You will need a service manual to get the correct part number, I tried to cross with my NTE data base no luck, went into ebay site punched in the original numbers came up empty.

to remove the back cover of samtron 56 v monitor is very simple.
locate the 2 bottom screws of the cover, remove them. pull slightly back the cover holding the bottom and about half an inch gap will be seen. insert a flat screw driver straight down through the upper side hole with your left hand and hit the head of the screw driver with your right hand. a slightly big sound is heard and that side is disengaed. repeat he same with the second hole. and you have done it. try.

SOURCE: To open the Samton 45Bn crt monitor

turn off power.

Get a long philips screw driver and remove the base and all fixing screws. some are hidden behind blanking plates and the com off with a sharp knife and a getle lifting at the join.

After all screws are removed the lie the screen downwards and start to pull away the backing.

you should get the case apart easily.

You must be aware of the tube holding a full charge at its end. DO NOT touch this at any point. The only thing you should try to inspect is the fuse or adjustment to the focus slant contrast etc.

Mosfet check


1. Switch your multimeter to the Diode test position.
The following steps are for an N-Channel MOSFET.
Hold the Black lead to the MOSFET's source terminal.
2. Touch the GATE terminal momentarily with the Red lead.
3. Then touch the DRAIN terminal with the Red lead without touching the GATE terminal with your fingers.
The multimeter should show a low reading now. (The MOSFET is now ON)
4. With the RED and BLACK leads still connected to the DRAIN and Source terminals of the MOSFET, now touch the GATE terminal with your finger. The Multimeter should immediately show an open cct. (The MOSFET is now OFF)
This is a very simple way to test a MOSFET.
