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!

Use a spudger to pry the bottom cover off the Apple TV. It may be necessary to use two spudgers (one to hold it open while you pry with the other one)
Carefully remove the bottom cover from the unit
Remove the pink thermal pad. (I already removed mine) Remove the five philips #1 screws securing the heatsink and logic board to the upper casing.
Using a screwdriver (flathead) or a spudger, pull the power cable out of the logic board Now with a spudger or flathead screw driver, CAREFULLY remove the LED connector. Do this very carefully as this connector is extreme fragile, and easily damaged.
Use a flathead screwdriver or spudger to tilit the logic board to an angle so you can grab it with your hands Holding the logic board by it edges, lift it up slightly. And remove Thats all. The logic board has been removed. Just follow the steps (Step 1-5 in reverse to install the board)
The chip with the grease on is the Apple A4 chip. The thermal pad took the silkscreen off, so its hard to read. The The black ball surrounded by meta is the IR Remote sensor. In the third picture, the power connector and LED status connector are shown.
