Yes, It has focus control at side of fly-back transformer. Rotate focus control in both sides to get maximum sharp focus.

There are two possibility for this fault. The first one is, with its CRT base connector sockets. If this socket is bad, an out of focus picture will be displayed at first switch ON, which will gradually gain focus after some time, say, 15 to 30 minutes. If the humidity of atmosphere is high, it might take more than this specified time above, and might take up to an hour or so. Replace the CRT base sockets, and check first. The vertical rolling might be due to insufficient supply voltage from the power regulator board, and should be checked after you have rectified this out of focus problem.
If you're sound in electronics, and wish to get more details, check this link. Selecting the view option, either to Mosaic / Flip card, can be selected by the drop-down list, by the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

No Picture and Lttle red light next to power buttons blinks for about 30 seconds

First thing to do is reset ( see link below) and see if it resets otherwise if problem continues it will need some work

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. There are some common breakdowns in the High Voltage circuits in this set. One is the flyback transformer. Another is a small high voltage capacitor in the sweep corrction circuit. There is a cap that goes open in a high voltage circuit (C6532) which needs to be replaced.

Trying to pull out the convergence board so that I can replace the chips. How does the two red wires in the corner of the board come off? I'm trying not to break it.

Hi Kelso73,
These red wires can be remove by opening the front speaker grill. One of the wires is connected to the focus control and the other one is connected to the high voltage module.
Let me know if you need further assistance.

Picture will not remain in focus.magic focus feature fixs temporaily then condition returns

There is usually 3 flyback (hi voltage transformer) that gives the high voltage to the tube over the red wire.
On the flyback you got two adjustment. Focus and ''brightness'' ajustment. Sometimes, you can ajust from the back and they leave opening for the screwdriver entrance, otherwise, you remove the chipboard panel and adjust those screw. It usually write wich ajustment is focus directly on the flyback. As you can see its a bit of a technical ajustment, plus you have to do it when the tv is running and with the voltage on. Needless to say that its pretty easy to do a short in the electronics circuits. I hope you have someone handy with basics electrical skills. Also this might mean your tv have some parts getting in problems actually, but still it would be the first thing that i'd try in this situation... Let us know...

Have model F25190SE, old 1992 tv, Chassis CTC177AC. No signal coming in from rf connector, television all snowy. Can use the rca connections, still has very fine lines in picture. I've replaced the rf...

cristal and IC to be replaced and solderings on all grounds in the tuner unit. maybe costly for a tv of that age, for the fine lines there are 2 ajustements on the back of the tv set, one is focus and the other one is sceen, that ajustement is too high , just turn the ajustement counterclockwise. the tv will become darker

Low resolution

hi, there you need to open the cover of your monitor and check for three ajustments you will see them they are like screw but you have to be carefuly as the monitor is like a TV set it produce high voltage.
one of those screw is for contrast which is the one you need to focus on, if its not there there is a black like plug cable which is attached from the tube and the circuit board that one has got two screws one of those is for contrast try both if not sure (Caution!! that's the one that produces HIGH VOLTAGE) ask some one who know's about electrical appliances if not sure what to do.
