|
|
How to discharge a CRT without killing yourself works, pitty by this method you can kill the micro or corrupt an Eprom. You must always discharge the crt to the aguadag or the strap on that. Ite aquadag often is not at chassis potential so if you charge the chassis it will reverse bias many things. |

Some are at chassis ground potential, some are not.
Most manufacturers have a (sometimes) spring-loaded "strap" that (usually) also connects to a main chassis ground and a stake on the CRT neck board.
Philips connects to a stake on the main board near the flyback.
Just take your finger nail, pull outward on strap and insert wire, alligator clip, etc.

A pro would use 2 screwdrivers in a crossed sword config, its quick and easy. Even when Philips supplied a spade most techs never used it. |
