General recommendations for repairing TV LCD
Possible malfunctions
- The LG 32CS560 TV does not turn on and does not show any signs of turning on. There are no reactions to the control buttons or the remote control.
In such cases, the fault should be sought first in the EAX64604501 power supply module. It is necessary to measure the secondary output supply voltage, primarily in the standby converter FSL106HR. You should also check the operability of power switches (MDF11N60, STD10NM60N) and rectifier diodes of other converters for the probability of breakdown in PN junctions.
In case of diode breakdowns in the secondary circuits, the converter can operate in emergency short-circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power key can be PWM (PWM) L6599AD (PWM Resonant), HS01G (PFC). They are checked by replacing with obviously good ones.
- There is no image, but there is sound, it responds to the remote. Or the image appears when you turn it on and immediately disappears
These manifestations can be triggered by a power module, or by defects in the inverter, as well as a distortion of the currents in the lamps due to their uneven wear. If all the electrolytic capacitors of the filter according to the inverter power supply are serviceable, you should make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the EAX64272803 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). In cases of complex repairs of MB (SSB) and with the necessary skills and equipment, sometimes it may be necessary to replace its chips LGE2111-T8, 24C08K, 25Q80BVSIG, NTP-7400L, AP7173 H5TQ1G63DFR, LCX244F204, AP2191D, AS324M-E1, MAX3232C and other possible components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
If the TV works normally from external devices, but does not tune into television channels, the TDSS-G101D tuner may malfunction. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
Once again, remind users! Attempts to self-repair the LG 32CS560 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

The appearance of the power supply
Main features of the device LG 32CS560:
Installed matrix (LCD panel) LC320WUN (SC) (A2).
The matrix control uses the Timing Controller (T-CON) 32_47.
To power the backlight, an inverter 6632L-0636A is used, it is controlled by the PWM controller OZ9966SN (24pin), BA10324.
The necessary supply voltages for all nodes of the LG 32CS560 TV are generated by the EAX64604501 power module or its analogs using L6599AD (PWM Resonant), HS01G (PFC), FSL106HR (Standby DIP-8) microcircuits and power switches of the MDF11N60, STD10NM60N type.
MainBoard - the main board (motherboard) is an EAX64272803 module, using chips LGE2111-T8, 24C08K, 25Q80BVSIG, NTP-7400L, AP7173 H5TQ1G63DFR, LCX244F204, AP2191D, AS324M-E1, MAX3232C and others.
The TDSS-G101D tuner provides TV reception and channel tuning.
