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.

SAMSUNG HTZ210 – INITIALIZATION, UPDATE, FULL SCHEMATIC WITH WAVEFORM DISPLAY – CONNECTOR PIN VOLTAGES - DIGITAL HOME THEATER SYSTEM

Samsung HTZ210 – Initialization, update, full schematic with waveform display – Connector pin voltages - Digital Home Theater System

Samsung HT-Z210 DIGITAL HOME THEATER SYSTEM- Full circuit diagram, Initialization procedure, connector pin voltages Used ICs: KA5Q1265RF (power control), ES7108S (HDMI), CS5345, LA73054, LC87F5CC8A, ES8391SCC, PS9829B, TAS5152 (power amp IC), BTEM39B2SB 9 (Bluetooth)  
 Always unplug the unit’s AC power cord from the AC power source before attempting to: (a) Remove or reinstall any component or assembly, (b) Disconnect an electrical plug or connector, (c) Connect a test component in parallel with an electrolytic capacitor.
 Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The internal wiring may be clamped to prevent contact with thermally hot components. Reinstall all such elements to their original position.
 After servicing, always check that the screws, components and wiring have been correctly reinstalled.  Make sure that the portion around the serviced part has not been damaged.
 Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input terminals and earphone jacks).
 Insulation Checking Procedure 
Disconnect the power cord from the AC source and turn the power switch ON.
Connect an insulation resistance meter (500V) to the blades of the AC plug.
The insulation resistance between each blade of the AC plug and accessible conductive parts (see above) should be greater than 1 megohm.
 Never defeat any of the B+ voltage interlocks. Do not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly installed.
 Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead last.
Operation of Power Block Protection Circuit.  The Condition of Power Protection Active.
1. Voltage of SMPS’s PVDD (+34.5V, J3) is higher or lower than Standards.  Normal Condition Voltage Range: PVDD (+34.5V, J3): about +34.5V
2. Over-current occurs to AMP IC. (Over-output or Output short)
3. AMP IC’s temperature exceeds 150°C.
4. No supply voltage on GATE DRIVER.
Power Protection
1. OTW: Active, IC’s inner temperature exceeds over 150°C.  (Under 2.7V, Protection Circuit wills Active)
2. TAS5352 3TH PIN: Shout down.  (Under 2.7V, Protection Circuit wills Active)
