Question about Projection Televisions
I RECEIVED ASSISTANCE AND WAS TOLD THE FOLLOWING-
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.
MY QUESTION NOW IS WHERE IS CRT FILAMENT CONNECTIONS & THE PICTURE TUBE SOCKET?
MODEL NO. A56M91W5
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
