    Also, it takes about 10-15 minutes before it gets to this bright white screen. When you first turn the tv on, it actually looks normal.

      Also, it takes about 10-15 minutes before the screen goes white. The first few minutes after turning it on, it the screen looks normal with normal color.

        I have an Insignia NS-L42Q-10A tv and I have the layer of white on the screen and when I put the menu up that still has the layer of white. I have been looking for the T-Con Board for it but can't find the exact one that matches my part number. TX-5542T06C12-96M-DL40000-03000-05 that's the number on the white barcode sticker on the T-Con Board. Can I use a different board? I sent in a request to Shopjimmy a few days ago but they still have not gotten back to me. Thanks, JR

            Re: Insignia NS L42Q 10A

            The QFP on my T-Con board is marked AS15-HF. What does the -HF mean?
            Can I replace it with any AS15-__ ? Are there AS15-__ with bad -__ or date codes to stay away from?
            I plan to order 1 from Ebay, just not sure which -__ to get.
            I have read thru many posts but I did not find these answers.
            Thanks for the input

              Spec sheet:
              Exposed pad type package is not going to be easy to remove from the board.
              See PDF to see what the exposed pad means.

                Thanks for the fast reply!
                If i am understanding correctly I need to replace the AS15-HF with another exposed pad part -HF or -HG.
                If I find the part would you recommend a heat gun for removal - possibly cut all the leads first?
                The part removal maybe somewhat difficult but I know what to expect now. I am sure I would have damaged the board not knowing about the exposed pad part.
                Now I am more worried about installing the part than removing it.
                Thank You for the Part data and exposed pad part info.

                  Re: Insignia NS L42Q 10A

                  Hi, I have a Insignia NS-L42Q-10A that when I turn it on the light changes from red to blue but no picture and no sound, checked the power suplly and the fuse was ok but on the plug were there should have 12v and 24v didn't get any voltage readings, the 5v was ok. Should I go and get a new power supply or there is more testing to do? Any help would be appreciated.

                    Post some photo's of your circuit boards. Looks initially like the mainboard is not sending power on signal. Need to measure the voltages on the connector going to the mainboard and give the pin names and number of each.

                        We need to know the pin name of each pin and follow by the Voltage reading of each pin so we can easily see what you have and do not have when TV is OFF and when power switch is activated.

                                Are you completely sure that pin 11, 12 for 5V are only putting out 3V?
                                Where is pin 10 PS-ON Voltage reading?

                                  Let me try and help you. You could just fill in the blanks. Plug in the Tv to the ac and take these voltage readings WRT chassis ground. ie the BLACK probe on the chassis.
                                  Pin No. Descriptor Voltage
                                  pin 1 ON/OFF
                                  pin 2 PDIM
                                  pin 3 +12V
                                  pin 4 +12V
                                  pin 5 GND
                                  pin 6 GND
                                  pin 7 GND
                                  pin 8 24V
                                  pin 9 24V
                                  pin 10 PS-ON
                                  pin 11 5V
                                  pin 12 5V
