General repair guidelines for TV LCD LED
Repair of electronic devices, including the FUSION FLTV-32T23 TV, it is advisable to start with an external examination of its external and internal elements. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in soldering will help the master to guess the causes and possible consequences of the malfunction.
In the absence of any signs of operability, when the FUSION FLTV-32T23 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 power module. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
The breakdown of the power switch of the pulse converter is often triggered by other elements, for example, in the stabilization or control circuits of this key, as well as by the damper elements in its drain and TPI winding.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but the sound is there and other functions work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the panel ST3151A04-1 Ver.2.4).
The lack of backlight often occurs due to an open circuit in the LED circuit. There is a need for disassembling the panel and checking the LEDs themselves, as well as the same contact connections in the connectors and rations of the terminals.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
If the motherboard CV9202H-TPW is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, and also, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
In some cases, they require checking or replacing (if necessary) the elements of the MB board (SSB) - SPI Flash: 25Q64BV; . In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
Attention to the owners! Attempts to self-repair the FUSION FLTV-32T23 TV are not recommended by the manufacturer and can lead to serious negative consequences!

Attention! The panel ST3151A04-1 / Ver.2.4 of the FUSION FLTV-32T23 LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
