Master Electronics Repair !: REPAIR / SERVICING TV SUPRA STV-LCWL

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.

As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.

In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts. Happy repairing! Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of.

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.

With the same symptoms, the stabilizer converter of the power supply to the control processor may be faulty. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the filters of the secondary rectifiers if any , you must first check the mains fuse. When it is broken, the power elements of the transistors and diodes of the rectifier bridge should be checked for avalanche thermal breakdown. Power switches in switching power supplies SMPS fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit.

The reason may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the BP power supply for an overstated ESR.

To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel. It is impossible to detect a break in the line of LEDs without disassembling the panel with a simple multimeter.

The composition of the modules. Often, according to certain external signs, it may be possible to draw certain conclusions about the reasons for the failure of certain elements of the circuit even before taking the necessary measurements, which will make it possible to determine a further algorithm for troubleshooting and localizing a defect.

Supra stv lc2677wl v4l05 firmware cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred layer of paint on the resistors - all this for the repairman can be a significant clue in assumptions about the causes and consequences of a malfunction.

If the TV does not turn on, none of the indicators on its front panel are on or blinking. Also, if the TV does not respond to the remote control and buttons, does not emit any sounds and any signs of operability when turned on, there is a certain probability that the LK-OPA power supply module is faulty and it needs repair.

Sometimes a problem with similar manifestations can occur only in the absence of processor power, which is typical for certain SUPRA models. It is advisable to start diagnostics of the power supply module by checking the condition of the electrolytic capacitors of the rectifier filters and the mains fuse.

Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in a breakdown state in such situations. In most cases, breakdowns of keys in switching power supplies SMPS do not occur without 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 broken resistors or punctured semiconductor elements in the stabilization circuits.
