Question about Panasonic CT-32HXC14 32" TV
Hi, see below for more info, I am trying to find a parts source for this plastic socket guide. it is the piece that fits on the end of the CRT to protect the glass end and support the pins, it also aligns the neck board socket so it goes on correctly. also, is moisture likely to build up on the neck of the CRT? I live in the southwest US where its normally pretty dry, seems odd that moisture would collect inside the set. I still plan on getting the service manual for the set and verifying all the neck voltages etc. don't want to repair it and have it arc again because I overlooked something. Also, if you know the actual industry term for this part so I can search the web for a replacement that would help too. If you need photos ans measurements of the part let me know. Thanks

there is a random arcing between the pins of the crt neck connection on my CT-32HXC14J, worse on power up , gets less as it warms up. I have isolated it to under the plastic alignment cap that fits over the end of the CRT and its pins. After carefully cutting thru the sealant that holds the plastic cap to the CRT neck and cleaning off as much of the charred and blackened sealant as possible, the arcing has gone away. I need 2 things, 1 what should I check that might have caused it to start arcing, i.e. B+ too high, bias off, loose ground etc. and 2. whats the best way to clean off the glass around the pins to reduce the chance of re arcing? should I use some corona dope coating as well? Thanks
Comment by wastric, posted on Jan 08, 2008 I hope thats all that caused it. anyone know where I can buy a replacement CRT base socket , there was no arcing on the neck board socket half so its good to go. I really don't want to leave it without that socket piece. it makes sure the neck board goes on correctly, and helps support the weight so the crt pins are not carrying all the weight. Its been a long time since I worked in consumer electronics so any ideas about a parts supplier that can get me that plastic socket end/guide would be great. I can post a photo and take measurements of it. Is it a generic part or unique for every make of TV?
Still need a solution for this problem?

If anyone is looking for a solution to this problem my CRT tv was arcing as well. I disassembled the white socket that the crt plugs into which is on the neck board and found a TON of corrosion making it hard for electricity to pass through the connections. I cleaned them as best as i could and the set quit arcing. I figure the excess energy it couldn't pass through the contacts arced to the next pin over.

Don't know what happened to the last post I sent you its disappeared.
What I think you should do is definately replace the CRT white socket (tube base plug).
You can either take the CRT number from the label on the tube & put it in to google then search for Crt base plug.
Or see if there is A repair shop local to you who can order the tube base for you.
Are you definately sure the arcing is external to tube & not happening in the tube neck ?
Is the CRT made by LG / PHILIPS. These are notorius for for arcing over internally I must write at least 1 A week off for this problem.
If you can still run the set try tapping the neck of tube with screwdriver handle if pic flashes or goes predominately1 colour you are looking at the tube with internal short.
If this is the case there are ways of trying to get rid of the internal short let me know what you find ?

SOURCE: Arcing between pins on CRT
Your problem is due to moisture in the the Crt base socket you will need to replace the white plastic crt plug I have tried to clean & dry them out but it never fully corrects problem.
As far as the pins & glass crt neck goes clean them with Isopropyl alcohol this will thoroughly clean all the carbon off.
