General recommendations for repairing TV LCD
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the AKAI LTA-22S01P TV, as well as the external elements of the case. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
In the absence of any signs of operability, when the AKAI LTA-22S01P does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV adapter power module. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
If the power keys of the pulse converter are not equal, you should pay attention to other elements in their bundling, which may be the result or cause of their breakdown.
If the AKAI LTA-22S01P does not have an image, there is sound and the channels switch, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the inverter itself, including in the secondary rectifier of the main PSU. When disabling the inverter protection (to enable diagnostics), special care must be taken in view of the risk of failure of the power elements. After completing all repair work, it is imperative to restore the protection circuits for full and safe further operation of the TV by the user.
Repair or diagnostics of the T.VST26.7A motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, you should update the software (software). If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - TSUMV26KE-LF, 432A-2GLI, 25Q80BVSLG, TDA1517P, 24C32. Defective components should be replaced.
Malfunction of the tuner ET-6T1E-LF-108W-A (TDQ-ATF27WT-F) is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
Once again, remind users! Attempts to self-repair a TV AKAI LTA-22S01P without the appropriate qualifications and experience can lead to its complete non-repairability!

Key Features of the AKAI LTA-22S01P:
Installed matrix (LCD panel) CLAA216WA01.
The MI04BIT12-24-010 inverter is used to power the backlight, controlled by the TE-5005 PWM controller (PWM SOP-16). As power elements of the inverter, keys of the FDS8958A type are used.
To power all internal components of the AKAI LTA-22S01P TV, an external adapter type source is used.
MainBoard - the main board (motherboard) is a T.VST26.7A module, using TSUMV26KE-LF, 432A-2GLI, 25Q80BVSLG, TDA1517P, 24C32, and others.
The tuner ET-6T1E-LF-108W-A (TDQ-ATF27WT-F) provides the reception of television programs and tuning to channels.
