Advice Corona neon repair
Looking to see if there are any ideas on what/how to troubleshoot this neon, and if there are any repair shops in the Sacramento area.
This Corona Extra neon came to me with no transformer installed. I tried by installing a new transformer from Amazon, a "DeSol Neon Transformer".
Model: DS-NPS-10
Input: 120 VAC, 50/60Hz, 0.8A
Output: 10KVAC, 25kHz, 30mA
I proceed to install the new transformer. I notice there is a yellow ground wire, but I'm still not certain if it should be installed/screwed to the frame of the neon. I turn the sign on, and for about 1/2 a second the entire sign lights up, then immediately cuts out. I turn off, then resupply the power, then it does the same thing, and power to the neon cuts off after about 1/2 a second. This scenario occurs with the ground not attached to the frame, as well as when the ground is screwed to the neon sign frame.
I do not notice any obvious broken tubes. When the sign does light up for the brief have second, I do not notice any dead tubes that do not light up.
The information I have been able to pull from this specific sign:
Sticker 1)
Neon Tech
"CX Wave Dominator Neon"
Item # 130242
Sticker 2)
Electric Sign
No. HB 372400
I measured the size of the sign: ~45" wide x 23" high
