JVC av36850.... Same tube as d-series? RGB modable?

Post by deezdrama »

So ill be about 3 hours north of me to pick up a sweet 20" panasonic broadcast monitor and some pvm's tomorrow. While im there i figured id look on marketplace in that area. Ive always wanted a d-series but never found any around me.
I see this 36" jvc for free.
Black,curved, no component... Im wondering if it would be worth grabbing?
Anyone know if its the same tube as the d series or its tvl count?
RGB moddable?

I can find absolutely nothing on the model number on the web.

It's worth is subjective, but if you have the space and muscle to haul a 150lb set why not?

Service manual is accessible from a Google search of "AV-36850"

I'm not sure on tube model compared to the D-Series, but JVC used the same tubes in a lot of sets. My old 27" D-Series was a Thomson made tube that was in all sorts of brands and models.

This set looks to be RGB moddable by the standard OSD mux method.

All I could find is the models user manual

Thanks I can compare the 2 now

JVCs up until around 2001 were RGB moddable. They all have excellent picture quality (same tubes that they used for the D series). However, the jungle chips they used don't allow you to set brightness and contrast for RGB from the user menu which is kind of annoying if you use the TV with different levels of room lighting.

For that reason, I personally prefer the JVCs with component input, even though a lot of them can't be modded. Their component video quality is crisp and perfect so there's no real need for a mod if you have a converter.

It would be a fun project if you have the space, considering it's a free TV.

Thanks for the info.
Im leaving this morning and driving 3 hours north to meet the guy I get my pvms and pro monitors from, the 36" jvc is another 45min north of his location so I guess Ill see how I feel after im done picking up this broadcast monitor,pvm's and how much daylight I have left.

So how is rgb picture and brightness adjusted? By resistors on the mod/lines or by service menu?

You can use the screen pot & the RGB cutoffs to get RGB to a good level, after which you lower sub-brightness to bring composite back down to match.

Or you can use higher value terminating resistors on the input.
