General recommendations for TV LCD LED repair
ROLSEN RL-23L1003UF TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. According to some external signs of a change in the state of some elements, it sometimes becomes possible to make assumptions about the nature of the defect, as well as to determine the further direction of troubleshooting. Swollen electrolytic or metal-ceramic capacitors, charred resistors, ring cracks in the soldering of the element terminals - all this can significantly help the master to determine the causes and consequences of the malfunctions in the TV.
If the RL-23L1003UF TV does not turn on, does not emit any sounds when turned on, as well as no indicators on the front panel are lit or blinking, there is a high probability of a malfunction in the power module. In some cases, only the stabilizer or power converter of the control processor may be faulty, which is typical for some ROLSEN models. In the absence of swollen capacitors of the secondary rectifier filter, diagnostics of the power supply should begin with checking the fuse and, if it is broken, it is necessary first of all to check all power semiconductor elements of the primary circuit - diodes and transistors for the likelihood of an avalanche or thermal breakdown.
It should be borne in mind that in the practice of repair, it is extremely rare for key transistors in switching power supplies (SMPS) to fail without reasons that should be looked for by checking other components, for example, a key breakdown can provoke faulty elements of damper circuits, or dried electrolytic capacitors or broken primary resistors power supply circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM regulator microcircuit are subject to verification, which it is advisable to check by replacement.
If the ROLSEN RL-23L1003UF TV has no picture, but there is sound, a malfunction is likely in the LED backlight circuits of the M230HGE-L20 Rev. C1 panel. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overestimated ESR.
A malfunction in the backlight circuits often occurs due to an open circuit in the power supply circuit of the LED lines. It is required to disassemble the panel and check the LEDs themselves, the ration of their conclusions, as well as the reliability of the connections in the connectors and the ration of the connector pins.
An open circuit in the lines of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. It takes several tens of volts to open all the junctions, and it is best to use a current source for such purposes.
Diagnostics and repair of the T.VST29.A2B 12313 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.
In some cases, it is necessary to check or replace (if necessary) elements of the MB (SSB) board - PCU: TSUMV59XE-Z1, Sound: 1517P, SPI Flash: 25Q32RS1G. In cases where a BGA processor is used, its malfunction is usually detected by the local warm-up method.
Attention to users! Self-repair of the ROLSEN RL-23L1003UF TV without proper qualifications and experience can lead to its complete non-repairability!

Attention! ROLSEN RL-23L1003UF LED TV panel M230HGE-L20 Rev. C1 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!
