RCA Proscan 20" (PS20110, manufactured 1991)
Wait, don't delete this email! :)
Chassis CTC168 which is same chassis as famillar CTC169
commonly in 27", 31", 32", 35" and 36" CRTs also proj models of
42",
52" and 61" models and very long lived, reliable with few
easily resolveable problems (good money makers).
Now, this is not your run of mill 20" TV. These RCA 20" models of
any models I do service of all kinds of RCA chassis except
there is at least 2 models I heard about with particular CTC168
chassis which is only for 20". I've not seen CTC168
in my whole 3 years of TV service, even I have done so many
TVs and projectors with CTC169 chassis and all different kinds of
newer and older ones with types of RCA chassis. Except this one!
The features is LOADED for a 20" TV imagine loaded Chevy
landyatcht of luxurious stuff in an Omni (Rabbit look-like). Two RF
inputs, One RF out, Two video inputs and one Video output, S-video,
stereo ampified outputs along with internal stereo for set of 4
speakers total driven by either 5W to 10W ampifiers (most of others
usually muddy .5W to passable 1W stereo, 4 more unampified audio
outputs. and I think one or two sets of audio inputs. This is a TV
basically a features of a larger cousins of CTC169 for direct-view
CRTs and 3 CRT projectors. What a mouthful for a old rare model 20"
TV.
The extreme rarity there is a reason; back then was high price for
20", appox $500 so this particular models. Compared to 1990/1991
19"/20" of any makes/models typically run for 200 for plain janes
sh*t to high 250 for decent models with few features, except Sony
that had some features with outragous 300-500 tag!). I talked to
Jack, our shop boss and did say had one CTC168 in for repair years
ago and that was only one.
For me, this tv is like a find of a day. :) Akin to finding a PDP 8
on the ground with trash beside a rowhouse street very near downtown.
:) Back to your "exciting" regular programming, thanks and I still
enjoy your "text programmings" chatter.
Back on topic: Won L40SX (PS/2 386SX 20 laptop) on ebay, fairly
complete: power brick (Yes, a BRICK), quick charger brick, external
keypad and few booklets. Replaced LCD lamp successfully, old one
failed to light by extreme age. Took a IBM 4MB SIMM modified with
correct sensing pins and chewed off a SIMM socket's nub to get 8MB
instead of 6MB installed. L40SX takes deep middle notch 72 pin
SIMMs. Except most decent parity SIMMs can be used with proper
modifcations except 8MB had to be single sided and is max L40SX can
take for max of 18MB. To do list: rebuild battery pack and replace
two internal batteries for cmos and standby power.
