General recommendations for repairing TV LCD
Repair of the SONY KDL-15G2000 TV is advisable to start with an external inspection of all its constituent elements, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. In some cases, visible external damage to the elements can suggest directions for troubleshooting and localizing the defect before starting the necessary measurements at the control points of the nodes of electronic circuits. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a hint in the assumptions about the causes and consequences of the malfunction.
In the case when the KDL-15G2000 does not turn on, does not respond to the remote control and the front panel buttons, does not blink light bulbs and does not show any signs of operability, most likely the adap 16v / 3.9a DC A 1194 498 A power supply module is faulty. When diagnosing and repairing an adap 16v / 3.9a DC A 1194 498 A power supply, you must first check the fuse, and if it breaks, you must check the power switch and rectifier bridge diodes for an avalanche (thermal) breakdown.
If a breakdown of the power switch of the flyback converter of the power supply unit is detected, it should be remembered that it does not fail without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller that can only be checked by replacement, as well as others semiconductor elements (diodes, transistors, zener diodes).
In cases using a power module with an active KKM, troubleshooting is sometimes somewhat more complicated.
If when you turn on the SONY KDL-15G2000 there is no image, or it appears for a second and disappears completely, but there is sound, most likely either the backlight or the power converter (inverter) are malfunctioning. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
Often attempts to repair the PWB-IV40194T1A9 inverter are hampered by the fact that the fault diagnosis is complicated by the operation of its protection, which is designed to turn off the inverter in emergency conditions - when the lamps are depressurized, breaks or short circuits in high-voltage connections and other emergency situations. Lock protection to localize the defect is popular among repairmen.
All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
Repair or diagnostics of the motherboard 8 597 590 00 BTP-HC401. A2 1 870 681 12. 1 727 575 must begin by checking the power stabilizers. If necessary, you should update the software (software).
It should be remembered! Attempts to repair the SONY KDL-15G2000 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!
