General recommendations for repairing TV LCD
It is advisable to start repairing the FUSION TV with the CV182H-E chassis with a careful external examination of both internal and external elements. Many visible changes in the state of the elements make it possible to determine the future direction of troubleshooting and localizing the defect. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
In the absence of any signs of operability, when the FUSION FLTV-32F18 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. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors 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.
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.
In cases where the FUSION FLTV-32F18 TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of an inverter (converter for powering the backlight) malfunction. When you turn on the TV, the image may appear briefly and immediately disappear. It must be borne in mind that with such manifestations, the lamps themselves also fail, the malfunction of which can be detected by replacement, by connecting to the connectors for diagnostics that are known to be serviceable and suitable in power. It is necessary to take into account that in cases of inverter protection shutdown (in order to be able to diagnose) there is a risk of failure of the inverter power elements and take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its Winb25Q32 chips and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
- Remember! Attempts to self-repair by users of the FUSION FLTV-32F18 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!
Repair MainBoardThe appearance of MainBoard TP.VST59.P83 is shown in the figure below:
TP.VST59.P83
The TP.VST59.P83 motherboard is combined with a power module and is an independent device made on the basis of the TSUMV59Xxx multifunction processor. Repair of such a board must begin by checking the power batteries, as well as the operability of voltage converters and linear stabilizers, necessary to provide power to certain processor nodes, in particular: + 1.2V core power, built-in DDR + 1.8V memory and Stand- by 3.3V. The power supply voltage of the LCD panel is 5V or 12V, depending on the type of panel used, it is necessary to check directly on the LVDS connector.
CV182H-E can be used in TVs:
FUSION FLTV-32F18 (Panel TC315FJE1), FUSION FLTV-32L22B (Panel MT3151A05-2), SUPRA STV-LC3225AWL (Panel TH315B041 R213E), SUPRA STV-LC3225AWL (Panel TB315B201), SUPRA STV-LC46990FLH (Panel TC460FPE5).
