CTC169 Woes...
First off, I'm new to this group, thanks for taking the time to read this.
Now, this 35" RCA is driving me nuts and I'm questionning my ability here. The problem this set has is as follows. With any input, (rf, composite), the video is distorted, I mean, the image has what look like 60 cycle hum bars, not moving, just there, couple of inches from top n bottom. It'll lose vertical sync sometimes if channel is changed. Chroma either disappears or is severely shifted. Skin tones go from normal to almost flourescent green. Horizontal width is affected slightly on the right, (1/4 - 1/2" black, slight pincushion, not enough to suspect pin circuit though, probably due to this irritating problem.) The jungle has been swapped as a result of the 'shotgun' approach suggested to me, I have the schematic, it's not helping. Am I missing something very basic? Please help. Cheers, Steve |
