When I CRT some time ago on display only the middle line (horizontal), the Internet look like. What...... and put in a period of time after the boot turned well.. I had... The refresh rate is 85HZ... Is not before. The refresh rate is too high to display stand? I put the refresh rate adjustment back to 60HZ now, do not know do not have this problem? What happens if you turn on a black line in the middle? I don't want to have the electric iron...... go to the shop to repair, arbitrary price, just want you to buy a new...... which user can solve this problem, I appreciate it.
The fast output foot is broken, welding the foot
How many inches? What's the resolution? Worse, you go to another led!
1, as with a hand pushing to normal, is part of a display board field scanning weld or field scanning Trimming Potentiometer due to poor contact, there is a disconnection signal line.2, the signal line can be removed on the old display, look at the board on the socket is the same, and then look at the end of the assembly line, plug part of the line color is the same as the original location, if the same can be directly replaced.3, if not line problems, see if the motherboard has open welding place, if don't understand, don't do it yourself, the monitor after power failure still exist high pressure, careless will be electric shock.
This is the foot of the output block, because of the prolonged heat and cold alternating, resulting in poor contact. If you have some knowledge of electronics, find a connection tube radiator with integrated block (single) is (note there are some models with discrete components but with radiating plate), the welding foot on it.
