I recently had to upgrade an lg6000s firmware to use a CI card
after successfuly upgrading the firmware I turned it off and afterwards it wouldnt turn on again

(Green light blinks about 19-20 times and then remains steady)

I thought it was the firmware so
I tried connecting via terminal as this thread suggests but all it does is download information from the tv
I tried taping escape but it wouldnt go to the command line

any clues ??
Thanks in advance....

The light comes on and the screen brightens a bit, but there is no picture or sound. I read a variety of forums and replaced the capacitors, but it didn't work. I thought that maybe they were soldered wrong because a friend did it, so i bought a whole new power circuit board. That didn't work either, so based off my little knowledge of circuitry and some further digging i thought that maybe enough power wasn't making it to the tv due to a problem in the noise filter, so i replaced that as well. Now i'm sitting here collecting enough parts to build a brand new tv when the two year old tv I've been trying to fix for a year is still broken.

I would greatly appreciate any thoughts or solutions to my problem.

peace out,

Things you need (first fix):
1. A null modem serial cable.
2. A pc with a serial port.
3. A terminal emulator (google "ZOC terminal emulator").
4. A firmware / epk file for your tv (Search for "north american epk" or something like that with this forums search function).

The first fix involves performing these steps:

1. Connect your tv and pc together with the null modem cable
2. Open zoc or another terminal emulator(I think zoc is the easiest)
3. select "serial / modem from the 3rd dropdown box from the top and press configure.
4. press scan then select "9600" as your speed "8N1", "RTS signal off", "CTR signal off" and uncheck "cd signal is valid".
5. press ok and then press connect.
6. turn your tv on and quickly tap the escape key on your keyboard until "mstar#" comes up in the terminal.
7. press enter once then type "swuz"(the command to load the firmware).
8. Select the epk file you downloaded earlier when a window comes up and press enter.
9. If you did everthing right the firmware should start uploading to the tv. It will take a while so do something else while your waiting.
10. Once it finshes uploading wait for the messages to stop and the "mstar#" text to come up. then type "reboot".
11. If everything went right your tv should boot up. You'll need to fix the settings in the service menu to their orignal values. Do that before anything else.
12. Your done! Use your tv!

Hope this helps someone, and sorry for the wait! Please tell me if this works for you!

The second fix is coming soon.
