Vintage TV needs onsite service in Boston area

[zeno]

I was from the area (Acton). Everyone I knew is either dead or moved
to N.H. & retired. I know of nobody left but there may be one.

You could post pix of the problem & we can see if its something you
can try in house. You can also pull the chassis to fix it. If the CRT is chassis mounted you get the weight well under 100 lbs. If the CRT is separate
you can get a small test CRT to use

Good luck
