My RCA projection tv makes a loud buzzing, humming noise. Does as soon as turned on even before picture comes on, does not stop till tv is turned off.

buzzing noise is cause by small electrical arc inside the unit or a problem in your audio circuit.if you can open the unit up and check if its an electrical arc.

Won't power on

my d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up.  latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.

Do we need a new TV?

I dont think this problem can be fixed without solder work or part replacement of convergence section. Its no just matter of fuse. You should get repair facility from concern service center because TV has dangrous voltages inside and qualified person knows how to deal with TV.

This problem is commonly refered to as a CONVERGENCE problem. Question 1 do you have convergence seting in setup menu...if you do NOT it could be a special small fuse. 2 if you go into setup then convergence. then can you move crosshairs in setup. Since you have a arcing picture this indicates convergence power supply which has to be replaced or repaired,
