You always don’t need to be an engineer or a technical person to repair your printed wiring boards. Some common gadgets like home theater system, computer or any other gadgets have few simple and common problems, and because of that problem, the circuit board mightn’t function properly. So, a thorough inspection visually is required and can save you needless bill and a trip to repair shop. So, don’t get scared to check. And before you check, you need to make sure that the power is turned off on that device.
- Action #1
Eliminate the cover from your devices. The majority of digital as well as computer covers are hung on by four screws, two on each side near the bottom. Eliminate the screws with the screwdriver and set them apart. Lift the cover off.
- Action #2
Inspect to see if all the circuit boards (CB) are connected in securely. You may have just one, but if you have, even more, examine them all. Lots of CB’s have multi-pin edge ports. Relocating can cause them to become loose. Press the cards carefully right into their attaching ports to make sure they’re plugged right in.
- Action #3
Examine private plug-in elements. Few chips, “piggyback” of “child boards” fit into their very own outlets, and can have a loose connection. Draw them out as well as inspect them for dirty or rusty pins, and afterward reseat by pressing them delicately in place, so they are properly seated. The pins should be shiny as well as brilliant if they are tidy and not corroded.
- Action #4
Look for water or foreign things anywhere on the circuit board. In some cases, a paper clip went down onto a circuit card and can make it stop from functioning.
- Action #5
Check additional electrical wiring plugs. Piggy-back and child boards might have a cable link that just presses on. Some of these can work loose in moving.
- Action #6
Search for busted leads on the parts. Some components have small cord leads that can conveniently break off right beside the circuit card or near the component itself. Lightly jiggle larger components with cords to see if a cable might be damaged.
- Action #7
Seek cracks on the motherboard. A hairline crack may not look destructive; however, it can include broken circuit traces.
