samsung txg2046 problems / eeprom / service mode

hello all, I have a samsung txg2046 19'' color tv. a while back after a thunderstorm I found that when adjusting volume etc the tv would turn off/reset. not good but since I have some external speakers with their own volume control on it and use it mostly for video games it didn't matter. Then I tried to adjust the volume the other day and managed to make things worse. Now I get no picture from the av inputs, picture from ant. is ok. I saw a brief picture once while pushing the vol/resetting the tv but it didn't stay.

Anyway I was browsing this newsroup and found that this seems common for samsung (at least the initial problem) and is likly corrupted EEPROM. taking the tv in to be serviced seems silly since it cost $200

5 years ago and now I could get a 27'' for that price. Howevere I love to fix things if I can.

I found the factory mode and was hoping someone might know if there is anything I might change that might enable me to fix the eeprom so that my picture comes back. Any help would be much apreciated .. if i make things worse its not a huge deal since between the vol and no no pic for video in the tv isn't very useful to me.

Model No: TXG2046 Serial No: 3ccj801955z

thanks

ok .. update .. I started playing with service mode a "bit" and decided factory reset wouldn't be a bad bet. so I did that video in video mode was still blank. dang. however when I started playing around in ant. mode I realized that the volume works now!! :) no more resetting. so I fixed that. but does anyone know what all the other options in service mode do? I dont have the service manual. Anything that might get my picture back in video mode?

thanks again

You may need an EEPROM, & Micro! Rono.

Techs just adore those customers who must dick with the service menues, than do not inform the techs that they did so. We have a very high regard for those in-ept personel who go where many professionals will not without the proper documentation. Something akin to checking if the fan is running by digital interface with your hand!!<

Well I got everything working .. looks like it was indeed just corrupted EEPROM settings. So after getting into service mode with the mute+1+8+2+power_on I used both the info from

formatting link
on the samsung chassis KCT52A as well as a bit of luck and managed to find a working set of numbers for the option bytes, specifically byte0: 20 byte1: 554

Since the chassis manual seems a bit dated the info on byte1 didn't jive completely but I now have audio and video like normal, so I am happy. Thanks to all that replied.
