Help with Removing Stuck CRT Socket (Sony KD-34XBR970)
 

Hello,

I have a Sony KD-34XBR970 and am trying to remove the board from the end of the CRT (the "CH board") for repairs, but it is pretty stuck. I'm trying to be very gentle about pulling it straight and slightly wiggling it, but it won't budge.

Is there some general advice on how to remove a stuck CRT socket, or any particular tips for this set?

Thank you!

I've had a couple of sets with that chassis, but never saw the socket stick.
Be careful not to crack the PCB. Perhaps something like lighter fluid, or kroil drizzled onto the gap between docket and base might help... If there's enough gap to get a very small screen driver between the base plastic and socket some light prying might help.

I had something like that happen before; it was not a Sony, but a monitor with the same type of PCB, it would not come off no matter what, came to the conclusion that some fool must have glued it on, so I had no choice but to unsolder the socket to get the dumb thing off.
Not saying that's this is what is going on with yours, but dumb things like this DO happen! :yes:

This is probably a dumb question, but I'm assuming you've already checked and double checked to make sure there are no physical clips or other devices holding the neckboard onto the neck? For example, my RCA has a plastic bracket on the neck with two clips that clip into the neckboard, and if you try to take it off without releasing those clips it's not going anywhere.

I have found that if the factory used RTV on the CRT socket it can sometimes be VERY hard to remove. Wiggle,coaxe, and pray nothing breaks.

UPDATE: I successfully removed the board, with use of electronic contact cleaner. I sprayed at the front and back of the socket with DeoxIT D5, and let it soak for a short time and then gently wiggled the socket side-to-side and top to bottom.

I avoided using and penetrating oils because I was leery of having petroleum residue on electrical contacts.
