Case History Vol.1 Samsung LED TV: Memory Problems, Power Problems, Display Problems Documented Service Records - All Level Technicians For Intermediates, Professional Technicians And Advanced Students Documented Service Records – All Level Technicians Power Faults - Display Faults - Memory Errors The following information in this Samsung LED TV case history e-book was written and compiled according to Damon Morrow's in-house service records (or case history) of Samsung LED TV failures This e-book documents a fair range of Samsung LED TV faults including various memory errors, display symptoms, and power failures This Samsung case history e-book is very easy to use, and it simply lists a fair range of popular problems and secretive fixes for Samsung LED TV's The information contained in these pages are complete with the model number of the Samsung LED TV, the board-number of the faulty circuit, and the partlocation number of the defective component(s) This Samsung e-book is a simple and affective reference tool, revealing components which have failed causing performance issues with Samsung LED TV's This e-book documents known symptoms on Samsung LED TV's such as Stand-by power only, dead-no power, no start-up cycle, WIFI error's, no video, faulty audio, and much more The components and IC's which have failed are listed in this e-book, and they are mainly standard components and IC chips Standard component failure include diodes, resistors, MOSFET's, IGBT’s, FET's, and capacitors NOVACOM NOVACOM NOVACOM IC chip failure include memory IC's, control IC’s, regulation IC's, gate IC's, etc The test equipment used while compiling this Samsung LED TV case history information was a standard DVM meter (Fluke), Capacitor meter (uF/ESR) and a 60Mhz digital Oscilloscope (the very basics all technicians use) The scope was primarily used to troubleshoot IC chips and their I/O signaling, and drive circuits The scope was also used to test feedback-loops, start-pulses, duty-cycles on SMPS boards, as well as serial-clocks, gatecircuits, memory and bucking control on the main board However, in this ebook all of the troubleshooting has been done for you, with the causes and bad parts listed This Samsung LED TV e-book is for technicians of all levels, there are no complex diagrams or detailed graphics involved This e-book is not a case history of troubleshooting and circuit evaluation (as with my other books) This e-book is a simple case history of Samsung LED TV parts failure Again, all of the troubleshooting work has been done for you and compiled in a simple and easy to follow format This e-book is written text information correlating to shop records There are no pictorial graphics or illustrative diagrams used in this e-book as it is not required i.e 'casehistory' Note: Below is an example of how the Service-Case-History Records of each Samsung LED TV TV model are laid out in this e-book, and also shows the meaning of each category NOVACOM NOVACOM NOVACOM Samsung LED TV Service Case history Layout Example 1) TV Model Number: Model number of TV issued by TV manufacturer (Example UN46H6203AFXZA) 2) TV Failure Symptom: The kind of problem the TV is having (Example Start-up attempt, then immediate protect mode) 3) Faulty Board: Which board inside the TV has the failure (Example SMPS) 4) Faulty Board

identifying the package style of all LCD/LED/Plasma/OLED IC chips and board connectors TV IC Chip Package Style's & Board Connectors Used in all LCD/LED/Plasma/OLED TV's Brief reference information to help identify the package styling of a few modern TV IC's and various board connectors The following sections of information contained below pertains to all flat screen TV's (regardless of technology i.e LCD/Plasma/OLED) and its purpose is to accurately reference the physical package styling of a few contemporary IC chips and the Names of board connectors found inside all LCD, LED, Plasma, and OLED TV's In some isolated cases (depending on the IC manufacturer)the part number of the IC doesn't always reveal the physical package styling of the chip This means when the chip arrives at the shop the physical body(package-style) of the IC chip is either shaped differently, or too big or small in which case the IC won't fit properly on the circuit board and this is also the same scenario with board connectors as well The aim of this brief section is to get familiar with TV IC's by identifying their correct package style, and identifying the names of different board connectors also NOVACOM NOVACOM NOVACOM Section 1A of IC Package Styles: Most popular IC packages inside LCD/LED/Plasma/OLED TV's Small Outline Package (SOP), Thin-Small Outline Package (TSOP), Thin-Shrink Small Outline Package (TSSOP), Shrink-Small Outline Package (SSOP), Micro-Small Outline Package (MSOP),Quarter-Small Outline Package (QSOP), Heat Sink-Small Outline Package (HSSOP) NOVACOM NOVACOM NOVACOM Section
