General recommendations for TV LCD LED repair
Repair of electronic devices, including the ROLSEN RL-24A09105 TV, is advisable to start with an external examination of its external and internal elements. It often happens that visible damage to elements or connections helps determine the direction of troubleshooting. 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 to check the connected elements and assemblies.
In the case when the RL-24A09105 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 V236BJ1-L01 REV.C1 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.When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first of all check the mains fuse. If it breaks, you should check the power elements of the BP62806 (STK076) transistors and the rectifier bridge diodes for avalanche (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 the ROLSEN RL-24A09105 has no picture, but there is sound and the TV is controlled from the remote control, a malfunction is likely in the V236BJ1-L01 REV.C1 panel backlight circuits. LEDs or power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to make sure that the electrolytic capacitors of the rectifier filter supplying the LED driver are in good working order, and check the LEDs by connecting those that are known to be working for diagnostics.
To check the health of the LEDs, as well as the contact connections in the ruler circuit, the panel must be disassembled.
To identify an open circuit in the LED lines without disassembling the panel, a current source is required. It is impossible to open the junctions connected in series with a simple multimeter; a voltage of several tens of volts is required.
On the HFT248CN116H / RON motherboard, in the event of a malfunction, you should first check the operability of all stabilizers or power converters of microcircuits and, if necessary, update the software (software).
If it is not possible to replace the MB (SSB) board, it is necessary to check the serviceability of its elements - MT8223LEMU (1229-BMTL), 4HC4052D, F4558, M21-120,24C16, ME4953, Z1031AIAP1534 ,. Defective components must be replaced.
Owners and users of the ROLSEN RL-24A09105 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to the complete non-repairability of the device!
