The problem as you describe it usually means a vertical problem for a standard TV and the solution is either to resolder the pins of the IC or to replace it. I am not familiar with the board layout of your model, but there should be a small flat IC attached to a heat sinh with about 9-11 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC.

Please note that there are potentially dangerous high voltages present even with the set unplugged.

How do I hook up my dvd/vcr to the tv


On the back of the cinavision you have two groups of sockets. The yellow socket under Video out is picture. Red and white is sound. Connect them to the TV's yellow red white sockets marked Video In 1. This connection will give you picture and sound from either the VCR or the DVD deck.

There's a better picture quality available for DVDs only from the Component video out sockets (green red blue). Next to them is another set of audio sockets (red white). Connect all five sockets to the TV's input number 2. The colours match up. The picture from Component will be clearer and sharper.

On your Sharp TV remote, select Video 1 to watch VCR, and Video 2 to watch DVDs.

Black and white picture with red lines vibrating with sound.


More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

Hi.. Mine is a sansui tv and I bought it 3 years back. Now it is showing a horizontal line on the screen. Sound is fine but I can't see the picture, I just see one white horizontal line on tv...


The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

Black Screen with a white line through the middle of screen.


The Flyback i'e the circuit board on the back of the tube as thus malfuctioned and give you this white line with sound.. If you did not have sound we would be discussing the PSU "power supply unit" This fly back for a 27 inch will run $105 plus tax.. The installation thereof would be done by a technition witch will charge 15 to 20 per hour.. Okay here is the sad part you can recycle this TV and get a flat panel for much cheaper then it would take to repair this unit "i am just telling you the truth" But do not shoot the messangero n this one, since I did tell you you're proble could you leave a rating?

Tv beginning to flash green with horizontal white lines


From your description it sounds like a bad picture tube. The lines are called retrace lines. There is a small chance that a component on the small board that connects to the neck of the tube may be bad. Without model number information it is very difficult so say further. Some picture tubes can be re-jeuvenated with the appropriate machine ( at a TV repar shop)
If you feel adventurous and are careful you might try GENTLY tapping the neck of the tube and see if picture improves/goes out. If the tapping does change the picture it is definitely the tube

Sound but no picture


A white like across the screen means that the vertical circuit has stopped working. Look for a small fuse that looks like a resistor near the vertical output IC, replace that fuse if open and resolder the pins on the vertical output IC.
