Bir süredir Youtube Kanalımda yayınladığım LCD tamir videolarında invertör korumasını iptal ederek invertörün kapanmasını dolayısıyla monitörün ekranının kararmasını engelliyordum. İnvertör alt yüzeyindeki (smd kılıflı) PWM kontrolcüsünün mantıksal blok şemasını ve örnek devrelerini inceleyerek en uygun iptal tekniğinin bulunması/hesaplanması gereken bu işlem biraz vakit almaktaydı. Çünkü teknik servise gelen hemen hemen tüm monitörlerin PWM entegreleri farklı model numarasına sahipti. Aşağıda listesinin paylaştığım hazine diyebileceğim liste birçok kontrolörün OLP (open lamp protection) korumasının nasıl iptal edileceğinin özet bir listesi.


OZ960
To disable the protection of the SoftStart input (pin 4 of the OZ960), you must force this input (pin 4) to 1.5V – 3.5V, which will control the pulse width of the PWM pulses and adjust the output current in the lamps.
Information was kindly provided by Rottor at the repair forum monitor.net.ru


Another original decision to disable OZ960 protection by pin-10 from AMIT.

0Z960 is a
very simple way to unprotect. put the LED with 10 feet to ground. (6-leg ICs)
OZ964
From the forum member monitor.net.ru KRAB
Quote:

Removing the protection for the OZ964:
At pin 4 (SST – Soft-Start Time), at the moment of switching on, you must hold 1.8 – 2V.

From the participant of the forum monitor.net.ru X1-42
Quote:

OZ964 protection is removed in the same way as the OZ960, LED on 10 output.

d, it works, then no, bu

t it was possible to disable the protection only at the same time for 4 and 10 legs. Separately, the protection was not blocked.

BIT3193
Information provided by the participant KRAB:
Quote:

Removal of protection for BIT3193:
When the protection is activated, the voltage at terminal 5 is about 3, 5 V.
With the voltage at pin 5, from 0.4 to 2.4V and the command “start”, the PWM works autonomously, the lamps are not switched off.

! Removal of protection for BIT3193:
(victor_loza monitor.net.ru)
Option – 1
Through the resistor 2 – 3 kom pin 5 to connect to pin 12 of the chip thus keep the “working” potential of about 1.2 V.
Option – 2
LED as a stabilizer connect to pin 5 on the ground in the direct connection, “stabilize” the voltage on pin 5, to 06 – 08 volts

does not work any option …

I have a second option with LED works. (merkyrio).


TL1451
More information from KRAB:
Quote:

Unlock the TL1451 protection:
– The protection lock in the TL1451 chip (analogous to BA9741) is reduced to a simple action by closing pin 15 to ground.
But if you do this after the protection is triggered (for example by tweezers), nothing happens because the trigger protection is already blocked from the feedback sensors.
– To restore functionality, you must reset the protection trigger by turning the inverter off and on again, or by changing the level on pin 9 of the microcircuit.
In the operating mode of the monitor, the reset of the protection trigger is updated automatically.

To remove the protection, we do an ordinary pull-up with a 12 volt resistor (5.1 … 6.8com) + LED on the 3-leg chip.

PANASONIC TX-LR32X20 STR-H3475 two-time backlighting and protection protection with error 1 (inverter error). When the trench windings are tampered, a small spread is observed in the resistance of the secondary windings within 10 ohms. The lamps are in order (tested on another inverter). The protection was removed by connecting the LED to 18 pins on the ground
