I had looked all around and no where I can find the chassis number. The only label inside the cabinet have the serial number and " F19421" as the model number, as far as I know, RCA chassis are CTC, there is none. There is no other label.
I plug it in yestarday and the set worked ok, then it when into a horz line. So now I got a clue, Vertical Defelction Circuit, or the Video Jungle Chip.
After I shut it off, now is dead again and will not start.
But like I said, since it went into a bright horizontal line, that clears the power supply & Horz Circuit.
I will check the Vert output next, I had to replace the modem on my pc and modem + sound card of my girlfriend's pc yestarday because the damm storm ( lighting ), that's why I dint check here sooner. Thanks to all here for responding to me.
