REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

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.

NEXUS 9 – DISASSEMBLING PROCEDURE – HOW TO REPLACE THE BATTERY – HOW TO REMOVE THE CAMERA

Nexus Tablets - Nexus 9 – Disassembling procedure – How to replace the battery – How to remove the camera

With your fingers, carefully pry off the back plastic casing. Starting at the corners is usually the easiest.
The rear-facing camera seems to fit a little too snugly in its compartment on the rear case; so make sure that it stays connected to the motherboard.
Carefully peel up the copper shielding with your fingers.
Before fully removing the copper shielding, make sure that the blue antenna cable is out of the way of the copper tab.
Using the spudger tool, carefully remove the bottom of the battery from it's location below the logic boards.
The battery is attached to the motherboard with some adhesive, so you may need an Opener to loosen up the adhesive.
Do not pull the battery from the tablet yet, as it is still connected to the motherboard.
Now remove the metal clip covering the battery's connector cable located above the top left of the battery with the spudger.
After the metal clip is wiggled free, the battery's connector cable can be easily removed by just gently tugging it free.
The battery should now lift free of the tablet.
This step is not necessary if you have already removed the battery.
Carefully peel up the copper shielding with your fingers.
Before fully removing the copper shielding, make sure that the blue antenna cable is out of the way of the copper tab.
Unscrew the three 3 mm Torx T5 screws on the antenna board.
This step and the next show the battery removed, but it is not necessary to remove it if you are only replacing the antenna board.
Use your fingers or a pair of tweezers to disconnect the blue antenna cable from the motherboard.
When reinstalling the antenna, be sure to clean it with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.
The antenna board should now lift free of the motherboard.
Remove the three 3mm T5 Torx screws.
Remove the five 2 mm Phillips #000 screws.
Using your fingers, pull up on ribbon connector to expose another ribbon connector below.
Remove the two 2 mm Phillips #000 screws on top of the second ribbon connector.
Pull up the ribbon connector with your fingers.
With both ribbons out of the way, you can now lift the motherboard off of the tablet with your hand.

The camera is attached to the back side of the motherboard via a ribbon cable.
Use a spudger or your fingernail to disconnect the camera from the motherboard.
There is a small board that comes off easily with the camera. It is attached to the camera with a
ZIF connector, and will need to be swapped over to the replacement camera.

NEXUS 7 DISASSEMBLING PROCEDURE –HOW TO REMOVE THE COVER

Nexus 7 disassembling procedure –How to remove the cover


How to remove the display – how to remove battery -  How to remove the cover -  Nexus 7
How to remove Rear Panel

In the following steps you will release the clips (highlighted in red) along the perimeter of the Nexus 7's rear panel. Do not use excessive force while prying the clips. They can be easily broken.
Gently insert a plastic opening tool near the top of the Nexus 7 between the rear panel and the front panel assembly.
Carefully run the plastic opening tool along the top edge to pry the rear panel away from the front panel assembly of the Nexus 7.
Insert the plastic opening tool between the rear panel and the front panel assembly near the power button and pry up at several points along the right edge of the Nexus 7.
Pry up the rear panel along the left edge using the method described in previous steps.
Gently lift and remove the rear panel up off the front panel assembly.
Using the tip of a spudger, push first on one side then the other to "walk" the battery cable straight out of its socket on the motherboard.
How to remove Display 
Peel the upper piece of black adhesive tape completely up off the Nexus 7. Similarly, peel the lower piece of black adhesive tape, but only as far as the copper strip.
It is helpful to fold this piece of tape back on itself to keep it out of the way. Whilst pulling the tape, be sure that the metal shield does not lift up. Hold the shield in place, and if it lifts up, re-seat it in the spring clips around the perimeter of the shielded area.
Use the flat end of a spudger to carefully flip up the retaining flaps on the digitizer ribbon
cable ZIF sockets.
Make sure you are flipping up the white retaining flaps, not the black sockets themselves.
Use the tip of a spudger to pull the digitizer ribbon cable straight out of its socket.
Remove the following screws securing the display assembly to the metal frame:
Thirteen 3.2 mm silver Phillips screws
Two 4.25 mm black Phillips screws.
In 3G models, the two top-center Phillips screws are slightly lower and on top of the motherboard.
Note that the assembly for the non-3G model will NOT fit the 3G model. When looking for the 3G assembly, look for model 'ME370TG', and note that in pictures of the 3G verison the top 2 phillips screw holes are slightly lower than the upper right and left ones.
The display assembly is held in place by a large amount of adhesive on the underside of the large copper ESD shield. In the next few steps, you will be using a plastic spudger to release this adhesive. Work carefully and slowly, making sure to not break the I/O data cable.
Insert a plastic spudger on the left side of the Nexus 7, near the bottom of the battery. Only insert the spudger enough to free the adhesive (about halfway across the Nexus 7) if you go any farther, you may damage the LCD cable. Slide the spudger toward the top of the Nexus 7, releasing the adhesive as you go.
Carefully rotate the metal frame away from the display assembly, minding any cables that may get caught.
You may need to apply heat to the display assembly before lifting it away from the device. Display assembly remains.
