General recommendations for TV LCD repair
SUPRA with LS09 JUG7.820.990-2 chassis, like other TVs, it is advisable to start repairing with a careful examination of external and internal elements and modules. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localization of the defect before the necessary measurements are taken. In most cases, the repairman can guess about the causes of the defect and the possible consequences by the characteristic signs of typical defects in TVs, for example, the formed ring cracks in the soldering of the element terminals, swollen capacitors of the rectifier filter, charred resistors and other circuit elements.
In cases when the SUPRA STV-LC2610W 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 operation when turned on, - most likely the power module is faulty or there is no power processor on the motherboard (typical defect of some SUPRA TV models). Diagnostics and repair of the common power supply should always begin with checking 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.
As a rule, switches in switching power supplies (SMPS) are quite reliable and rarely fail without reasons that should be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM microcircuit is checked by replacing it with a known good one.
If SUPRA STV-LC2610W has no picture, but there is sound and the TV is controlled from the remote control, a malfunction in the display backlight units is likely. The lamps or the power converter - inverter may be faulty. Often in such cases, when the TV is turned on, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the inverter, and check the LCD lamps by connecting external and obviously serviceable for diagnosis to the connectors. If, when diagnosing a malfunction, it is required to turn off 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 completed, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
In cases of attempts to repair the LS09 JUG7.820.990-2 motherboard, 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. Board repair and replacement of CPU chips MST6E181VS-LF-Z1, Flash EN25Q32 are carried out with the necessary equipment, and the corresponding element base. Malfunctions associated with the use of BGA soldering technologies can be localized by warming up.
Remember! Attempts to self-repair by users of a SUPRA STV-LC2610W TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!
