In worst case you can replace mainboard. Buy one for model B650 and upgrade your tv.

So you say the method mentioned above works? I just quote original article in case if links become damaged one day.
jeroenb wrote: Had the same problem, i changed my model number in the service menu, then it started rebooting over and over again.

I looked here for a solution, but after reading all the messages (took me over one day) i could not find a solution for it. and thought i bricked my tv.
Allot of people with the same problem (not reading carefully)

I found a rather complex and risk-full solution, but being stupid as i am i tried it and it worked!!
be very careful!

Here is what i did;
  • - Disconnect the power cable
  • - (if you use a CI+ PMCIA card)remove the CI+ module
  • - Remove all the screws form the back-end (12, I guess)
  • - Remove the cable on the mainbord (see image down below)
  • - Plugin the powercable (TV is now on standby)
  • - Insert the code for getting into the service menu (info+menu+mute+standby)
  • - the tv starts and the service menu shows up.
  • - Now carefully connect the the lcd cable back to the main board. (be very careful)
  • - Voila, here is the service menu back on screen
  • - Now, recover the model number (eg LB550)
  • - now save, by pressing the power-button (your tv shuts down)
  • - As in a test turn on the tv and see if its working again.
  • - Turn of the tv and remove the powercable
  • - Place the backend together with screws
Its working again!

See the mainbord cable disconnected down below.

First I got rid of the blinking.
Here is what i did;

- Disconnect the power cable
- Remove the cable on the motherboard(jeroenb).
- Short-circuit the legs of the chip(as the WiKi).

- Plugin the powercable
- Insert the code for getting into the service menu (info+menu+mute+standby)
- Now carefully connect the the lcd cable back to the main board.
- Disconnect the power cable

But I do not remember the correct order of these actions!! I've been doing these actions chaotically. At some time, I noticed that there is no blinking. Then do the method jeroenb.

[SOLVED]
I solved it and I made a video on youtube,
very easy, just with the remote control of the TV.
enjoy Panos method!
