View Full Version : Looking for service info on a japanese set
mbates14 12-19-2021, 07:55 PM I have a japanese (NEC) made Packard Bell set that I am trying to find service data on. I picked this up in june but i cant find anything on it.
Any help would be appreciated. I attached pics of the set. Model would be a C95266 WAL
AlanInSitges 12-20-2021, 10:19 AM Are you sure that is the right model number? It looks like a P-B model, but according to the internet it doesn't exist. Is there maybe a chassis number?
If you have access to a Sams collection look through all the P-B sets for a similar in the date range. Note that Sams has no TV's from NEC of that age that I can see.

No, I do not have access to any Sams. Therein lies the problem. All I know is it appears to be an NEC made set.

Welcome to my struggle. That is the correct model number, and I cannot find the actual NEC information on this set, nor its chassis number.
There is a short somewhere in this set, but the CRT is marginal as far as tests are concerned, and I cant find a replacement either so i need to determine if I am going to fix it or not. Without the service data though, I am flying blind.
I picked this one up plus a couple others from the boiling springs trip i took from a TV shop building that was being sold off to a new owner.
It looks, smells & tastes like a NEC. NEC printed the boards with
a big NEC marking & all I remember had NEC branded tubes.
At this point get an RCA, GE, or Sylvania tube manual. that will
at least give you the tubes use, specs & pin outs. Curtis Mathes
( C-M ) also used a lot of NECs so you can look there. All the
others I saw were from unknown brands. I NEVER seen a NEC branded set
with tubes, the NEC branded sets suddenly appeared in the mid 80's.
& sold very well at the high end stores.

BTW what is the problem with the set ??
ARC Tech-109 12-20-2021, 04:59 PM If I didn't know better I'd almost say it was either a Toshiba or Matsushita derivative from the early 70's as they were still doing tubes until the Quintrix days. I remember seeing this type of set in my youth as the LH HV cap got me.
Would have become an Xmas break challenge for me back then. I really liked them and had both an Ambassador 19" and Panasonic "swivel set" with the controls on the bottom and the top on a ball mount.
I can't see what the label on the left above the power connector reads, NEC used to go by Nippon in the early days, had a 3/4" VTR marked NEC with the label reading Nippon Electric Co Ltd.

i thought i mentioned in an earlier post. There is a short somewhere. im sure its capacitor related, etc. but i wish i had the service info or at least schematic. because its going to have the parts diagram and values, such as if i ran into a fried resistor, id be screwed trying to determine its value.
ARC Tech-109 12-20-2021, 07:36 PM Personally I'd carefully pull the chassis and do a good cleaning then triage the components replacing electrolytic and tubular paper caps while keeping a close eye for the burnt carbon resistors especially around the power handling tubes as they get baked well. I wouldn't worry about the pix emissions at this point, get the chassis stabilized first, it can be done without a manual and you have one of the best service tools in your hand... the camera on your phone.
Certainly wouldn't mind finding a set like that.

Yeah i will do all that, and yeah i figured that. I just was hoping there may have been some service data out there that someone has. thats all.
And also yeah these sets arnt exactly common, thats for sure. I picked this up with a few others at a place local to me that Shango066 and radiotvphononut got their start on years and years ago. They were doing a purge off in the summer before they had to turn the old building over to the new owners. The warehouse my still be there but im pretty sure those tabletops are long gone.
damen 12-20-2021, 09:27 PM It looks a little like this Panasonic in Sams set number 1127, folder number 1.
Electronic M 12-20-2021, 10:38 PM It looks a little like this Panasonic in Sams set number 1127, folder number 1.
I'm pretty sure I have seen a Sam's more similar to it than that.
Tomorrow night I'll flip through my color duplicates (back when I got rid of my duplicates I kept the color folders, FM MPX adapter folders, and any folders for sets I owned) and see if it's in there.
kf4rca 12-21-2021, 06:52 AM That's legacy technology. I'd check the sound output tube first. Then the Horizontal output and damper.
Yes, a good visual is important. Might be a paper clip, bobbie pin or even a penny laying on the circuit board.
At one time, NEC said they were going to pull out of the North American market saying it was too competitive.
Not many people know this, but NEC made transmitters also. Big ones like 100KW. TV61 in Chattanooga had one.

Woah that looks like it is it. do you have a digital copy of it somewhere?
Tube TV 12-21-2021, 02:04 PM The only reference to that model number I found was in a Feb 1971 Electronic World.

WAL at the end likely means walnut finish so I left it out and found that result.

Dang. I guess they are that rare...
I think I have a binder full of sales brochures that it is in. I need to go through that thing someday and scan it/archive it. Just for posterity.
I would go with the Panny set. Any differences should be minor.
The only thing not Panny is the lack of red "remove me" screws.
BTW dont get a copy from Sams. Poor quality & too much
$$ OLNY OEM paper Sams are good, in fact very high Q.

Be damned if I can find a bigger image though that give a model number and sams photofact numbers.
Its's off somone photofact ebay listings.

I just went with quick and easy and got it from the SAMS website. I don't have much alternative other than waiting for a paper copy to show up. I dont have any sams catalogs at all.
kf4rca 12-22-2021, 06:26 AM How do you know there's a short? You might also have a blown diode in the bridge rectifier. Have you brought it up on a variac yet? That's what I'd do on a set that hasn't seen power in an unknown amount of time. It might save your filter caps.

I just did the brute-force method dry checking piles of TVs at the time. and one of the resistors started getting toasty/going up in smoke. so i quickly unplugged it. I will be honest, I haven't been in the tube game in well over a decade, almost 2 decades and I don't have the tools anymore so I have to start re-acquiring everything. I did get testers and things, but a variac is on my list. Tube stuff was primarily something I did as a teenager way back then, life happened and eventually got out of it before interest slowly rekindled. I was still a teenager when I first joined this forum.
I have a pile more of sets i need to analyze before i get a parts order together.
ARC Tech-109 12-22-2021, 08:07 PM Got your work cut out now. Still its a set worthy of a good restoration given its condition and just how rare they are.
Unfortunately we didn't even have a BBS when I was a teenager, the Commodore64, Apple II and Atari 400/800 were the dominant computers.
