Re: hi again!!!
The RCA jacks should be near the signal board. The vertical will be on the same board as the Flyback which Is a large transformer with the large red wires coming out of it. You shold be able to remove the screws in the chassis and slide the chassis out and tip it up so you can see the under side of the boards.

I repaired one these. The convergence board is bad. You will have to change the two STK Ics. These will have, I believe thirteen pins, mounted on large heat sinks.. And that is not the only problem. You will need to resolder this board as there are as many as 15 bad grounds. This board is very thin and you need to exercise care pulling it out,desolder, install and solder in the new ICs. Once again this board is very fragile. Another name for this board, is the signal board, look for all the RCA jacks and RF connections on it. Thanks for asking
The ticking sound is almost always caused by the Flyback and Hot transistor. It could be other items also located on the deflection board but flyback is most likliest. You can get a replacement flyback and Hot tarnsistor from www.tvrepairworld.com
If you can remove the back cover off the TV, do so. Be sure your TV is unplugged of course. You will see two large boards on the floor of the TV. If you can look between the two boards, you will find three or four jumper connections that connect these two boards. Remove jumper jack (location # 1516). Now plug your TV, power your TV up. The TV will come on. You may notice your convergence is off considerably. To correct this, there are two different ways to repair this. Contact www.TvRepairKitscom. This website is very helpful, and will lead you to a repair. The second idea is to contact Union Electronics at 1 800 648 6657. You will be purchasing or sending your board in for repair. You will tell them, you are need of a signal board module (has all the RCA jacks and RF connections). In both cases, you will need the model number and chassis number. Try this advice, I think we are on the right track. Thanks for asking and show all hands of support!
Remove the back panel from the tv where the input jacks are located. You will see a red power wire. Just above that and to the right approx. 7" or so you will notice a [_] shaped metal shield surrounding a cgreen/gold capacitor. You may need to remove the plastic cover that is located directly above it about 6-7" in length to gain easy access. Run your finger over the top of the capacitor. If it is beveled rather than smooth you have found a definite solution to your problem. The part number located on the board is CP150 16v 2200uF capacitor. It will look like a tall cylinder. Good luck!!
Your set uses the 195 series chasis. The only thing I can think of which would make the channels scroll by themselves is a contaminated PC board and pushbuttons behind the buttons on the front of the set. This is usually the case when spray cleaner or some other fluid is sprayed or spilled on the screen, and it drips down onto that board. To prove this, remove the back cover and on the top of the main chassis, where the top of the picture tubes are, is a small PC board with the remote reciever and a couple of jacks. The smaller jack is for the speakers and the larger jack is for the front panel PC board. Unplug the larger connector which goes up to the front PC board and then turn the set on with the remote. If the set works normally, the front PC board will have to be removed and cleaned or repaired (or just leave the jack unplugged and work the TV from the remote only). If you do not have any experience working inside projection sets then allow a qualified tech to handle it for you.
