General recommendations for TV LCD LED repair
Repair and diagnostics of any electronic device, in particular ROLSEN RL-23L1005UF, it is advisable to start with a careful external examination of the internal and external elements. Many visible changes in the state of elements make it possible to determine the further direction of troubleshooting and localization of the defect. Experienced repairmen often guess about the causes of the defect and the possible consequences, for example, by ring cracks in the soldering of the element terminals, as well as by swollen capacitors or resistors burnt out to coal dust and other external indirect signs.
In the case when the RL-23L1005UF does not turn on, does not respond to the remote control and front panel buttons, does not blink the lights and does not show any signs of operability, the power module AY1303A029426 AY039D-1SF01 AY069D-3SF Rev1.0 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. primary circuit - diodes and transistors for the probability of avalanche or thermal breakdown.
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, when you turn on the ROLSEN RL-23L1005UF, there is no image, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the M230HGE-L20 RevC1 panel backlight LED circuit, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the common power supply.
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.
When trying to detect a break in the LED lines, it should be borne in mind that it is difficult to do this without disassembling the panel. For example, a current source is required to open PN junctions connected in series.
Repair or diagnostics of the T.VST29.A2B 12313 motherboard should start with checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
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 - TSUMV59XE-Z1, 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. Usually such defects are detected by local heating of the chip.
We remind users again! Attempts to repair the ROLSEN RL-23L1005UF TV without the appropriate qualifications and experience can lead to its complete non-repairability!
