Question about SAMTRON 98BDF 19 in.CRT Conventional Monitor

1 Answer

I have a Samtron 98BDF crt monitor that has a focusing problem. I notice the more I turn down the contrast, the image will eventually get sharper. If I turn the contrast up the image will eventually get blurry. Any suggestions on this weird problem?

Since your monitor is recieving data I would look at your computer hardware for the solution. Did you recently add a program to your computer? Or change a BIOS setting ? Did you have problems with your hard drive?

SOURCE: CRT monitor screen is out of focus.text and other

Hi,

This kind of symptoms can be correct by the focus adjustment at the flyback transformer. FBT mostly has two control knob (Focus and Screen), focus is usually at the top one like in the sample picture below.

Open the back cover of your unit and then locate the FBT. Power on the unit and try to adjust the focus knob.

If the symptoms can't be cured by the this step, this is an indication that the CRT socket is already faulty. You have to replaced this parts and then make some adjustment at the focus knob of the FBT and your unit will back to normal again.

I am trying to clone my lapptop image with a samtron 73.v and the samtron seems dead :-( It says Test Good but does not work


Most laptops have three video-settings:
* output only to internal screen
* output only to external monitor
* output to both internal and external

Select the appropriate video-setting.

Set your laptop's screen-resolution to 800-by-600 by 60Hz -- a resolution that should be compatible with any 15" Samtron monitor.

I have a samtron 97bdf monitor borrowed the logistics office. It still works but the resolution is so bad my eye strains. I adjusted the contrast and light but to no avail.


tyson_gal, You will need to locate something called the FOCUS adjustment somewhere on the monitor. Maybe Samtron has info at their website under Troubleshooting or something similar? hope this was of some help 12fixlouie

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.

Flyback transformers usually have 2 adjustable rods - 1 is for focus the other is for screen (G2) voltage. try turning Clockwise the Screen adjust with brightness-contrast at max. Till you see white diagonal lines, then go back until the lines disappear - then tune the brightness to your desired level.

My samtron 55 monitor becomes hazy and out of focus


Focus and brightness (sometimes called screen control) are usually adjusted in the flyback transformer. Check for a bad connection where the flyback is soldered to the board. This could also indicate a problem with the CRT.
