Starting work on the Sylvania 7140M

I had a lot of bad micamold capacitors in my '49 set also. Even the ones that were really mica. The other brands were fine.

There's not a lot of difference between your 7140M and my 1-108. The video is DC coupled so the brightness should be quite stable. I would have thought that if anything, they'd put the brightness in the rear and the contrast in front.

I've attached the AGC adjustment for the 7130. I think it should work for your set too, but use pin 5 where it says pin 6.

I have a Sparton set at my folk's house with the contrast in back too, I agree it's not the best idea. It's a 21" set, and pretty cheap too. Maybe they were just trying to simplify the controls for users?

I got the Mica Caps from Mouser and installed them, I also went ahead and rewired the width coil circuit to match the schematic.

The set now comes on with the Horizontal locked and stable, no smearing, there's a very slight amount of ringing on the left side, a new damper helped and it's so slight it's not noticeable unless you really look for it on blank scenes.

I forgot to fix that vertical integrator thingy but the set works just fine without it so that can wait until the next time.

I cleaned the safety glass and the genuine simulated woodgrain screen surround and put the chassis back in.

I made and posted a quick video here:

I played that video through twice without a hiccup.

I just need to polish the brass covers that go on the small knobs for the Volume control and Channel Selector and glue them back on.

When I try to view the video it opens Adobe Flash Player 9 but does nothing.

Congrats It looks pretty darn good to me!


P.S. It played in Windows Media Player fine for me. Maybe you need a newer version of flash ?

[David Roper]

It didn't open in any window for me, it just downloaded. When I opened the download it played fine in WMP.

I think you need Flash player 10.

I converted it to Flash by uploading it to YouTube then downloading it again, (then I deleted it from YouTube) that was quicker and easier than converting it locally and it reduced it from 50 meg to 5.

It plays in Real Player, Media Player and Quick Time for me, you might try downloading it and trying different players till you find one that works.

I'm giving up on this. I tried Winamp, Media Player, Quicktime, none of them would play it. I tried upgrading to Flash Player 10, it still opened Flash Player 9 when I open the FLV video. I tried all of Adobe's solutions using their uninstall tool, restarting and re-installing Flash Player. Adobe's link to check the version installed shows the correct version and it plays their Flash correctly. But when I try to open the FLV video it still shows the version 9 player and the media players can't find the codecs.

Adobe tricks you into installing McAfee by putting a small checkbox far away from the download link and defaulting to opt in for install. That was sneaky.

I'm dissappointed with the newer versions of most of their free software. I'm reluctant to upgrade to a newer version of Acrobat Standard because of the way their latest reader performs. I'm reluctant to pay for support of their free programs.

I can't even find where Flash Player 9 resides. It doesn't show up in the plugins, only version 10, nor does it show up in add/remove programs.
