Re: 42LG5000: Service menu - Tool option 1 codes

After a couple of days, my friend took a look at the VGAMAxx test points as suggested. We compared the results with the information in this thread:

Since the measured voltages looked random, he changed the faulty chip, which I am marking in the attached image. Now everything looks ok and the TV has been working correctly for more than 4 hours.

I'll call this one solved and thank Tom very much for his expert advice.Re: 42LG5000:...

Since I don't have experience measuring a live TV set, I will ask a friend of mine to help me doing that. Don't want to break anything else if there is still hope to save the TV.
I will send the measurements as soon as I get them. Thanks!

Sure....

Re: 42LG5000: Service menu - Tool option 1 codes

Ok. I did as adviced and found a sticker on the screen panel, which says as follows:

Manufactured 08/48
Model T420HW02 V.0
AU Optronics XXXXG

The "Tool option 1" is now set to the following values, which seem to match the panel:

Tool option 1 ... 9490
Module ... AUO
Inch ... 42
Tool ... LG5000
Intelligent Sensor ... 1
SRS HD ... 1
Module version ... 0

But no luck. The TV image is still distorted...

Hi all! I have been messing around with the service menu of my 42" LG LCD TV. I got there by simultanously pressing MENU on the TV and on the REMOTE for 5-10 seconds. In this menu, there is an option called 'Tool option 1'.

The thing is I've changed the settings there while trying to unlock the USB port for movie playing, and the TV picture went totally bad. After doing some research over the internet, and even downloading the service manual, I found out that each combination of the parameter settings generates a code. Each TV model is supposed to have its unique one.
