General recommendations for TV LCD LED repair
Repair of the ROLSEN RL-19L1003U TV should begin with a careful external examination of all its constituent elements and modules. It often happens that visible damage to elements or connections helps determine the direction of troubleshooting. In some cases, defective elements are visible with the naked eye, for example, charred resistors or swollen sintered capacitors, or electrolytic ones in rectifier filters. The formed ring cracks in the soldering of the terminals of transformers or heating circuit elements are also frequent sources of many malfunctions with a variety of external manifestations.
In the case when the RL-19L1003U does not turn on, does not respond to the remote control and front panel buttons, does not blink lights and does not show any signs of operability, the AY039D-1SF02 Rev1.0 power supply module is probably faulty in this case. If it is working properly with such manifestations, it is necessary to check the processor power regulator (converter) on the motherboard.In the absence of swollen capacitors of the secondary rectifier filter, the power supply should be diagnosed by checking the fuse and, if it is broken, it is necessary to first check all power semiconductor elements primary circuit - diodes and transistors for the probability of avalanche or thermal breakdown.
Power switches in switching power supplies (SMPS) fail for no reason very rarely and, in case of their breakdown, it is necessary to look for a malfunction in the stabilization circuits, checking electrolytic capacitors, semiconductor devices and resistors in the primary circuit. The reason may be a malfunction of the PWM regulator microcircuit, which can only be checked by replacing it with a new or known good one.
If, when the TV is turned on, the image appears and immediately disappears, or is absent initially when turned on, but there is sound and other functions work, there is a high probability of a malfunction of the LED driver (the power converter for the LEDs of the panel backlight M185BGE-L10 Rev. C1). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
In most cases of lack of backlighting, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or more LEDs do not work in one line, then they are broken and should be replaced.
It should be remembered that it is not possible to determine an open circuit in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
Repair of the motherboard T.VST29.A2B 12313 must begin with diagnostics and testing of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
In some cases, the elements of the MB (SSB) board - PCU: TSUMV59XE-Z1 require checking or replacing (if necessary). In cases where a BGA processor is used, its malfunction is usually detected by the local warm-up method.
Owners of the RL-19L1003U TV are advised to contact only qualified specialists with experience for repair! Attempts to repair yourself without the appropriate knowledge and skills can lead to serious negative consequences!

Attention! The panel M185BGE-L10 Rev. C1 of the ROLSEN RL-19L1003U LED TV 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.
