How to use this Guide

This guide is divided into seven sections. Start with the section marked

chassis has several different versions that are NOT covered in the service manuals.

Instructions to Start Service:

1. Obtain model, serial and symptom.

2. Review service bulletins (section 2), for common fixes. If Service Bulletin states that

repair is common, complete repair as indicated. Otherwise, proceed to section 3.

3. If the previous steps do lead to a clear diagnosis, then proceed to the flow chart in

section 3 to help assist you in determining the correct PCB’s to order.

4. Place order through Samsung Parts Department.

Note: Distributors DO NOT carry PCB’s, so backorder with no eta will result. Parts

Department will not accept an order for PTV parts without a serial number because

correct ID cannot be assured.

5. Parts will automatically ship 2nd day.

6. When installing parts (refer to section 6 -Assembly/Disassembly), repair alignment

or adjustment will be necessary.

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.
