General recommendations for TV LCD repair
Repairing a RUBIN TV with an MST6M16 chassis should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Many visible changes in the state of elements make it possible to determine the further direction of troubleshooting and localization of the defect. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred layer of paint on the resistors - all this for the repairman can be a significant clue in assumptions about the causes and consequences of a malfunction.
In the absence of any signs of operability, when RUBIN RB-19K101 does not turn on and does not signal anything with control lamps on the panel, there is a possibility of a malfunction of the TV power module. The power supply regulator of the control processor on the motherboard may also be faulty with the same manifestations. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse in the power supply is broken, in most cases a breakdown of the power switch (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. You should also check the diodes of the rectifier bridge and the electrolytic capacitor of the mains rectifier filter.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (SMPS) it does not fail by itself without reasons that should be looked for by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If RUBIN RB-19K101 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 you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to make sure that the electrolytic capacitors of the rectifier filter supplying the inverter are in good working order, and check the LCD lamps by connecting external and known good diagnostics to the connectors. When disabling 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 standard protection circuits must be restored.
Diagnostics and repair of the 471-01A3-22001G motherboard is carried out by checking the functionality of the stabilizers or power converters of the module chips. In some cases, a software update is required. Complicated repair of MB (SSB) board is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements of the CPU: MST6M16JS-LF, RAM: EM6A9160TS-4G, EEPROM: FM24C64A, FM24C04A SAW - F938912N, F438901N Tuner - CDT-3FP2I2-31, Sound: TPA1517NE, NE5532P, MEA71 ... Malfunctions in BGA chips are usually easy to detect by warm-up.
Attention to the owners! Attempts to repair the RUBIN RB-19K101 TV yourself are not recommended by the manufacturer and can lead to serious negative consequences!
