Hey I just got an old magnovox,ive recently heard they suck as a brand,anyhow when you turn it on the screen is black whith green lines horizontal and then cuts off

within 2 seconds.

Anybody know how I can fix it aside from whining to magnovox they dont care i didnt even get it from them.

[Strife26]

How old, what model, is everything hooked up right?

[DJ]

Tried percussive maintenance?

Tried percussive maintenance?

Seconded. Fixes anger issues, vents off stress symptoms, staves off depressions, keeps you healthy and occassionally revives old equipment.

[Heron TSG]

If it's a CRT, do not try percussive maintenance too far back from the screen. You could blow the vacuum tube, which would ruin the TV forever.

[Stargrasper]

Percussive maintenance typically doesn't work on electronic devices.  If it does work, it usually means a connection somewhere is loose and you just jostled it; that is, you have bigger problems.

Percussive maintenance comes from the days of mechanical stuff, where hitting the thing occasionally knocked out something blocking a gear or pipe or would break corrosion on a moving part.  Things like that.  These days, enough is electronic that percussive maintenance is often a bad idea.

Serial number <T117637ZERO3>

Model number <CT27ZEROMW8>

Manufacture date <MARCH,2007,Not sure what these numbers mean,<TX76C>

Its a big box tv,I heard it might have somthing to do with the capacitor not being big enough also heard it might be those little cylinder things might be loose,but I dont

know not a tv repairman.

Percussive maintenance still works on my cell phone, so Stargrasper can be safely ignored.

[The Fool]

It's the electronics inside the TV. If I remember correctly it should be the capacitor. There was a similar sounding problem with dead pixels in the CCDs that telescopes use. Entire sections of rows wouldn't work if the capacitor didn't work. But a TV is not a CCD camera, so it may not be the same.

[zubb2]

Actualy yes its the capacitor I found 2 knobs on the capacitor turned em around and got the tv working I have to adjust the knobs EVERY time I turn it on.

So ill need to get a new capacitor or just glue a screwdriver into the adjustor screw thing and just fix it evrytime I turn it on.

Tryed leaving it on forever but it made a ringing sound that I could hear from bed a room away.

I now have three tvs in my room.

[The Fool]

The ringing sound is likely from an inefficiency in the circuit. I wouldn't recommend leaving it as is. Excess electricity has a way of damaging parts over time, sometimes in a matter of seconds.

Have you tried replacing the capacitors instead? They should be pretty cheap. Just be sure that they are the same.

Percussive maintenance fixs every thing;
door sicking, Percussive maintenance
car dont start, Percussive maintenance
heart attack, Percussive maintenance

if Percussive maintenance fails you just need to aim better or hit harder.
