Monitor looses contact with computer after about 15 minutes

SAM*TRON 73V N; Model code: GS17VTSS/EDC; Color Disply Unit Type N.: GH17LS; S/N: GS17H9NY700180T; made in Dongguan, China (XINF); July 2005

When monitor got lost contact with computer, also monitor control panel stop working. The screen disappears and small moving window inform: 'the settings are not optimal, try 1280x1024x60'. This is not the truth. After change of actual settings from 1024x768x60 to 1280x1024x60 the same problem exists.
Monitor looses contact with the 3 different computers in exactly the same way. All computers are working properly with another good monitor.
First of FixYa expert, several weeks ago, did advice that in a cheap Novatek, pins 5 and 6 have to be bridged with 50 ohm resistor.
This operation could not be done because there are not any Novatek cheap inside SAM*TRON 73v N monitor. Instead, following cheaps are there, on the small video plate:
cheap no.1:
SE7889 LF
Af22077999E
0521F
cheap no.2:
CM_AN_1.6EK
2005.06.23
A4E9
Second of FixYa expert did advice to take away video card and put it back properly.
When FixYa experts send their advices, the SAM*TRON 73v N monitor was in the workshop, so I was unable to check myself. *** from the workshop said to me that both advices did not help. This reply was send to FixYa. I am having the broken monitor at home now and I am about to put it to garbage.

SOURCE: Monitor Samtron after 10min. looses contact with computer

This problem is caused by the Novatek chip on the video board. Soldering a 50 Ohm Resistor across pins 5 and 6 of this chip resolves the problem on both the Samtron and the Samsung monitors. I have just corrected one of these last night by this means.
Hope that helps

I have lg lcd monitor.the power indication is turn on red..there is no disply..what should i do?


royrocky1989, The first thing you should do is write down on paper, the brand of lcd monitor, model number, date of manufacture" . Second thing to do is visit YOUTUBE and watch 5 to 15 useful video clips of owners/technicians who do their own troubleshooting and repair to their lcd monitor's switch mode power supply/inverter ballast circuits. Then come back to fixya and tell us if you feel confident enough to undertake the restoration of your unit. Search terms at YOUTUBE are "lcd monitor disassembly" and "lcd monitor repair" Good luck with the repair 12fixlouie

Colors reversed on samsung 2220vm


You got a loose connection on your VGA 15pin Socket. everytime the color signal got loose there is a invert video.or missing color signal.Possible cause in which terminals in a bad contacts with wires. preparably the RGB color signal, replace only the 15 pin male socket... which is pin 1 for Red pin 2 for Green pin 3 for Blue..
others pins just trace the signal.. don't worry its color coded.
