Flyback Transformer CTC177AD2 Chassis
 

Anyone have an extra flyback transformer for this Chassis? The one in my set turned out to be okay. However, I was told these can fail with age.

Thanks.

I worked on these by the hundreds. So many a shop I contracted for hired my son to to piece work on the connection / Eprom sets. Those sets
probably paid 20% of his collage.
Bottom line is I can not remember ever changing a FBT transformer
in one. That includes CTC175, 176, 177, 186 & 187.
Save your $$ or put it toward test eq. etc.

If it were not for those connections we would not have seen very many of these
sets. Quite good IMHO.

Not in the 27" they don't. I changed maybe one or two. They did fail in the 31-36" sizes. I changed a fair number of those.

No problem, I'm glad it got you back in business!

Hey Rustin, I hope you don't mind me changing topic on your thread again, but I got curious about my Magnavox set, so took the back off to see what it has in it.

Pretty much nothing except 20+ years of dust! I didn't find an option label, but Randy signed off on it, hahaha. It was interesting to see the HV anode cup says Chicago on it. I wonder if that cup was actually made in Chicago.

Not all of them did, but there should be some kind of label inside that TV.

No labels other than what's on the CRT & outside of the back cover. I got it new from w*lmart. Probably a cost cutting measure, so this doesn't surprise me. The equivalent model sold elsewhere probably had the labels.

RCA CTC177 AD2 Chassis Eeeprom
 

The Substitute eeprom in the set got the TV up and working again. However, since this isn't the exact eeprom that was in the chassis before we discovered there is no setting in the menu to adjust the color on the Set. The Color is what it is from the new installed eeprom. The color isn't too bad, but I would prefer a little more deeper color on the screen. I suppose there is no other adjustment to the color setting then? The Set ended up testing on the weak side in the picture tube. The picture isn't real bright, but good enough to use still.

Every version of that chassis had a color control. The only time I've seen options missing is when the eeprom is corrupt. The only thing I can think of is it being an institutional model, but even that seems far-fetched.

Was that new in the bag?

John

I got them for a plain old consumer 25" BPC RCA set, new in the bag from Dalbani. I don't know why, but I never threw the catalog out. I thought someone might get a kick out of seeing this, I couldn't find the year anywhere on it, but I think it's from the early 2000's.

RCA CTC177AD2 Chassis Acting up again
 

I had the 1996 RCA Set with CTC177AD2 repaired with it having the soldering connections redone, bad capacitors replaced and the Eeprom replaced. It worked fine for awhile. However, it is back to acting up with a snowy and rolling screen with flashing colors on the screen only on the Coax Cable out mode. If you run your video source on the Video Inputs it does not act up. Also, it was determined it has a weak CRT as the Blue Smear on the edges could not be corrected either. Any ideas on what is going on with it again before it is trashed?

Thanks.
