General repair guidelines for TV LCD LED
Repair of the ERISSON 32LES61 TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Based on visible external changes in the state of the components, it is usually possible to determine the further direction of troubleshooting and localization of the defect before making the necessary measurements. Electrolytic capacitors of filters with a swollen casing, as well as ring cracks formed in the soldered leads of heating elements, or a layer of coal on burnt resistors sometimes tell the repairman the causes of the malfunction and possible consequences.
In cases where the ERISSON 32LES61 TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink and there are no sounds and no signs of operability at all, the power module is most likely faulty or there is no processor power on motherboard (a typical defect of some ERISSON TV models). When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
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.
Sometimes the ERISSON 32LES61 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the LED backlight converter V320BJ2-P01 REV.C1, or a break in the LED circuit is possible. In such cases, first of all, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the LED driver itself, including in the power supply unit (power supply unit).
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the rations of their terminals, as well as the reliability of the connections in the connectors and rations of the terminals.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
On the motherboard 5800-A8M260-0020 V.034, 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).
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: MST6E181VS-LF-Z1, FLASH: MX25L3205B requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
Before changing the HFT2-8F / 115CW tuner, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured on the corresponding tuner pins.
Remember! Attempts to self-repair by users of the ERISSON 32LES61 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

Attention! The V320BJ2-P01 REV.C1 panel of the ERISSON 32LES61 LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
