General repair guidelines for TV LCD LED
Repair of the PHILIPS 32PFL9606H TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
If the 32PFL9606H TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power supply module. In some cases, only the regulator or power converter of the control processor may be faulty, which is typical for some PHILIPS models. 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 converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the PHILIPS 32PFL9606H does not have an image, but there is sound, the backlight LEDs of the LK315D3LA83 panel or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - CPU: PNX85500, DDR: H5PS1G83E, NAND: H27U4G8F2DTR (MT29F4G08) with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
Before replacing the tuner TH2627, if there is no tuning to the channels, you must first check the supply voltage at its terminals.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.
