The RCA color TV chassis for your Home Theater is fairly common. They made lots of them and a lot of them still exist. The TV guys hold them in high regard as one of the better color TV chassis ever built. A Stereo Theater/Home Theater device is amazing in concept and execution. There has never been...

In the event someone is reading this and it will help them, I'll fill in some of the blanks. First off, very few Magnavox TV sets of any description have survived. The only ones that still remain in any quantity are the ones in the various Stereo Theater models. It is very rare to see a stand-alone ...

I didn't have to pull the chassis. I found the plug on the CRT shorted cathode to grid. I pulled the plug apart and overhauled it so the terminals were better insulated. I need to make some adjustments to make the picture as good as I can. Centering, maybe some horizontal width. The horizontal lock ...

Magnalux is Magnavox's automatic contrast and brightness control system. I believe it was available in the 1961 models, but don't quote me on that. Magnavox totally changed their TV chassis for the 1962 model year. We will, then, restrict this discussion to the 1962 models, assuming there are at lea...

We are fortunate to have an appliance repair company that is reasonably priced and doesn't upsell. They are an authorized Speed Queen repair facility. They replaced the ice maker in our old Whirlpool refrigerator for $300, which I thought was very reasonable.

I hope somebody rescues it to a good home.

I have to pull the chassis to dig much deeper. I need to figure out how to run the chassis on the bench with no CRT. I'm not getting much help from the "TV guys". I appreciate your input, Chris. Every component I have checked is okay so far,

The picture tube tests good! No shorts, good cutoff, emission barely into the "Good" scale, but we already know it will produce a beautiful picture. I don't see any components between the brightness control and the CRT. Nether the Magnalux circuit nor the brightness control has any effect ...

I have good news and bad news. Good news is that I have learned more than I knew about the Magnalux feature on this TV set. There is an LDR, light dependent resistor, in series with the brightness control. This LDR uses boost voltage. A series of resistors and the brightness control complete the cir...

The Home Depot down the street does not carry plumbing in any colors other than white or chrome. They do not stock black plumbing supplies. It has to be ordered online. They carry 200 8' ladders, and truck loads of blowers and rakes, but if you want a plumbing part that isn't chrome, you are SOL. Ho...

That theory went bust as well. Now I don't know what to do. What makes the brightness control to not work at all? When I turn the brightness down, it pulls the edges of the raster in. B+ is good. I'm open to suggestions....

I have too high of voltage on the elements of the 6EB8 video output tube. I have 245 volts on the plate, spec is 190. I have 125 volts on the screen, spec is 50 VDC. These elements get their B+ from a 245 VDC source, measurable at #20, which is pin 7 of the 6GH8A AGC keyer tube next door. My next st...

Well, phooey...... :roll: It's broke again. I started it up and all you-know-what broke loose. The video came on, then the picture sort of twitched, then I lost video. Still have raster and audio. Brightness control doesn't do anything, on full bright. Contrast control doesn't appear to do anything....

Our kitchen has granite countertops with a black sink and black plumbing hardware. The kitchen remodeling company who did the cabinets and installed the sink used the ultra-cheap hardware, the kind made in a third-world country with questionable to non-existant quality control. The paint started chi...

I was tinkering with the Stereo Theater this morning and ran across a DVD of the Lone Ranger. At the end of the first episode where Tonto finds the Lone Ranger and saves his life, I saw the date. MCMLIX. MCML would be 1950. IX would be nine, so MCMLIX would be 1959. I thought the Lone Ranger was lot...

It is. That is my test DVD. I fired the ST TV set up this morning. It came right up. I need to warm up the Analyzer and make a few adjustments, vertical height, horizontal width, maybe a touch on the focus. Watching an Andy Griffith DVD revealed that not all those old remastered DVD's are good quali...

I started this discussion on the "big forum", knowing there were more "TV guys" on there. They talk way above my head, get into stuff I'll never understand. They mean well, they had just as well been speaking Russian for all I understood what they said. I have to work on TV the s...

I'm sorry I'm talking to myself here. I wanted to share this little victory with you guys. Days like this are why we mess with this old stuff. We get over our skis occasionally, taking on more than we have the ready knowledge to handle. We make mistakes, we chase our tail. We fumble and we guess, bu...

I got it going! What I did to fix it may be best discussed another time. I'm beat.....

I think my next step is to dig into that tuner. That may be a part of the continuing issues I am having with this TV chassis. If it takes me a long time to get it done, it won't matter. I want this thing fixed. Any advice or direction would be much appreciated. Other than sending this thing to Shang...
