ROLSEN RL-17L1002U
General recommendations for TV LCD repair
Repair of a ROLSEN TV with a chassis should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Visible damage to elements can sometimes indicate the direction of searching for a defect even before the necessary measurements are taken. If charred resistors, swollen electrolytic or sintered capacitors, ring cracks in the soldering of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction, as well as check the connected elements and assemblies.
In the case when the RL-17L1002U 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 adapter 12v 4,2a power supply module K-1205, 465-01A2-17005G 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. 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.
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 the ROLSEN RL-17L1002U has no 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. When disabling the protection in order to ensure the possibility of diagnosing a malfunction, special care should be taken, and after all repair work is completed, it is imperative to restore the circuits and the performance of the LED driver protection for the further safe operation of the TV.
In cases of attempts to repair the motherboard MST6M181-T7S 471-01A2-61702G, 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. Complicated MB (SSB) repair is possible only in the conditions of a service center with the necessary equipment. Checking or replacing SA7454, IT6633F-P, TE330C, MP14820S, P4953W, LM1117 3.3, BM2596-5.0 elements requires the necessary training and professional skills in repairing modules at the component level. Problems associated with BGA soldering technologies can be diagnosed by the warm-up method.
Attention! Users and owners of RL-17L1002U TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting to repair themselves in order to avoid negative consequences that can lead to complete non-repairability of the device.

Attention! Panel LTN173KT02 LED TV ROLSEN RL-17L1002U 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.
