Question about Televison & Video
Picture has been fine, surround sound works fine, it is louder in DVD than TV/VCR mode but regular TV sound is intermittent. I have tried compressed air, taking the back of checking connections to the speaker...i know nothing when it comes to tearin' into diodes & transitors. i need diagrams for that.

SOURCE: TV picture flickers
If your DVD player is separate from your tv, you might have a loose cable plug or connection. Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too. Stargazer

SOURCE: TV will not stay on
when you turn the TV off do you see abreif white line acroos the screen and do you feel the static on the fornt of the set when it comes on? If so
This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.
