General recommendations for repairing TV LCD
Diagnostics of malfunctions and repairs of the FUSION FLTV-22W7, as well as other electronic devices, is recommended to begin with an external examination of the external and internal elements. Many visible changes in the state of the elements make it possible to determine the future direction of the troubleshooting. Experienced repairmen are well aware of how ring cracks in soldered terminals look, swollen capacitors, and other causes of problems in electronic devices.
If the FUSION FLTV-22W7 does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If there is no image when you turn on the FUSION FLTV-22W7, or it appears for a second and disappears completely, but there is sound, most likely either the backlight or their power converter (inverter) are faulty. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit. 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 necessary to restore all standard converter protection circuits.
On the CVMV26L-B motherboard, in case of a malfunction, you should first check the operation of all the stabilizers and power converters of the microcircuits, and also, if necessary, update the software (software). In cases of attempts to repair the MB board (SSB), it is necessary to check the health of its elements - CPU: TSUMV26KE-LF; EEPROM: 25F40; which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
Attention! For users and owners of FLTV-22W7 TVs who do not have the appropriate qualifications, knowledge and experience, we strongly do not recommend attempts to self-repair in order to avoid negative consequences that can lead to complete non-repairability of the device.
