Default OZ9972BN Unprotect

I don't know if this works but found the information on another site.

It shows a 10K, 0.5Watt resistor from pin 22 to ground to override protection.

For testing purposes only.

Default OZ9938 Protection Overide

From one of the repair threads.

Quote:
I was looking at the OZ9938 datasheet and i thought to myself, why dont i try to disable protection just to see if the ccfl's will keep on !
So i shorted pin 3 between the resistor and the capacitor to pin 16 and it worked.
The ccfl's will not go off.

Default Re: TV Repair Reference Library

Vizio TV suck in boot up screen when turned on.


Need a little help here... i've been looking for a similar thread but can't find anything.....

I have a Vizio , model number E3DB420VX, and the mother board number is 3642-1462-0150(7b).

After looking and researching on the internet for the last two days it seems that all arrows point to the EEPROM CHIP.. however i can't find the location of the chip and nowhere on the internet is it listed.... question is, IS it on this motherboard or is it integrated like the emachine computers of old.... yes i'm that old. If someone can point out what the location number might be that would be awesome. The only station numbers i have seen that remotely look like eeproms are U2,6,8,10. All others look like something else. I've contacted shopjimmy and anybody else listed and they told me to come here. So here i am. I appreciate all suggestions...

Danny

Just read this in one of the threads.

Inverter board SSI_400_14A01

Jump pin 7 to ground to override the lamp protection.

Default Re: TV Repair Reference Library

Hi all, I am looking for a bit of help. I have a Samsung UN55F6350 LED. The Screen will not turn on, I have audio. Already replaced the Tcon board, that wasn't it.
I was checking the standby voltage and wasn't getting any on the Power Board harness (plugged in)
while still plugged in, but tv OFF, I unplugged the harness from the Power Supply board to the main board, as soon as I did that the SCREEN turned on - that means my LED's are good... what is wrong, Main board or Power Supply board? assistance would be greatly appreciated.

LG 60uh7700 no picture, no audio. Power led flashes 3 times on turn on and amber led on power board flashes 6 times repeatedly. This appears to be an error code. Does anyone have any ideas?
