Question about Proton MM2701VT 27" TV

1 Answer

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. What could be the problem?

This 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.)

Mitsubishi CS31305 TV turns on then goes to snow and then back on


snow basically is a symptom of weak signal.

as you say it becomes ok after 5 minutes or so there no question of any components gone wrong except loose or print intermittent

please check.

1  input weak like cable or antenna or loose wire from the source..

2  in tv antennae socket loose.

3  near tuner any thing loose or track loose.

4  cable wire might be old.

hope this will help.
