Re: GE Model #25GT511 Power on, no picture or sound
The question I have is if the tv stays on but with no pix or sound,we have a way to check,if you place your forearm in the face of the picture tube and the hair in your arm stands up it means you have the high voltage needed to light up the tube but something else is missing like the screen voltage or it has a loose conection in the crt board,if the hair in your arm does not react to static then we are missing the high voltage and the problem might be more involved and related to the horizontal circuit not creating the high voltage needed.If you are familiar with tv service you have a few places to check but if you are not to familiar play it safe and call for assistance from a professional servicer.Let Us know how it goes please.

Note: most remotes allow you to find the code by manually turning the TV (or other device) on first, then press the appropriate button (cable, DVD, surround, etc) then setting the the remote in the "program" mode, then keep pushing the "off/power" button until the TV (or other device) turns off, at that point the code is set.
Make sure your menu settings are correct audio outputs may have a setting for digital or analog sound output check that these are set up to analog or stereo output .Also try hooking the sound up direct to a stereo system or amp to be sure you have output! Also you may not be able to get your sound thru the convertor box!! Because the convertor is a reciever of digital signals not a line amp. for audio !! Hope this helps11 AAAAAAAAAAAAAE!!!!

FIRST!!! Make sure you have the coax or AV cables plugged into jacks marked out on the machine.....then....
*If you have it hooked up with a Coax cable, you should immediately have picture and sound when you turn it on. Make sure you have a dvd/vhs running and switch between channel 3 and 4. if this doesn't work, make sure that you have the cable connected to the one marked 'in' or 'cable in' or 'ant in'. then retry the previous steps.
*If you have it hooked up through A/V cables (Red/Yellow/White), make sure you have them all connected to the same set of jacks. They should be labeled Aux 1 or something similar and are generally surrounded by a box molded into the TV's plastic casing. You will then have to use the TV remote to switch TV/Video settings until you get to the one that matches the Aux jacks you have it plugged into. Again...make sure a dvd or vhs is running and keep flipping until you find a picture.
You may have a connection problem, particularly check the cable which goes from VCR output to TV input.
The RF signal is carried on the center conductor of the coax cable. If you look at the end of the coax, you will see this center wire. If this wire is substantially recessed (too short) or bent over, then it might not make contact with the connection of the VCR tuner out or TV in. Try a different interconnection cable. If problems still remain with this substitute cable, when you have things all hooked up, try moving the cabling from side to side, and see if the picture quality changes substantially.
Another possibility is the tuner in the VCR is defective. If so, repair is not economical- replace the VCR.
most tv/vcr combo has only one power supply source which is located in the vcr unit. u have a power supply circuit problem. try to check the rectifier, filter capacitor and the regulator ic/transistor. good luck!
