General recommendations for repairing TV LCD
It is advisable to start any repair and diagnostics of the MYSTERY MTV-2602W TV with a careful external examination of internal and external elements, including case parts, a display, buttons, and cables. Sometimes, only by some signs can we determine the further direction of the localization of the fault. In most cases, the repairman can guess the causes of the defect and possible consequences by the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
If the MIP260B-1 power supply module fails, the external manifestations may be different, for example, the MYSTERY MTV-2602W does not turn on at all and there is no indication of the indicator lights on the front panel. When diagnosing and repairing the MIP260B-1 power supply unit, it is first necessary to check the fuse, and if it breaks, the power switch and rectifier bridge diodes should be checked for 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).
It is somewhat more difficult to look for a malfunction in the converter of the power module with an active KKM (power factor corrector).
If the MYSTERY MTV-2602W does not have an image, but there is sound, there is a possibility of a malfunction of the backlight or power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
Repair of the MIP260B-1 inverter is complicated by the fact that in case of any malfunction or emergency, even if the lamps are unevenly worn, protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
In these cases, special care must be taken in view of the risk of failure of the power elements. After completing all repair work, it is imperative to restore the protection circuits for full and safe further operation of the TV by the user.
The Zoran SupraTV motherboard is subject to verification if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the power supply circuits of the microcircuits are working, a software update may be necessary. Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements TV3201-zc01-02, ZR39162PQCG.
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.
