General recommendations for repairing TV LCD
ERISSON with the chassis 8D60, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
In the case when the 37LS16 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, the power supply module is probably defective in this case. If it is serviceable with such manifestations, it is necessary to check the stabilizer (converter) of the processor power supply on the motherboard. In general, 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. Turning off the protection for diagnostic purposes, it must be remembered that in this case there is a risk of failure of the power elements of the inverter. Upon completion of the diagnosis, all regular protection circuits should be restored.
Repair of the motherboard 5800-A8M61A-02 must begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM. Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements T5BS4-9999 SST39VF040. BGA chip malfunctions are usually easy to detect by warming up.
Remember! Attempts of self-repair by users of the ERISSON 37LS16 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

Main features of the ERISSON 37LS16 device:
Installed matrix (LCD panel) LC370WX4 (SL) (A1).
To power the backlight, an inverter 6632L-0457A is used, it is controlled by the PWM controller OZ9966SN. As power elements of the inverter, keys of the K4075 type are used.
The necessary supply voltages for all nodes of the TV ERISSON 37LS16 are formed by the power module JSK4260-022, or its analogs using ICE3B2065, L6598D, L6563 microcircuits.
MainBoard - the main board (motherboard) is a 5800-A8M61A-02 module, using CPU chips: MST9U88L-LF, SPI FLASH: F40-100GCP, EEPROM: 24C64, HYB25DC128160CE-5, AN7820A and others.
The TDQ-6F6N / T11B6CWA tuner provides television reception and channel tuning.
