Hog 1000 backlight replacement (retrofit Cold Cathode with LED)

image

The backlight on my Hog 1000 died, this is not surprising considering its age and the fact that backlights do eventually die! Sadly the inverter and cold cathode tube for this console are no longer available so I decided to replace it with some LED strip!

I first removed the main PCB then the LCD, I de-soldered the inverter and took the cold cathode tube out of the casing.

I removed the foil that covered the tube and slid a strip of daylight LED tape into the aluminum holder (covering the terminals on the tape and the cable where it exits) with some PVC tape.

Finally I found a12vdc supply from the rear PCB and I put the console back together!

It works a treat and is very bright, you can’t control how bright it is from the console anymore and it doesn’t automatically switch off when the console is inactive but beggars cannot be choosers and it works brilliantly!

To get around the dimming issue I have ordered a 12v LED dimmer switch online and plan to fit it just under one of the wooden side panels. I did consider taking a feed from the other LCD backlights so that they dimmed and turned off together in the end I decided it was safer to leave them as they were and not fiddle too much!

Better than new!
