General repair guidelines for TV LCD LED
Repair of the ERISSON 40LES73 TV should begin with a careful external examination of all its constituent elements and modules. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. In some cases, faulty elements can be seen with the naked eye, for example, charred resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
If the 40LES73 TV does not turn on, does not make any sounds when turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, only the stabilizer or power converter of the control processor may be faulty, which is typical for some ERISSON models. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If there is no image when you turn on the ERISSON 40LES73, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the V400HJ6-PE1 Full HD panel, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
A break in the line of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
In cases of attempts to repair the motherboard 5800-A8M57A-OP20 VER00.02, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - SPI FLASH: GD25Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
It should be remembered! Attempts to repair the ERISSON 40LES73 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

To reduce the backlight current in LED drivers with a TPS61196 controller, it is necessary to proportionally increase the total resistance of the resistors from terminal 10 (ISET) to the housing. The maximum current in each of the six channels (in milliamperes) for the Rset resistor (in kilo-ohms) is determined from the ratio 3992 * 1.229V / Rset. In channels connected in parallel, the currents add up.Repair MainBoard
