near it had issues with the 3 picture tubes--it may be possible to adjust the red screen down---not too hard to do
