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.

DISASSEMBLY

Remove the rear cover fixing screws indicated and pull the rear cover backwards away from the set.
To remove the speaker box assembly remove the two screws circled and unplug the speaker lead from connector CN2500 on the ‘A’ board. The assembly can then be lifted gently away from its supporting arms.

To remove lift the main bracket rear slightly and slide the chassis away from the bezant. Ensure that the interconnecting leads are released from their purse locks to prevent damage being caused.
When refitting the chassis ensure that the main bracket is located in the beznet guide slots before sliding the chassis forwards. Refit the inter-connecting leads in their respective purse locks.

To place the chassis in the service position, remove the speaker assembly box and insert the main bracket firmly into the T-slot located on the left corner of the beznet as indicated.
To remove the G Board release the clips circled and ease the board gently away from the support bracket.

To remove the D2 board remove the two screws circled, release the clips circled and ease the board gently away from the support bracket.
To remove the D board first remove the D2 bracket by removing the two screws (one on each side of the bracket) and releasing the four clips (two on each side of the bracket). The D board can then be removed using the same method as the G board.

To remove the M2 Board gently release the two clips with a screwdriver and remove the board from its socket vertically.
If the M2 Board needs to be removed for testing when the chassis is placed in its service position, it would be necessary to use an extender board and extension cable as indicated. The Extender board and extension cable are available as a service part by ordering the part number as indicated.
