General recommendations for repairing TV LCD
Repair of the ERISSON TV with the chassis 5800-A8M61A-02 should begin with a careful external examination of all its constituent elements and modules. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
Sometimes the ERISSON 32LS16 TV just doesn’t turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is a failure of the common power module. If it is working properly, you need to check the processor batteries on the SSB (Main Board). In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but there are sound and other functions work, there is a high probability of a malfunction of the inverter (power converter of the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the inverter should be checked. When disabling protection in order to enable the diagnosis of a malfunction, special care should be taken, and after completion of all repair work, it is necessary to restore the circuit and the inverter protection for further safe operation of the TV.
On the motherboard 5800-A8M61A-02, 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). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements Cpu: MST9U88L-LF (Sticker - 86161M K276) Flash: 25F40, Eeprom: 24C64. BGA chip malfunctions are usually easy to detect by warming up.
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.

The appearance of the MainBoard 5800-A8M61A-02 is shown in the figure below:5800-A8M61A-02
5800-A8M61A-02 can be used in TVs:
ERISSON 26LS16 (Panel V260B1-L02 Rev.C1), ERISSON 32LS16 (Panel LTA320WT-L05), ERISSON 37LS16 (Panel LC370WX4 (SL)(A1)), HYUNDAI H-LCD3206 (Panel LTA320WT-L05).
PSU Advanced
The 32LS16 model uses the JSK4210-022 power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, this is a boost converter based on the L6562D PWM controller, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes, when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.
The appearance of the power supply
Main features of the ERISSON 32LS16 device:
The matrix (LCD panel) LTA320WT-L05 is installed.
A converter controlled by the SEM2006 PWM controller is used to power the backlight. As the power elements of the inverter, keys of the type TPC8406-H x 4 are used.
The necessary supply voltages for all nodes of the ERISSON 32LS16 TV are generated by the JSK4210-022 power module or its analogs using FAN7602, L6599D (PWM Resonant), L6562D (PFC), LM393 microcircuits and power switches of the 18N50, FQPF9N50C type.
MainBoard - the main board (motherboard) is a 5800-A8M61A-02 module using Cpu microcircuits: MST9U88L-LF (Sticker - 86161M K276) Flash: 25F40, Eeprom: 24C64 and others.
The TDQ-6F6H / T11B6CWA tuner provides television reception and channel tuning.
