1 Answer

Tuning Promblem My Problem is that the blue color is way off and im not sure on how to tune it back in. i have tried several methods but nothing has worked it seems as if the blue will not move to the left but moves right and up and down. the red is adjustable but the blue doesnt move right(needs to in order to go in focus with the other two colors). If you have any help please let me know. Thank You

You have the typical convergence problem my friend. This is going to involve getting a service manual, locating the two convergence IC's. Then you will need to unsolder then from the printed circuit board. Then you will need to put heat sink compound on the new IC's before you replace them, then most likely, have to do some touch up convergence alignment through the service menu. If you have no solid state repair experience working on printed circuit boards, play it safe and call in a pro to assist you in this repair. Good Luck

Take the cover off and look at the cable that connects the tuner to the main board. Make sure it is connected straight and tight. Make sure all screws in the back are tight, just in case it is a grounding issue. Iff all checks out and you still have issues, replace your tuner.

The retuning process is as follows:

  1. Press the [i+] button on the remote control to display the DIGITAL INFO menu.
  2. Press the BLUE button to display the MAIN MENU.
  3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
  4. Press the RED button to start the auto tuning process for all available digital channels.
  5. Wait for the process to complete.

If you wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

I read for hours, all of the questions and answers everyone had submitted and finally I found an answer where someone suggested checking the video connections. Sure enough the red cable connection was not pushed all the way in. I did some fine tuning and the picture is back to normal.....beautiful......I'm so happy....thanks to whoever wrote that suggestion......

If your recorder is hooked up after the cable box, then it can probably only receive channel 3...the set-top box does the switching, and sends everything to the TV (and recorder) on Ch. 3
