Zenith A25A23W tv - Powers up - Black screen, no sound
I was given a Zenith A25A23W tv. It powers on, but has a black screen and no sound. Tried both cable and video in rca connectors - no luck. All menu selections/choices do appear on screen in monochrome format and I can make menu changes (makes me think the CRT is getting power). When I perform auto channel scan, it comes back requesting to check cable connections!
Can anyone provide any solutions or recommendations?

Hello, Connet the output of the cable box to the DVD player and the TV out output of the DVD player to the TV (TV must be tuned to Channel 0, Chanel 3 or 4). You should be able to use the remote to switch between the DVD signal and the cable signal.
Is the TV connected to cable? Is there a cable box? Is it connected to a satellite box? How is the signal connecting to the TV - the F connector, the red,white,yellow, red,white,,s-video or component RCA jacks? If you can see the onscreen menu then it usually indicates that the TV is working fine and the problem is with the signal into the TV.
Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck

If your t.v.has built-in blue screen when there is no signal, then the DVD may have been accidentally switched to progressive scan mode, or defaults to that setting if new. If your T.V. is not capable of displaying in progressive scan mode, you will just get a blue screen. If you have an older tv, without blue screen, then connect it to that, and if you get a black and white split screen when you turn on the DVD, then progressive scan is the problem. Check the manual for the DVD player for the procedure to get out of that mode, and it should then work. If you still have no video, and you are using the yellow composite video jack on the back of your DVD player, then it must be brought in for service.
