Aerospace Printed Circuit Boards and Plane Wiring Repair

광고 Final month, I had obtained approximate 2~5 nos of defective liquid crystal display displays on a regular basis from prospects lived in a residential space occupied by 20000 individuals. I’ve by no means received such a very good harvest certainly. How a lot wages do I get from the repair solely? Unbelievable! It’s $6400 roughly which calculates from common $80 x 80 nos liquid crystal display monitor 샷시수리가격.

I can let you know that roughly 40 % of complete defective displays are straightforward to be repaired usually and the remainder is a bit time consuming however it’s price to carry out digital part analyzing, testing and substitute. As soon as you bought the offender, you solder it out and substitute the brand new half and solder it again on the circuit board.

One of the vital vital and important methods in servicing liquid crystal display monitor is the SOLDERING approach which can convey you quick simply and rapidly. I imagine most repairers will agree with me.

Let take few real soldering examples as follows:

Case 1: Compaq FP731 shutdown from few seconds to couple of minutes

Answer 1: Re-solder the suggestions circuit of the ccfl inverter part C215, C216, D201, D204, R215, R246, R218, D206, C242, D210, R234, R243

Case 2: BenQ T705 received show shutdown after energy on for few second

Answer 2: Solder out four nos. shorted C5707 transistors and solder new transistors again.

Case three: Dell e151fp ( equal to Acer FP553 Chassis ) No energy or energy on then shutdown shortly

Answer three: Solder out the defective C605, C707, C703 capacitor, the defective energy ic UC3842B, defective resistors R613, R623, R615, defective transistor Q601, defective diode D604= 1N4148 and fuse F601. Solder the brand new components again into the circuit.
