Question about Projection Televisions
Sometimes unable to change channel, increase volume, basically can't do anything except watch the channel that's tuned in at the time. CaN'T EVEN POWER OFF - Only solution is switching off and on at the mains
the liquid from the cleaner dripped down to the switch it sounds like and the only way to fix this if its not to late is to pull out the Printed curcuit board and clean the switches and the pcb in the front of the set and get all the liquid cleaner out and off the board. now you wanna clean the board with something without lubercante like a tuner wash from chemtronics or something like that. I've told peeps a million times , when you clean off a crt face apply the cleaner or spray on the cleaning cloth directly first. Never ever spray on a picture tube face as this will happen eventually if you do.. Good Luck

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.
I hope this helps,
