Also on these sets, the vertical I.C. gets cold solder joints.
resolder them before replacing the I.C.

You must change the capacitors around the IC before replacement. usually 100uf is the biggest failure, It may have also burned a 1 ohm or so resistor

You lost your vertical sweep. most likely the vertical output IC or a power supply source is the problem.

Sound only


Means the TV is foobar. How do you connect it? TV Aerial, cable, RCA, SCART, S-Video, Composite, HDMA. Checked your cables, made sure they are all snug? Made sure your source (eg DVD player) is OK?

Hooking up a DVD player to a Quasar TV/VCR Combo


Hi,

Yes, for a workaround. The adapter would be 2 RCA female to 1 RCA male. You have to connect both the red and white to the female RCAs and use the male to connect to the TV's Audio INput. The yellow goes to the video. There should be no negative technical effect other than lost of stereo quality. The audio output of the DVD is line level and could normally tolerate this condition.

The correct method is to use a simple line level audio mixer and mix the L& R audio signal to produce a mono signal or to use a stereo amplifier for the sound output.

Hope this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

DVD PLAYS GREAT, TV AND VCR PLAY IN BLK-WHT W/NO SOUND


You have your DVD connected to your VCR, which is then connected to your TV, right? The problem is Macrovision. It's designed to prevent you from connecting your DVD player to your VCR, so that you can't make duplicates of copyrighted movies. It's a real pain in the neck. Try turning the DVD player off - or better yet, unplugging its power cord (as some DVD players are always in a standby mode, even when turned off). If that fixes the problem, then you need to reconnect your DVD player directly to the TV, not wired through the VCR. If your DVD player isn't wired through the VCR, are you using some kind of wire splitter (one cable branches into two) to connect both the DVD player and VCR? That can also cause this kind of interference, if both have power at the same time. There are video switches you can get to work around that. Here's one such switch (first I found for a decent price with a google search): http://www.pickeasy.com/20070827-video-selector-switch-video-game-p-555.html Hope that helps.
