2000 RCA Entertainment Series 27" console model G27647 problem
 
This set has been on the front porch of a house after owner passed for some time. Cosmetically has held up pretty well with the exception of the power cord being chewed in half. I cleaned it up and plugged it in today only to find a line running across the screen with only the bottom half displaying anything. I've been having problems with my camera this past week so the pics are terrible. Any idea what's causing only half the screen to show?

If only the white line was showing, I would say the vertical oscillator or output tube is defective, or the vertical output transformer was open. If only half of the picture shows on the screen, however, I don't know and would not know where to guess the trouble might be (I've been away from electronics for over 20 years, having had to give up my workshop in my former home in 1999 when I moved to an apartment late that year--long story and OT).

Your camera seems to be working if it is producing the images you are showing in your post, so I wouldn't be too concerned about it. The first thing I would do, however, would be to charge the battery(ies), if your camera uses one or more such cells.

BTW, I am amazed the TV is working at all after sitting on a front porch in goodness knows what kind of weather (!) for years, the only damage being a chewed-up power cord. Most electronic devices, let alone very old televisions, will not take that for any length of time, and would probably go up in smoke if plugged in and turned on without being dried out first (if the set has been exposed to water for any length of time, as this one seems to have been). Replacing the damaged power cord is a good first step, but there is almost certainly other damage under the chassis which must be corrected before the set can be considered repaired for good. This TV is not all that old, however, having been made in the year 2000, so whatever is or may be wrong with it may not be as bad as you may think.

It's totally dry. Doesn't seem to have ever been wet inside. Particle board and mdf don't last long in dampness. Everything solid otherwise. I remember running older 19 inch sets that had been in rain outside for many long months and I actually got lucky alot. That was probably 25, 30 years ago lol. I might try to connect a vcr or something and see if I can get a better shot

I have a 35v 220 uf. Will that pass? If not, I'll have to look and see if I have a 100

You can go 10% higher so it would work. you can go higher but not lower.

Awesome. Kinda figured but couldn't remember. I'll update once I get it in.

pac.attack76 06-09-2022 10:23 PM

Ok I kept looking and found a 35v 100 uf so I'll be putting it in a couple days or so.

pac.attack76 06-11-2022 06:51 PM

I'm finding 2 that are 35v 220uf but no 100uf. Maybe I'm looking in the wrong place. I'm not familiar with the ctc203ax I wish I had a diagram. Doesn't help that I need glasses for close up stuff lol

jbattles 06-11-2022 10:55 PM

its usually the 35 volt that goes bad.

So it's one of the 35 220?

jbattles 06-12-2022 03:41 PM

it was always the 35. i would replace anyone close vert output. you can pull caps off old junks boards. remember you can go higher but not lower. that's both volts and uf.

Ok so it must be the smallest one in the pic. It's a 35v 220uf

jbattles 06-12-2022 10:24 PM

yes that's the closest to the output. there's just three caps just replace them and go from there. like i said you grab them off old boards. when i had my shop i would buy allotment of electronics from goodwill in Atlanta. Now there might 60 TV's 20 VCR's and they would throw in microwaves. I don't work on microwaves, but i had to take them all, but for 50.00 cant complain. The first ten i would use for parts. The first set i sold made back my money and the rest was gravy. I just my time it, so keep that in mind.
