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.

HOW TO ADJUST CCA ADJUSTMENTS AFTER LIGHT ENGINE REPLACEMENT FOR SAMSUNG HLP 5663W DLP PROJECTION TV

HOW TO ADJUST CCA ADJUSTMENTS AFTER LIGHT ENGINE REPLACEMENT FOR SAMSUNG HLP 5663W DLP PROJECTION TV.

CCA (Color Coordinate Adjustment) SERVICE MODE AFTER LIGHT ENGINE REPLACEMENT TO SAMSUNG HLP 5663W DLP PROJECTION TV

CCA adjustment is needed after changing light engine or digital board.

In DLP TV, even the same RGB color may different depending on the light engine.  CCA corrects the color to achieve the color accuracy.  CCA performs color correction after measurements and inputting the current light engine's data on actual color coordinates for displayed RED, Green, Blue and white color patterns, using a color coordinate measuring equipment.  At this moment color correction is performed on the basis of previously inputted Desired Color Coordinates and Measured Color Coordinates.  Measured data of service engine's color coordinate is presented on the CCA label.  Input the label values to perform CCA color correction. [The condition of CCA will be on the CCA label upon receipt of the service engine]

CCA SERVICE PROCEDURES.
  1. Turn OFF the Power to make the set Standby mode.
  2. Press [MUTE=>1=> 8=>2=> POWER] button on the remote control.
  3. Select [FACTORY>SERVICE>CCA mode on SET.
  4. Switch CCA OFF.
  5. Input the CCA basic engine data to SET.
  6. Input the D-White -x,y values in the coordinates per destination [if necessary]
  7. Select WB SPREAD, then press Enter to activate the WB spread, SET ensuring that you adjust until you get OK sign. After adjusting, exit factory mode.
  8. When the adjustment is complete, check the picture quality.
Performing CCA is independent on current display's resolution and input signal type if you don't measure color coordinat data.  Measuring color coordinate data requires specific equipment  not possessed by service personal, what makes performing manual adjustment impossible.  Adjusting CCA is applied to all the signal mode.  Do not change desired value, because it will be harmful to the color of the set.

INDEX DELAY ADJUSTMENT
  1. Turn OFF the power to make the set Standby mode.
  2. Press [MUTE=>1=>8=>2=>POWER] button n the remote control.
