1981 Magnavox with a problem.

[Bill R]

I looked and didn't find it. It may still be packed with some other stuff in th office. There is a folder of manuals missing.

I stand corrected. Yes, a grounded screwdriver should be used to discharge the residual HV charge on a CRT; I've been in electronics (as a hobby) and in ham radio 40 years, and should know that.

This is a good warning for newcomers to tube TV repair, however, as folks who have only known solid-state and, particularly (since the mid-'80s) flat-screen TVs may not be aware of the dangers of the redsidual charge on the CRT bell on old analog NTSC TVs -- even after the set has been unused for some time. The aquadag coating on the CRT bell acts as a huge capacitor and can hold a charge for a very long time, so discharging the tube by using a grounded screwdriver slid under the second anode cap until it contacts the terminal which connects to the 2nd anode well on the side of the tube is a must, before any work is begun on the chassis. (I would discharge the CRT even before changing tubes, as some older TVs had some tubes located near or directly under the CRT bell; I've owned a few -- my Philco Microgrid 390 23" console, now long gone, of course, comes to mind.)

Again, the voltage coming from the flyback in all CRT televisions is extremely high (20kV+ in color sets) and can cause serious injury or even death, so be careful. The voltage on LCD or plasma panels in today's flat TVs is nowhere near that high (several hundred volts at most), but, nevertheless, caution should be used around them as the potential for serious injury still exists.

Been away for a while, let me know if you find it.

Anyone here ever work for Magnavox?

[holmesuser01]

I said before that I was finished with this topic. I cant help myself. It's like driving by an auto accident. I dont want to look, but I cant help it.

First, how old are you, Firebird?

Second, you've been given the SAMS PHOTOFACT number for your TV chassis. GET IT.

Third, BUY THE SCHEMATIC. You live in a rural area? So do I, and I dont have this problem. Didn't you get and replace a load of capacitors from somewhere? Those arent made in rural NC, either.

Fourth, Go back to posting #60, and comprehend it.

Fifth, I'm not being mean. You won't follow the suggestions that you have been given. Nobody here can fix your set for you if you just throw parts at it.

This said, I hope that you have a very Merry Christmas, and hope that Santa brings you a T815 chassis.

The ones that are still around, probably ended up in a rubber room.
I never kept it a secret, that I was never thrilled with Magnavox TV's.
Too many PITA call-backs.

There were several Maggie models that gave me fits. Several of the tube models come to mind, and the first all solid state console with the board connectors that would literally BURN.

I got alot of repair business out of Magnavox sets after the factory warranty ended. Same with RCA, and a very few Zenith sets.

I needed the Magnavox name so I could buy parts from them, as they didn't like doing business with just anybody.

I'd consider a rubber room if the time ever comes. At least if I hit the floor, I wouldn't be hurt, much.

I can not find a repair manual. Does anyone know of a part that may cause these problems. Can a bad flyback prevent color or sound?

I thought the non-stop posts about that stupid Samsung annoyed me until I saw the threads on this set.
NOOOOOOOOOOOO DUDE. It is NOT YOUR FLYBACK (for like the millionth time) DUH!

I do believe the 5 hour energy I took has made me cranky tho. (haha)

[Firebird]

Very nice......... I wanna wish ya luck getting her going

I love a good Magnavox. Specially the old classic 25 inch consoles.

[jstout66]

I like that scene in the movie "Carrie" where the mother tells her: "They're all gonna laugh at you!" It's especially good when watching it on a Magnavox of that vintage that actually works........
