Black lines in tv

Most likely there are electrolytic capacitors in the power supply, video path, and scan amplifiers that are starting to fail from age. This is common in many of these sets. In consideration of the age of the set, this may not be worth having it serviced.

Scattered black lines appear then screen gos black, but still have good volume

Hello 4fiddy,

You have actually diagnosed your own problem, Let me explain; the line "I can slap the left side of the tv and picture will almost always come back on" This indicate some form of poor connection (cold solder joint). If you have a soldering iron, solder (circuit type not pipe type), and a multimeter. Use the soldering iron and solder to redo the cold solder joints , and then test it (the connection) with the multimeter.

I hope this helps

Thank you,

Sony 51" rear project tv

Click here to find information on how to fix your TV. Make sure that you turn the screen control slightly counterclockwise until you see the lines disappear.
I would suggest to put a mark where the original position is, just in case you have to go back to the default position.
Good Luck.

51 big screen apex tv, convergence or verticle IC?

If the lines are thin and close together running horizontally, it may be the vertical driver, but that usually takes out the resistor and sometimes the diode in the B+ for the vert. Also you must replace the caps that caused the problem in the first place.
