SAMSUNG PROJECTION TV SERVICE GUIDE
Section 1 - How to Use This Guide
Important Points:
1. Most adjustments can be made using the remote control. However, in certain cases,
a "special remote" is required. This remote is included with each macro kit except the
PCJ522R series (not required). If you need this special remote you can order it from
Parts Department. (refer to section 2, service bulletin)
2. Option Byte: The firmware controlling the microprocessor may need to be changed
after Main PCB or Macro Kit is replaced. This is done by setting the option bytes.
Improper setting can cause symptoms including improper audio operation, menu
selections, or mechanical operations of the control panel door. Refer to the service
bulletin for correct settings.
3. The DTV input will not be recognized unless a DTV signal is applied to the
component input before DTV mode is selected.
4. Macro Kits are universal, PCB's are not. A macro kit can be used for any version
replacement within the same model group. However; all macro kits are the newest
version, which may require the connectors be modified to ensure compatibility with the
CRT PCB connectors (refer to section 3).
5. Screen Replacement: Samsung PTV utilizes 2 screens; an outer Sunscreen and an
inner Tint Screen (Fresnel & Lenticular) sandwiched together. FYI, some models do not
have a Sun Screen. To order either of these screens under warranty, contact
Product/Technical Support for authorization. Note the name of the individual authorizing
the replacement for future reference, if needed.
6. CRT Burns: Permanent "burn ins" can occur if the set is used in any mode where
the screen is always dark or a screen image is static. This requires replacement of all
three CRT's. Contact your RSE on how to handle this service. This is normally not
covered by warranty, so special approval must be granted.
7. Auto Mileage: We will pay $0.50 per mile travel time without special approval, up to
50 additional miles beyond the 25 miles required by contract. However; you must
provide proof, such as Internet driving directions or similar verifiable map and attach it to
the claim when submitted.
8. Macro Kits are always version 1 chassis. This means if an older version unit
previously had a Macro kit installed, parts ID via the serial number will be invalid.
Chassis version can be identified by the color of the connectors. White = original
version, black = version 1.
9. Returned parts: All parts must be returned with a description of the defect attached.
Failure to do so will result in delay in processing and credit. Also, include one copy of
the NARDA so warranty status can be confirmed.
