General recommendations for TV LCD LED repair
Repair of a ROLSEN TV with MST6M181 chassis should begin with a malfunction diagnosis, which involves a careful examination of the external and internal elements of the device. In some cases, visible external damage to elements can suggest directions for troubleshooting and localizing a defect even before the necessary measurements are taken at the control points of electronic circuit assemblies. Elements with visible damage, for example, capacitors swollen after the electrolyte boils, charred resistors in certain nodes of the circuit, as well as ring cracks in the solders, will help the master to guess the causes and possible consequences of the malfunction.
In the absence of any signs of operability, when the ROLSEN RL-16L1002U does not turn on and does not signal anything with the control lamps on the panel, there is a possibility that the power supply module 465-01A2-170005G KB6160, K-1205 12v 4.2a of the TV may malfunction. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. If it breaks, you should check the power elements of the transistors and diodes of the rectifier bridge for avalanche (thermal) breakdown.
The reasons for the breakdown of the power switch in switching power supplies (SMPS) can be different, for example, the failure of semiconductor elements or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as the failure of the BM2596 PWM regulator microcircuit (5) or breaks of resistors in its strapping.
If the ROLSEN RL-16L1002U does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight lamps or their power converter - LED driver. Sometimes, when turned on, the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power supply filter of the LED driver itself, including in the secondary rectifier of the main power supply unit. It should be remembered that when the protection is turned off in order to diagnose a malfunction, there is always a risk of failure of the power elements of the LED driver. After repair, it is imperative to restore all standard converter protection circuits.
Repair of the M181-C3P257-01647 MST6M181-7TS motherboard must begin with diagnosing and checking all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM. Repair of the board and replacement of BM1084 microcircuits are performed if the necessary equipment and the corresponding element base are available. Malfunctions associated with the use of BGA soldering technologies can be localized by the warm-up method.
We remind users again! Attempts to repair the ROLSEN RL-16L1002U TV on your own without the appropriate qualifications and experience can lead to its complete non-repairability!
The main features of the ROLSEN RL-16L1002U device:Installed matrix (LED panel) LTN156AT17-W01.
To power all the internal nodes of the ROLSEN RL-16L1002U TV, an external source of type 465-01A2-17005G Adapter 12v 4,2a is used using BM2596 microcircuits (5).
MainBoard - the main board (motherboard) is an MST6M181-7TS module, using CPU chips: MST6M181VS-LF-Z1, SPI Flash: cFeon Q32B-104HIP, EEPROM: FM24C04A and others.
The F50CT-2DD-E (X) tuner provides reception of television programs and tuning to channels.

Attention! Panel LTN156AT17-W01 LED TV ROLSEN RL-16L1002U is an expensive and unreliable element.
Do not allow any impact on the glass and pressure on the screen surface to avoid damage to the LED panel!
It is also unsafe for liquid to spill onto the screen. Sometimes one drop is enough if it drips down the glass onto the cables to make the TV unrepairable.
