REPAIRING AND NOT THROWING AWAY

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.

Removal of Front Grille
The front grille is fixed to the cabinet with dowels at 6 locations.  * As a screwdriver (for slotted head screw) is used for removal, use special care not to cause damage to the cabinet.
Using the screwdriver inserted in the gap between the front grille and the cabinet (bottom side first), push up the front grille.
Remove the front grille by lifting it up.  When installing the Front Grille, apply quick-drying bond to the dowels and then fit them into dowel holes for secure installation. (The Front Grille will come off easily if its dowels are fitted into dowel holes only.)
Removal of Rear Panel
Remove 14 screws.   Arrow marks ( => ) are printed to identify the screws to be removed.  When assembling the Rear Panel, check to ensure that the packing is not damaged so as to prevent air leakage from occurring.
