In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

BlackBerry Bold 9700
DISASSEMBLING PROCEDURE 
Remove the battery by prying the bottom of the battery upward. Once the battery is angled up, pull it away from the top of the device. Be sure to remove all power sources before working on electronic devices to avoid harming yourself or the device.
Slide the SIM card from underneath the holding bracket upward toward the battery connector pins. You must remove the SIM card before you can fully disassemble the device. Failure to do so may cause damage to components later on in this process.
Pry off the logo panel with the plastic opening tool. You will hear a snapping sound as the plastic tabs pop out.
Use your T5 Torx screwdriver to remove the two black 5.57mm Torx head screws underneath the keyboard.
Use the plastic opening tool to remove the frame of your device. You will hear a snapping sound as the tabs pop out. Once the case is loosened from the device, slide the case away from the top of the phone.
Gently lift the bottom of the keyboard upward. Pull the keyboard away from the bottom of the LCD display and lift upward.
Remove the two Torx head 4.13mm steel screws with your T5 Torx screwdriver.
Gently pry up the ribbon connector at the top of the phone with a plastic opening tool. Ribbon connectors are fragile. Too much force in the wrong place will damage the ribbon and may force you to replace an entire assembly.
Remove the top two Torx head 4.13mm steel screws with your T5 Torx screwdriver. You should now have two 5.57mm black torx head screws and four 4.13mm steel Torx head screws off to the side. Do not lose them. Lift the clear plastic cover directly upward.
Grip the motherboard by the screen Lift the board away from the base of the housing and vertically up.
Flip the motherboard over so that the LCD display is flush with the surface of your work space. Use a plastic opening tool to gently pry up the ribbon connector located on the left hand side of the motherboard. Be gentle. Ribbon connectors are very fragile.
Use a plastic opening tool to gently pry back the two golden metal brackets at the top of the display.
Use a plastic opening tool to pry the LCD display off the board. The screen is held onto the board by two strong adhesive pads. You will need to pry vigorously. Do not be afraid of breaking the board. The screen will come off well before the board snaps. Removing the trackpad prior to this repair is optional.
Insert the bottom prongs of the new LCD display into the golden slots above the trackpad resting panel. Firmly press the new display into place.
Use a plastic opening tool to bend the golden brackets back into place Press the ribbon connector into place.
