[Salvaged] 19" 1980 Panasonic Colorpilot PC-2000
Salvaged this really nice Panasonic Colorpilot Color TV on the weekend. It was manufactured September 1980. The Model is PC-2000 and the Chassis is NMX-L21. I don't see these old tv's too often around here, so i decided to grab it. Some jackass cut the power cord they had cut it right at the tip of the plastic moulding the old cord ran through, so I ended up having to make a new cord and run it through the square opening at the rear. After that, it powered up without a problem I really like the lighted dials as well. There's a couple of things I'm trying to work out. For instance I can't seem to adjust the black level, the brightness even when turned down seems to produce a over gray color and makes the image/video seem washed out. The other thing is the pull knob is very stiff to pull out and push in?

The most common thing for video problems on
this and almost all other brands is a cap in the 200V supply. I dont have a manual so hears how to find it. On CRT socket there are 3 identical transistors. From the collectors are typically 18K 1W resistors. Where the join is the 200V. Follow the wire down to the area of the flyback. the cap usually 4.7mfd use a 450V. Sometimes the cap is on the CRT socket board. There may be a small coil in series with the line. Some sets use a different scheme. Symptoms include dark on left, too brite on right. Retrace lines. smearing. Too brite. Some sets will over current shut down. May be intermitant. good luck 73 Zeno |

to add to the comprehensive service hints that Zeno gave, make sure you check the solder connections on the horizontal driver transformer. The connections will fail, giving you intermittent shutdowns. DAMHIK.....

Nice catch! I haven't seen many 19" Panasonics from that era. |

There are some people that are paranoid over trash pickers getting a busted set, hurting themselves (god knows how) with it, and suing, cut off the cords before throwing sets out....Those people are perhaps more ignorant than the scrappers IMHO.

Love these early 80s sets.. A TV on the side of the road around here won't even last minutes.. It's torn apart pic tube neck broke toke gone and power cord cut.. I can't believe before I caught on to this, I found a working early 80s quasar set that was very unique.. It was slightly wet or damp when I tried it.. I got a pic but no sound.. Decided to leave it by my car near the road for the sun to bake it, and when I came back out hours later, it was completely gone.. That was the time I didn't have a big storage unit, and had no where to put it, so I left it by the road while figuring out what to do with it..

The recycling programs now in place in many cities have reduced the number of old TVs put out for the trash, and some municipal waste disposal services will not even touch an old set, due to the safety hazard posed by the CRT. I live in a very small town in northeastern Ohio (been here 15 years), and have seen very, very few CRT TVs out on the curbs; the safety issue may very well be the reason. I don't know for certain, but there may be an ordinance here against putting used appliances and/or electronics out with normal household trash on our scheduled pickup day. If there isn't, IMHO there darn well should be.

Any child that can get into the back of a TV is big enough to survive the HV charge on the CRT unharmed....Unless the kid has the weak heart of a 98 year old. As for broken glass I used to collect it when I was a kid. My neighborhood used to be the town dump before WWII, and if you dug you'd find glass, and other artifacts...So I collected them. And I never got cut from it! I used to throw rocks at SS era CRTs till they would break and they never imploded. By the mid 60's implosion protection was good enough that it was nearly impossible for one to occur. Besides the rule is until the garbage men take it, it belongs to the disposer, and if you steal it and hurt yourself then it is your own damn fault.

I was adjusting the focus on a 90's RCA with the remote HV test points and stuck the screwdriver in the test point instead of the focus control. Since I wasn't paying attention I also wasn't holding the screwdriver by the handle. That woke me up!
