General recommendations for TV LCD repair
Repair of a ROLSEN TV with RSAG7.820.1653 VER.A chassis should begin with a careful external examination of all its constituent elements and modules. Often, based on external signs and the nature of damage to elements, it becomes possible to draw some conclusions and determine a further algorithm for searching for a defect before taking the necessary measurements at control points. 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.
Malfunctions of the power supply module JSI-220402 P / N: 47131.220.0 / 0112805 can be expressed in different ways, for example, the ROLSEN RL-22B01 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. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. If it is broken, the power elements of the transistors BA8B4S, BA9A1S and the rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
Power switches in switching power supplies (SMPS) fail for no reason very rarely and, if they break down, 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 LD7575PS PWM regulator microcircuit, which can only be verified by replacing it with a new or known good one.
If, when turning on the TV, 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 inverter (backlight power converter). In such cases, the lamps, the inverter and the common power supply module must be checked, in which the electrolytic capacitors of the rectifier filter supplying the inverter must be checked. It should be remembered that when the protection is turned off in order to diagnose a malfunction, there is always a risk of failure of the power elements of the inverter. After repair, it is imperative to restore all standard converter protection circuits.
The RSAG7.820.1653 VER.A motherboard must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or is on continuously. In such cases, if the converters or power regulators of the microcircuits are working, it may be necessary to update the software. In cases of complex MB (SSB) repairs and with the necessary skills and equipment, it may sometimes be necessary to replace its AZ1084S 3.3E1, Z1015AI, Z1021AI, K24C32, 4558CM-E1, HS9453, CD1517CP, TDA9886TS, ME4953 and other possible faulty components. Malfunctions associated with the use of BGA soldering technologies are usually easily diagnosed by the warm-up method.
Owners and users of the ROLSEN RL-22B01 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The main features of the ROLSEN RL-22B01 device:
Installed matrix (LCD panel) LTM220M1-L01 SD.
The JSI-220402 inverter is used to power the backlight lamps, it is controlled by the TL494C PWM controller. The keys of the AOD484, AOD417 types are used as power elements of the inverter.
The formation of the necessary supply voltages for all nodes of the ROLSEN RL-22B01 TV is carried out by the JSI-220402 power module, or its analogs using LD7575PS microcircuits (PWM flyback).
