General recommendations for repairing TV LCD
Repair and diagnostics of any electronic device, in particular SONY KDL-46X2000, it is advisable to start with a careful external examination of internal and external 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. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
A malfunction of the power supply is often manifested corny - the TV does not turn on, does not make any sounds, does not light up and does not blink with any indicators. In the general case, first of all, it is necessary to check the electrolytic capacitors of the filters of the secondary rectifiers and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
A 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 switch, 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 there is sound and other functions work, there is a high probability of a malfunction of the inverter (power converter for the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter feeding the inverter should be checked. 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 some cases, it is necessary to check or replace (if necessary) the elements of the MainBoard board - CXD0709GB, CXD9816AGG, CXD2097BQ, HTC63LVD1023 SIL9011CTV, SAA7115AHL. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
Once again, remind users! Attempts to self-repair a SONY KDL-46X2000 TV without the appropriate qualifications and experience can lead to its complete unrepairability!
