Wow! This is an old message!
If you haven't tossed your set out yet, the problem you have (or had) was a failing vertical deflection circuit. It is (or was) not a terribly expensive repair and if you have replaced it with a plasma or LCD flat panel set, I hope you didn't dump your Quasar since most of the flat panel sets don't last past year 2. Any of these sets have serious problems and I would spring for an extended warranty any any of them; they are TERRIBLE. If you have parked your Quasar in the garage, look for a surviving TV repair and have it fixed.  Some of the parts used in that set will be increasingly hard to find so don't put it off too long. Also, if you do repair it, get a converter box for it too; it will not receive digital TV signals without it and they are coming in Feb. '09

Just spend a few minutes at this site and do some searching on plasmas (worst) and LCD (still plenty bad).

27'' TV will not turn off demo mode


My ancient TV/VCR Quasar combo had the same problem...and I don't have the original remote control. But holding down the "play" button for five seconds did the trick. Perhaps your TV is similar. I also read that holding down the "menu" button works as well. Hope this helps.

20 year old Quasar colour TV (no remote)


That is because the switches of the front panel buttons are stuck or defective.

Try first unplugging power for ten minutes, this probably wont work.

To fix this the TV must be taken apart from an expert, and front panel replaced.

You can enquiry here for parts.

What you can do at home, is getting a replacement remote and using TV with a remote, or buying a freeview box, and watching and changing channels through the box.

You can get a replacement remote here: Replacement Remote Control orReplacement Remotes

My suggestion, if it is supported in your area, get a set top box with 30 channels : Freeview - digital TV from Argos.

After a few minutes picture shrinks to single line on screen and then powers off


Since the set works initially, there are likely poor solder connections at the vertical IC. If this is not addressed soon, the IC will fail and need to be replaced. The vertical IC is a small flat IC with about 11 pins or so that may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace teh IC. Feel free to post the marking here so I can verify you have the correct one.

TV turns off by itself


You are having a dry joint problem especially in the power supply. Resolder the joints in the power supply and else where. whenever your tv heats up the solder expand and break contacts. when your tv cools down the solder joints makes contact. If u dont understand, please seek professional help.

Shrinking picture


All symptoms indicate a problem in the vertical circuit,the first thing to look for will be loose conection on the vertical output IC,sometimes this IC goes bad completly and it needs to be replaced.If you are familiar with soldering electronics you can take care of it but if you are not too familiar you can play it safe and take it to a servicer ,it will be a lot less expensive than if they come to your house.Let Us know how it goes or if you need more information.
