Hi All,
I received a 'South Park' pin today, and first thing i noticed was how dark the playfield was, then realised absoluterly NO G.I. (General Illumination) Lamps were working.
Here's what i checked (as normal):
- Checked GI fuses, nup, still ok.
- Checked 6.3v AC coming into G.I fuses - Yep.
- Checked solder joints around GI AC-in and fuses and output connector- all ok.
- Checked 6.3v AC was leaving driver board into GI loom (when GI Relay is energised) - yep....
- Checked GI looming under playfield, all in tact.
Damn.....I decided to pull a lamp out of socket and confim volts was actually on the lamp sockets - yep, all ok too....
Hmmmm, Checked a lamp - Blown!
Replaced that 1 lamp and it came on, but all others still out.....
Checked next lamp - blown, next lamp blown, next lamp blown.....
Removed 25 lamps - all blown ! WTF
!
Replaced 25 lamps, all working fine'n'dandy now....
WTF, how did they all blow? unless they died slowly over the years and previous user didnt know how to change lamps ??? although i would never expect EVERY lamp to have died.
At first i thought maybe previous owner put 1.5v torch lamps in, and they all blew at 6.3v, but the lamps are clearly marked '44'....standard issue....
Moral of this story? test your lamps FIRST before blowing 2 hours inside the box hehehehehe.
Hope this helps someone in future.
MM.
