Re: Tube radio tuning thread slipping
The dial cord may will likely need replacement, good luck finding anyone who can do it. There are some chemicals ("non-slip" from GC) that might be applied to the cord at the dial or at the tuning capacitor, but I would recommend that this be done by a tech.

What kind of make, model as well as year is this tv??
If you replaced the board make sure you have replaced it with a working compatible board the board your friend replaced may have burned out or shorted out due to some other undiagnosed problem and if board is replaced again it may do the same and your tv won't be working for very long
I really need to know what kind of tv as I asked like make model and if it is a newer smart tv or if it is ancient or just older or what and because I don't know make model year etc... I am speculating across a whole variety of different types of tv's the answer I wrote below is based on very old antique tv s and I had this problem once up on a time
If it is a old tv with the avf/khu knobs i know on my old tv i had a tuning knob and when i wanted to watch tv i would have to define and adjust the picture by turning this knob i call the tuning knob kinda like on a radio also if i switched from tv watching to play my nintendo etc... i would again have to tune the picture to decine the gaming picture and so on
The tuning knob on the exterior of the tv is also connected by parts to the interior of the tv which can also be adjusted if your knob breaks on the outside you can still adjust from the inside some older tvs only have this tuning knob on the interior parts so that the technician can set it before returning to customer again this is only applicable to the old style tvs mine being pre 1990 and i am unsure as to your make model so on
Also did you ever end up changing the board yourself or was it just your friend who told you he changed it before you received it?
Let me know about the make and model as well as year and we can go from there
Bobbin thread breaks
1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly
2. Lint has collected in the bobbin holder
3. The bobbin is damaged & doesn't turn smoothly
4. Lower thread tension is two tight
Assuming the antenna is mounted and grounded correctly,when you try to transmit/talk does your meter needle move to the right with your voice,if it doesn't make sure meter knob is set to receive/transmit or mod[modulate] does it move to right now,if not make sure the mic gain knob is turned up or if it is a power mic,is it turned up&have a fresh battery.The antenna light could mean high swr readings which you will have to adjust by tuning the antenna with the radio meter or external meter,you can search swr adjustment on your computer if unfamiliar..some antenna warning lights are factory set too sensitive but most times are telling you there is a problem.If all is set&tuned properly and you still can't get a local signal to respond, your radios transmit finals could be blown,which you'll need a qualified radio tech to determine..Good luck& 73's

The right hand shaft knob contains the coarse focus locking clutch adjustment mechanisim( big name-simple design). This solution applies if you have the model with the fine adjustment wheel mounted in the base and may or may not apply if your fine focus is in the left-hand knob.
Inside the right hand knob ( as viewed from the rear of the scope) is a threaded disk/nut which has two pins (Slightly and for reasons I don't understand: they are offset vertically, they have different pin diameters and different pin lengths) In theory, they lock into the bushing within the knob proper to keep tension on the clutches while keeping the knob from falling off.
The repair can proceed in two ways depending on if the disk/nut has totally been unscrewed from the focus shaft.
Gently pull the left knob and as you do turn it slowly to see if the pins reseat. If they do you'll feel a slight lurch outward of the knob. Hold gentle outward tension( so as the pins remain seated) as you turn the knob clockwise until the slippage in the clutches is so lessened that your knob is firm and the focus adjustment is operating to your liking.
IF that didn't work it is likely that the threaded disk/nut has come off the shaft and will need to be reset and screwed back down. The disk is easily cross threaded and you'll need tweasers or micro plyers or a hemostat and/or a flat headed finishing nail. Plus I recommend a small bottle of LOC-TITE(tm) semi-solid thread sealer--NOT the kind that freezes the threads
As you unscrew the knob counter clockwise pull on the knob to slid it off the shaft it should come off in your hand revealing about 6-8 washers on the shaft. These are the clutches so be careful not to loose them.
The knob should have a slight rattle and that is the disk nut. To get to the disk/nut put a small finishing nail head first into the shaft whole and push to release the plastic knob insert cover out being careful to not loose the disk/nut.
To clean the threads and insure an easier repair screw the disk onto the focus shaft to insure the threads are clean.
This next part works better with the scope lying on its left side.
This part is optional but not necessary to get the scope back in operation. Place a tiny amount of LOC-TITE thread sealer on the shaft threads. This will make the knob clutch adjustment more stiff but will also reduce the likelihood that the knob will be adjusted out too far again. The loosening occurs when the knob is turned before the operator realizes the pinion gear limit has been reached or by someone who dosen't understand correct opperation of the focusing assembly.. So long as the clutches are engaged the and there is no slack in tension the disk/nut shouldn't come off the shaft again.
Observe the pins in the disk/nut and match them up with the holes in the aluminium/brass knob bushing. You'll have to wiggle the disk around to get it reseated properly. Once you do, hold the disk firmly against the bushing to keep the pins seated as you put the knob back over the shaft, pushing it all the way down against the shaft.(The clutches are springy so don't worry about it locking in place just now).
You may prefer to hold the disk/nut and knob firmly with a finger and spin the left hand knob counter-closkwise for easier threading of the nut but remember this will also move the focus arm. Not a problem if you start with the focus in the range centered.
If using the right knob: Turn the knob clockwise feeling for the threaded shaft maiting back up with the threads. IF it cross-threads, back it off try again. Once the threads are engaged keep the outward tension on the knob so the pins don't slip out. When you/ve screwed it down far enough, the clutches will take up the slack and keep the knob from slipping away from the disk/nut. You'll know the clutches are engaged when the focus shaft turns.
If you are happy with the repair slip the knob cover back on and snap in place. It if falls out place a little of the thread sealer on the rim and try again.
