How to remove the protection
of the inverter
Several ways to protect shutdown in popular PWM
controllers, LCD inverters.
Attention!
Not all methods tested by the author and may not be recommended
repairers who do not have sufficient experience and theoretical
knowledge.
If anyone broke the TV does not show, be sure to link - the TV is
not switched on
When repair and diagnosis, it is often necessary to check the individual
inverter circuits - power converter lamps illuminate the LCD panel.
Carry out the necessary measurements is sometimes not possible, the
generation of breaks for various reasons, for example because of the
imbalance in the loads.
Together, artists and researches different options for the repair of
conferences were blocking inverter protection in order to obtain
diagnostic capabilities.
Preserved discussion on one of http://monitor.net.ru/forum/lcd-info-
239071.html forums.
Readers are invited to review previously published examples of how to
disable the inverter protection to these PWM controllers:

OZ960
To disable protection for SoftStart input (pin 4 OZ960 chip) should be
forced to file for this input (the pin 4) voltage 1,5V - 3,5V, which will
manage the PWM pulse duration and regulate the output current in the
lamps.

Removing protection for BIT3193:
When the protection is activated the voltage at terminal 5 of about 3, 5 V.
When the voltage at terminal 5, from 0.4 to 2.4V supply and command
"start" PWM operates autonomously, the lamp is not switched off.
TL1451
More information on the KRAB:
Quote:
Remove the TL1451 protection:
- Protection Lock-chip TL1451 (analogue VA9741) is reduced to the simple
action of the output circuit 15 to the "ground".
But if you do it after tripping (eg forceps), nothing happens because the
trigger protection is already locked by the feedback sensor.
- For disaster recovery protection you want to clear off the trigger and
restarting the inverter or a change in level on pin 9 of the chip.
In operating mode, the monitor resets automatically updated protection
trigger.

OZ960
To disable protection for SoftStart input (pin 4 OZ960 chip) should be
forced to file for this input (the pin 4) voltage 1,5V - 3,5V, which will
manage the PWM pulse duration and regulate the output current in the
lamps.

Removing protection for BIT3193:

When the voltage at terminal 5, from 0.4 to 2.4V supply and command
"start" PWM operates autonomously, the lamp is not switched off.
TL1451
More information on the KRAB:
Quote:
Remove the TL1451 protection:
- Protection Lock-chip TL1451 (analogue VA9741) is reduced to the simple
action of the output circuit 15 to the "ground".
But if you do it after tripping (eg forceps), nothing happens because the
trigger protection is already locked by the feedback sensor.
- For disaster recovery protection you want to clear off the trigger and
restarting the inverter or a change in level on pin 9 of the chip.
In operating mode, the monitor resets automatically updated protection
trigger.
