显示器信号线修理（Display signal line repair）

显示器信号线修理（Display signal line repair） 显示器信号线修理(Display signal line repair) My 17CRT, founder of the brand display, due to the use of negligence, close to the VGA Socket line off too much, cause now always will change the color, the yellow and green... Touch down good, but slightly touched the line again... I opened the display, which seems to be where the welding joint... Do not know is good for? How can we put the inside of a line are connected to? I think of a way, your reference. If I use my way to do a good job, to return to a post. Not as I do Never mind. Don't know how in wiring case, first find out about the location of broken blade in the direction along the line, opened the skin around 10cm, and then raised the shielding net, find the blue line and the red line (the two line estimate that you have problems) find the breakpoint, reset, good insulation, restored after use insulating tape wrapped can. Reply: Thank you, Mr. zhang! Oh, the key is my breakpoint on a distance of 1 cm away from the head of VGA... Reply: change is head ah. Reply: you first find the head, the original line opened, please don't break the old control cut a piece on the new head connected with one way, even if there is no such experience, as long as careful not wrong. Answer: Well, thank you! Reply: but the wiring is used in soldering or directly to the two thread around together? Reply: the connection is also very good with regular, The main circuit of 1 red, 2 green, 3 blue line, 6 red, 5 green, 4 blue, and 13 rows of 14 field synchronization signal plus shielding line on the line Reply: but the wiring is used in soldering or directly to the two thread around together? Reply: the whole line together, a line now is not expensive. First, it does not take a long time, will continue to appear, especially often plug the monitor. Answer: of course it reliable welding!! Reply: Oh, thank you! It is welding, not around the above. I found many Caixian inside the core definition of color is not same. The best for head to head for the original. A little patience to spend some time in general can be done very well. Reply: not according to core color definition, according to the actual needs of the first line to define or change. Answer: welding good? Can't find people. Thank you care about... The final exam recently... Don't have time to buy head... I remember 2 years ago when just learning to repair the monitor, the master of the store to change with the signal line, did not change the teacher said you will not be removed? How to remove me on him, so I changed the first signal line. ========================================================================================= Now it is the liquid crystal display signal line can take down the whole, if you display too, go to the computer Town, touch luck. Otherwise, you must open the shell of the display, and then put the signal line inside the lines of different colors, With a million with scale straight to which wire connection which position in the VGA head, down on paper. Then go to the home appliance accessories shop (at least to me this is a home appliance accessories shop) to buy a VGA head, in front of the multimeter to measure out the order of a welding. If you don't say bad welding, just want to fix the display at hand, advise you not to do, because you are not professional, more likely to get worse, or the local processing display to get professional maintenance. Finally, I suggest you every welding line, the trumpet shrink wrap, so even if you end a long, twisted together is not short. I VGA welding line is done, very safe.

Huang Xianjue 13 14 white feet The outer shield shell D15 terminal crimping There is a very suitable welding method is in D15 5~10 at both ends of the pin welding in public together, red, green and blue shield wire twisted together to the public on the ground; 1, 2, 3 feet with red, green and blue wire; 13 yellow line; 14 white lines; the outer shield shell D15 terminal crimping. Macro control in the control system of the projector output port (VGA) Choose the traditional welding method of 3+4 computer video line: (note that the D15 joint must use metal shell) 5 line D15 Red red (R) 1 feet Green green (G) 2 feet The blue color blue (B) 3 feet Line synchronization (H) 13 feet Field synchronization (V) 14 feet D15 terminal crimping wire shell rgb interface Professional display equipment in addition to the D15 interface, BNC interface and rgbhv. RGB welding method Very simple one can pay attention to selection of BNC head 75 euro. D15 RGBHV connection RBGHV D15 The red line of the 1 core. The red shield 6. The 2 green core. The 7 green shield. The blue line of the 3 core. The blue line shield 8. The black line core 13. The 10 black shield. The yellow line of the core 14. The yellow line of the shield 11.

Just pick a ground line (15CRT, of course, the individual exceptions) need to have a certain basis, can not be easily fix, if you have the fun of yourself can make it, if you just want to do a good job that is not pure as save 20 oceans. PS: red is the first root, grey or green second, blue third, white 13, yellow 14 =============================================================================== Monitor maintenance signal line by a plurality of at least? Only connect 7 good rest is redundant and empty feet. ================================================================================ Partial color If the display obvious lack of a color (R, G, BTANK), which is caused by the problem of display signal pathway. Please check the D 15 pin plug, 1, 2, 3, or broken needle. If there is no signal line is broken or the tail plate internal circuit problem. If the display screen is constant for R or G or B, and the adjustment is invalid, this is due to the internal CRT touch or tail plate circuit fault. If the background image is obviously biased towards a certain kind of color, then you can try the OSD menu in the RGB return to normal adjustment. If not, is the tube due to aging.
