General recommendations for TV LCD repair
ROLSEN TV made on the T. VST26.12C chassis, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Many visible changes in the state of elements make it possible to determine the further direction of troubleshooting and localization of the defect. Electrolytic capacitors of filters with a swollen case, as well as ring cracks formed in the soldering of the leads of heating elements or a layer of coal on burned out resistors sometimes prompt the repairman about the causes of the malfunction and the possible consequences.
Malfunctions of the CEC-LD2407 Rev22H power supply module can be expressed in different ways, for example, ROLSEN RL-16L11 does not turn on at all and the control lamps on its front panel do not light up or blink, all signs of operability are absent. It should be noted that the processor power regulator (converter) may be faulty with the same external manifestations. Diagnostics and repair of the common power supply should always begin with checking the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the mains rectifier, as well as the large 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, PWM controller DP = S01 (6 ), which can only be checked by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If ROLSEN RL-16L11 has no image, but there is sound, there is a possibility of a malfunction of the backlight lamps or their power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are in good working order. When disabling the protection in order to ensure the possibility of diagnosing the 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.
If the motherboard T. VST26.12C 11331 is faulty, first of all it is necessary to check all linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes it is possible to check the health of the MB only by replacing it. Often the MB (SSB) board needs to be replaced in the event of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - TSUMV26KE-LF, YD1517P and replace the failed chips with new ones. Some malfunctions can be associated with the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.
Attention to the owners! Attempts to repair the ROLSEN RL-16L11 TV on your own are not recommended by the manufacturer and can lead to serious negative consequences!

Attention! Panel T156S01-L01 Rev0.1 of the ROLSEN RL-16L11 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.
