You may have a cold solder joint around the Vertical circuit. Resolder the pins of the LA7833 IC and the components around the IC. Check the C308 220uf/35V & C320 100uf/50V. Nous Sabre. www.aaatvservice.com
The vertical circuit is malfunctioning. This can be as simple as poor solder connections at the vertical IC or a defective IC. If you can solder, you can fix this yourself. Please use caution as there are potentially dangerous high voltages present inside the set even when unplugged.
Locate the vertical IC, which is a small flat IC attached to a heatsink. It should have 9-11 pins and be karmed LA7833 or something similar. Resolder the pins first. If that does not resolve the problem, replace the IC (about $15-$20). It is possible that some of the capacitors in the circuit are also defective. If that is the case, the above actions will at least change the symptoms. Update this with any change other than complete resolution of the problem, and additional instructions will be supplied.
The easiest way I have found to set the screen controls is to tune into an old black and white show, turn the green up until you see retrace then slowly turn it down until it just dissapears then adjust the blue and red for a true black and white picture.
The LA7833 is a vertical IC and available several places here in the states. If you can go online try acme enterprises in Florida for the best prices. http://www.acme-sales.net/index.shtml
At ACME they're 1.79 american and they do ship to Canada and Mexico...
Hope this helps!
In the late 70's I was OJT for America West TV, the ink still wet on my CET diploma. I can remember my instructor Bod Fagren saying, "if you're not certain you can do it don't attempt to guess, ask questions..."
It sound like what youre describing is a loss of vertical deflection. This is usually caused by the vertical IC having shorted out. In the 61H60 that IC is Q301 an LA7833s Toshiba p/n#23319787 and costs about $20 bucks. But other components feeding that IC, resistors and caps should be tested to determine if the IC failed due to heat or was stressed because of higher than normal voltages.
In all a shop usually carries that part on-hand or has access to it. And the repair can usually be completed in a couple of hours. In short, I'd have it done by a reputable shop.
Taking the TV to them will help keep the costs down too.
If you're not too sure where to find a good repair shop try calling NESDA (National Electronic Service Dealer's Assn.) and they can usually give you a couple of referrals to one of their member's shops in your area.
