Question about Proton MM2701VT 27" TV

Analog Quasar tv keeps turning off.

My old analog quasar tv keeps turning off. It does this in very sporadic increments and sometimes when it's on it wont turn off. The only thing that helps this is when I bang the side of the tv. What could be the problem?

The bang test is a good indication that there are poor solder connections inside the set. If you can solder and are comfortable working inside the set where potentially dangerous high voltages exist even when unplugged, you can fix this yourself. Look at the main board and resolder any joints that appear grainy or have rings. That should resolve the problem. If not, see if there are any changes in the symptoms and update this.

How can I replace the outlet for the cables on the back of my quasar SP 3234E TV?


A "freezing" picture sounds like something other than your television. Do you have a cable box or satellite box attached? They fail sometimes and need to be replaced. (You have an analog TV and "freezing" is a digital problem.)

My old analog quasar tv keeps turning off and minutes and sometimes hours later it turns back on. The only thing that helps is when I bang it on the side and only then does it come on in that instance....

Is our Quasar TV (SP2723) a digital or analog television?


That's an analog TV and would need a converter box for the new digital broadcasting.

HD tv changes


The changes that you mention will only effect you if you use either rabbit ears or a rooftop antenna. The over-air broadcast signals are being changed from analog to digital. If you have cable or satelite service, there will be no change.

Quasar TV


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).

Digital


From what I see under amazon.com, it does not have a digital tuner.

But the February 2009 turn off is a deadline for over the air only.
When cable companies turn off their analog signals is a different matter. Some may soon, some may wait until 2012.

The gov't coupon program is only good for converters that handle the over the air digital ATSC signals, not cable's unencrypted digital QAM signals.
