Looking for service info on a japanese set

[AlanInSitges]

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.

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.
