The black and white displays were built by PHILIPS in Canada. The plant there has been shut down, when I last enquired with Philips re: purchasing spare parts, I was informed that they did not want to support anymore new customers for this product line. Philips makes the new HP b/w monitors too, but it looks as if everything is manufactured in Taiwan.

2. Disclaimer

All of these tips apply only for the 8399-XXX series of monitors. EXERCISE CAUTION WHEN WORKING ON MONITORS, THE MONO MONITOR HAS 18KV GOING TO THE CRT. Let your techs show you the ropes on monitor repairs, if you're going to be messing around with any live equipment. Be especially careful when doing focus adjustments, aside from personal risk you can smoke your board.
