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 Toshiba case history e-book was written and compiled according to Damon Morrow's in-house service records (or case history) of Toshiba LED & LCD TV failures. This e-book documents a good range of Toshiba LED & LCD TV faults including various memory error's, display symptoms, and power failures. This Toshiba short case history e-book is very easy to use, and it simply lists a fair range of popular problems and secretive fixes for Toshiba LED & LCD TV's. The information contained in these pages are complete with the model number of the Toshiba LED & LCD TV, the board-number of the faulty circuit, and the part-location number of the defective component(s). This Toshiba e-book is a simple and affective reference tool exposing components which have failed causing performance issues with Toshiba LED & LCD TV's. This e-book documents known symptoms on Toshiba LED & LCD TV's such as intermittent power, dead-no power, no start-up cycle, TV stuck on logo screen, no audio, and more. The components which have failed are listed in this e-book, and they are mainly standard parts and IC's. Standard parts such as diodes, resistors, mosfet's, NPN's, and IC's such as memory IC's, control IC's, and switching IC's. The test equipment used while compiling this Toshiba case history information was a standard DVM meter (Fluke), Capacitor meter (uF/ESR) and a 60Mhz digital Oscilloscope (the very basics). The scope was primarily used to troubleshoot IC chips and observe their switching characteristics, while simultaneously using a DVM to monitor how voltage feed back loops respond to the switching. A steady feedback voltage will indicate proper switching, a fluctuating feedback 5

voltage usually indicates a problem with switching. However, in this e-book all of the troubleshooting has been done for you, with the causes and bad parts listed. This Toshiba 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 Toshiba LED & LCD 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. 'case-history'. Note: Below is an example of how the Service-Case-History Records of each Toshiba LED & LCD TV model are laid out in this e-book, and also shows the meaning of each category. Toshiba LED & LCD TV Service Case history Layout Example 1) TV Model Number: Model number of TV issued by TV manufacturer (example 32AV554DB). 2) TV Failure Symptom: The kind of problem the TV is having (example No main power, stand-by only). 3) Faulty Board: Which board inside the TV has the failure (example SMPS). 4) Faulty Board Number: Manufactures Part Number of faulty board (example 75012573). 5) Board Location Number Of Faulty Part(s): The location number of the faulty part(s) on the SMPS-board (example IC801). 6) Part(s) Failure Type: The way in which the part(s) have failed (example IC801 extremely hot).

7) Shop Notes: (If available) shop notes relating to the repair (example IC801 has internal short and R841 was replaced as a service precaution. Also note R118 out of Ohm value and replaced). IC801 is a IPD chip (Integrated Passive Device) (n.a. Means shop notes are not available. 6

The following is just some basic protocols used when servicing a Toshiba main-board or any other main-board.

Quick TIPS MOSFET IC's, STEP-DOWN Regulators & EEPROM's Let's start with MOSFET IC's

7

ImagineX ElectronicS

Many times while repairing main boards on Toshiba LED & LCD TV's MOSFET chips seem to always pose a problem. Sometimes testing the MOSFET IC is simple by checking for shorted pins. But just because the pins are not shorted doesn't mean that the chip works. Many times (more then normal) MOSFET IC's simply quit supplying a source voltage. When this happens a blue or white screen will usually appear on the LCD display, which indicates a source voltage is absent. You can use a scope or a DVM to check the source voltage (a DVM is usually sufficient). To check the gate's switching pulse it can only be done using your scope. Gate pulse is important to check because without it, there will be no source voltage. Step Down Regulators Step-Down regulators also fail quite often resulting in tuner problems and sometimes audio switching errors. Referring to page 7, Pin #1 is the shutdown pin, this means if there is an external over-voltage (OV) this pin will swing to a logic 'low' and stop all of its internal 'step-down' functions. So to check this IC is pretty easy by using the scope, which will indicate if pin #1 is logic high or low (logic high means a problem). Of course another way is to check the output voltage at pin #3 V-OUT. Pin #3 is usually called the monitoring pin as it monitors any threshold change in the feed-back voltage which will affect how V-OUT is performing in relation to the switching of an external FET connected to pin #4 EXT.

Do not overlook these regulators as they cause a number of main-board problems.

EEPROM TRICK

The following information is a known trick myself and other technicians I know have been using for many years on 4th generation SoC Flash/EEPROM's. This method usually works with memory circuits that don't use smart SDRAM's or Flash chips that have cyclic redundancy checks (check-sum errors or Null). I always recommend using a EEPROM programmer, but for tech's who don't have a programmer they can try the following trick for LED & LCD TV's with EEPROM problems. After you have removed the faulty EEPROM and replaced it with a new EEPROM try these 5 steps in the next page after you have the data-sheet showing you the EEPROM's pin configuration:

10

ImagineX ElectronicS

5 Steps 1 With the TV off run a jumper wire between the Vcc pin and the SDA pin 2 Power the TV on (15 seconds), you should see an error message on TV screen (or a warning message) 3 Now disconnect jumper wire starting at the SDA pin then turn TV off 4 Remove the other end of jumper wire from the Vcc pin 5 Now power on the TV, the TV should perform normally. If you want further settings of the EEPROM you just installed you can get into the TV's service-mode and alter various settings. Sometimes you don't have to install another EEPROM because as a jumper is connected to SDA and Vcc this disables the EEPROM (SCL pin to Vcc pin will work also). When the EEPROM is disabled the core processor see's the EEPROM as not being there (removed) so the communications are now cut off. If EEPROM has internal enable problems or SDA problems then it needs replacing.

This concludes Quick TIPS
