General recommendations for repairing TV LCD
It is advisable to start any repair and diagnostics of the PHILIPS 19PFL3606H / 60 TV, as well as other devices, with a careful external inspection of internal and external elements, including case parts, a display, buttons and cables. 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. Electrolytic capacitors of filters with a swollen body, as well as ring cracks or a layer of coal on burned-out resistors formed in the soldered terminals of the heating elements, sometimes tell the repairman the causes of the malfunction and possible consequences.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when it is turned on, there is a certain chance that the power supply module 715G4899-P1A-000-002U 996510043919 is faulty and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of processor power, which is typical for certain PHILIPS models and happens much less often. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters 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 N-FET converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
In most cases, a breakdown of the N-Fet converter key does not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective chip PWM LD7750RGR (7), AO 4602 (8) from the manufacturer.
It is somewhat more difficult to find faults in the converter of the power module with an active KKM (power factor corrector).
If the PHILIPS 19PFL3606H / 60 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the inverter itself, including in the secondary rectifier of the main PSU.
The diagnosis of the 715G4899-P1A-000-002U 996510043919 inverter can be difficult due to the protection being triggered by the designers to prevent negative consequences or fires in emergency cases, for example, during short circuits or breaks in the lamp power supply circuit, as well as their possible leakage. To make the necessary measurements at control points or to take the necessary waveforms, repairmen have to block the protection circuits in order to be able to diagnose.
It should be remembered that in such cases there is a risk of failure of the power elements of the inverter and to take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
The motherboard 715G4796-M1B-000-004X must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up constantly. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary. Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - TAS5717 (48), MT5135AE, tuner TDTK-G731D 996510043918 and replace failed chips with new ones.
Once again, remind users! Attempts at self-repair of the PHILIPS 19PFL3606H / 60 TV without the appropriate qualifications and experience can lead to its complete non-repairability!

Main features of the PHILIPS 19PFL3606H device:
Installed matrix (LCD panel) LM185WH1-TLG1 code 131 p / n: 932228373682.
To power the backlight, a converter is used, combined with a power supply, controlled by the DA9689GN PWM controller. The transformer 80GL19T-933-DH is installed in the inverter converter. As power elements of the inverter, keys of the AO4602 type are used.
The necessary supply voltages for all nodes of the PHILIPS 19PFL3606H TV are generated by the 715G4899-P1A-000-002U power module, or its analogs using LD7750RGR microcircuits (7).
MainBoard - the main board (motherboard) is a 715G4796-M1B-000-004X module, using TAS5717 (48), MT5135AE chips and others.
Tuner TDTK-G731D 996510043918 provides the reception of television programs and tuning to channels.
