General recommendations for repairing TV LCD
Possible manifestations of defects
- The plasma TV PHILIPS 32FD9944 does not turn on. There are no signs of operability. The indicators on the front panel do not shine and do not blink, and the remote control and control buttons do not respond.
In the vast majority of such cases, a malfunction is detected in the power module. It is necessary to measure its secondary output voltages, and if they are absent, check the power switches (MC33368P, PCF8574AT, TEA1507P, PSMN035, MC34067P) and rectifier diodes in the converters for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch can also be PWM (PWM) 312212360046 3122 123 60046. It is checked only by replacing with a known good one.
- The indicator blinks or glows constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the motherboard 31221236001.7 should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). Sometimes it is necessary to check or replace (if necessary) the elements of the MainBoard board - M51V18165F60J, M29W160DT, PCF8591T, MSP3415G 88 V3, HCT573, AD9887KS-140, SAA5801H \ 015 ALTERA, EP1K30FC256-3, CY62126BVLL-70ZI4902I, AM290. In cases where the BGA processor is used, its malfunction is usually detected by local heating.
Owners and users of the PHILIPS 32FD9944 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
Main features of the PHILIPS 32FD9944 device:Installed matrix (LCD panel) FPF32C106128UA-72.
A PLAZMA inverter is used to power the backlight.
The required supply voltage for all nodes of the PHILIPS 32FD9944 TV is provided by a switching power supply using microcircuits 312212360046 3122 123 60046 and power switches of the type MC33368P, PCF8574AT, TEA1507P, PSMN035, MC34067P.
MainBoard - the main board (motherboard) is a module 31221236001.7, using microcircuits M51V18165F60J, M29W160DT, PCF8591T, MSP3415G 88 V3, HCT573, AD9887KS-140, SAA5801H\015 ALTERA, EP1K30FC256-3, CY62126BVLL-70ZI, AM290L184DT
