General repair guidelines for TV LCD LED
Repair of electronic devices, including the FUSION FLTV-32L24B TV, it is advisable to start with an external examination of its external and internal elements. The apparent physical change in some components can sometimes suggest a further troubleshooting direction. Ring cracks in the soldering of leads of heating elements, swollen electrolytic capacitors, a charred paint layer on resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain chance that the power module is defective and needs repair. Sometimes with similar manifestations, a problem can only occur in the absence of standby power. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken 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.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in resistors in the stabilization circuits. The PWM controller chip may also cause a breakdown of the power switch of the converter.
If the FUSION FLTV-32L24B does not have an image, but there is sound, there may be a malfunction of the backlight LEDs of the BOE-HV320WX2-201 panel or their power converter - LED driver.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - CPU: MT8227AAKU, HDMI: LT6633E-P, Audio STA333W, Flash: 25Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
Before changing the TDA18273 tuner, if there is no possibility of tuning to television channels, you should make sure that there are supply voltages that must be measured at the corresponding tuner pins and check the software for correctness.
Once again, we remind users of TV: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of repair of electronic equipment.
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-32L24B , Panel: BOE-HV320WX2-201
In case of failures in Winbond's SPI FLASH software, we recommend that you replace the chip itself with a new one. Sometimes Winbond microcircuits can recover for some time after high-temperature exposure, for example, heating with a soldering station or a lighter, which is sometimes enough to read its contents.
