When cleaning the front of your tv do you spray glass cleaner on the glass? Many time I have seen glass cleaner that has dripped down onto the pc board, contols like power, vol, and channel control are under the tube and there is nothing to protect it from liquid, if it has not eaten the componets from Corsosion there may be a chance that you may be able to clean with flux remover or tuner cleaner. Be very careful when using these cleaners because they can eat plastic.

If I read your post correctly it sounds like, the remote no longer works the volume or power for the TV set. If this is correct follow the steps below for a Power Scan. If this is not the issue or the steps don't work feel free to contact me and we will sort this out! Power Scan 1.) Hold down the clear "TV" button on the remote for four seconds, then press 500 pound ( #) 2.) Hold down the clear "TV" button on the remote for four seconds, press the big power button once. 3.) Press the channel up button once per second until the TV turns off then press pound (#).
Try several functions Mute Volume and Power to make sure the remote works properly then press "SAT".
Unfortunately, the Power Supply has spat the dummy out. It is giving enough power to light the LED but not enough to run the set. To replace it will probably cost more than buying a new set. But ask around your local repairers for a price before you make any decisions...
The color problems are caused by cracked/broken solder joints on the circuit that controls the display.
Usually this is located at the back of the tube on a small circuit board. Your description suggests that only the blue signal circuit is intact. I suggest these joints be resoldered for more strength.
It's a possibility that another IC senses this problem (or another one) and then shuts down the system.
Resolder those joints and see what happens.
