General repair guidelines for TV LCD LED
Repair of the IZUMI TLE32H410 TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
If the TLE32H410 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink, there is a high probability of a malfunction in the power supply module. In some cases, only the stabilizer or power converter of the control processor may be faulty, which is typical for some IZUMI models. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If the IZUMI TLE32H410 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction in the T315S23-L01 panel backlight LED circuit, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
On the motherboard HK-T.MST182V03, in the event of a malfunction, you should first check the performance of all the stabilizers or power converters of the microcircuits and, if necessary, update the software (software).
When repairing an MB board, you need to check its components Flahs: 25Q32. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.
FIRMWARE FOR SPI FLASH -----------> IZUMI TLE32H410, Main: HK-T.MST182V03, Panel: T315S23-L01
In case of failures in Winbond's SPI FLASH software, sometimes they can temporarily restore their functionality after temperature exposure, for example, heating with a soldering station or a lighter. Often this is enough to be able to read the regular software content. After that, the chip should be replaced with a new one.
