Samtron Monitor 56V Display Problem

solution 1 please replace the horizontal output transistor in near to line output



solution 2 in case you changed the horizontal output when the problem not solved follow this.

monitor line output transformer burned replace them its kept on monitor from mother board to connect thru picture tube. very carefully to change the part because its have a storings voltage capacity in heavy.
solution 3 check the signal cable

Did you check the adjustment setting on the brightness and contrast?
These two setting can be moved and stop the CRT from displaying,
Please move these two setting to MAX and see is there any image on the display.

connect another cable as follows
1-red
2-green
3-blue
4-gnd
5-gnd
6-red gnd
7-green gnd
8-blue gnd
9-+5v from display card
10-stand by
11-synchronus ground
12-sda
13-hsync
14-vsync
15-scl
the numbers of pin are given
under pin

Please check whether the power cable is properly inserted...

The power button of this model fails with time.You need 2 press it tightly and hold it till the LED is on....

try this...


Hope this helped...

check the capacitors inside the monitor, as they may be broken, and they start screen up, just change em and it should kickstart fine

this is due to the abnormal 5v supply to micom.check upthe 5v line.

1.poewr LED blinking or not.if in case LED blinks one time. problem in LOT .Cheak horzontal Transistor also.
1a) power out put voltages
2.drypoints in neck board.
3.cheak display cable.

HI all,

The problem im facing is, im using a Samsung samtrong 56V monitor, there is horizontal line appearing in the both ends of the monitor screen which gives a mirroring effect. ( for ex: if ya move the cursor on that it will show multiples of cursors displayed in that line only.)

Please suggest me a method to solve this issue. are there any patch avail for this if so please send a link to download.

thanks a lot

its seems you have a cold solder.

change the 5v regulator 7805 which is the supply for microprocesor
