The screen is black. I have sound but no picture.


Hello,
If everything else works - there is sound and high voltage (static on the screen) - but there is no picture (including no on-screen menus), this limits the likely area of problems is the video output circuitry or CRT filament connections. Check to see if the CRT filaments are glowing. If they are not glowing, check for bad soldering on the CRT neck board and around the flyback transformer.

Where the picture is erratic - coming and going entirely or changing brightness suddenly, with power off, remove the picture tube socket (carefully!) and clean the pins with fine sandpaper and use contact cleaner on the socket. This source of bad connections can result in a variety of erratic symptoms. Check for bad solder connections on the CRT neck board.

When u push the power button the tv tries to turn on, makes 3 switch noises and then the power turns off


this is somtimes a bad power supply or fuse if you have sound it likly and no picture usaly a fuse put this seems pretty much like a power supply issue this regulates power from the wall to each component of the tv like the picture and the souns amp

NO PICTURE AFTER FEW MINUTES/DARK PICTURE/ERRATIC/NO MENU VISSIBLE


Most projections have a removable speaker cover on the front under the screen. Then there is an access panel that you remove the CRT sockets are the circuit boards attached to the CRTs
