Sharp 25" tv unknown model (no av in)

If the AVC System is switched on but it does not appear to be operating correctly, it may need resetting. In this case, press RESET, shown in the diagram, lightly with the end of a ballpoint pen or other pointed object. This will reset the System as shown below. • AV MODE resets to STANDARD • TV channel returns to initial channel setting (Air:2ch, Cable:1 or 2ch) • Twin picture resets to normal • Audio setting initializes • Dolby virtual resets to Off • Image position initializes

you can hook it up thru av input..what i mean is the red white and yellow wires hook wires into the OUTPUT on box and the input on tv then change tv to the input u hooked them to..for example if u hooked them into av1 then turn tv to av or hiy input on remote

U have to trouble shoot for leaky capacitors in the video and horizontal circuits/Areas

Check to make sure it is on either the AV 1 or AV 2 channel

Good day.
Try to check the crt socket. Also, check for the loose contacts along the Chroma IC. Like wise, there is a screen adjustment on the rear portion of the flyback. Try to adjust the screen.

Response is highly appreciated.

Solder any / all bad connects, check capacitors,esp.horiz drive.

Check horiz output transistor and solder any / all bad connects,
Check fuses.......T.

If the screen is part of your laptop/notebook/netbook, try to connect an external monitor to the VGA port, to see if the video-card in your computer is generating the "weirdness".

If the screen is an external monitor, try connecting it to a different computer, to see if the "weirdness" follows to the new computer,
implying that the monitor is faulty. Also, connect a diffferent monitor to your computer, to see if the video-card is causing the problem.
