    RCA Projection TV Blurry Picture

    RCA Senium rear projection Model HD61W140 Chassis ATC311. Cannot complete auto convergence. I get a message that a sensor failed. The picture is a blur across the entire screen. I do not have a service manual. I can get to the service menu but cannot read it due to the blur. It is an old TV but had a great HD picture when operating properly, Any ideas on what to do?
    Thanks,
    Thorerik

      You could start by removing the screen frame and cleaning the mirror and lenses.
      Did I leave the soldering iron on?

          How is the overall convergence? are the red & blue lined up with the green. If its a convergence issue there could be a open fuse neer the flyback caused by broken solder connections on the flyback transformer.

              I looked around the flyback and didn't see anything obviously fried. The overall convergence is off on the entire picture. When looking at an active TV broadcast channel you can see the representations of the red, blue and green images.

              I guess what I really need is a Factory Service Manual for this model (free if possible). Can anyone help me?

                  There are 3 fuses near the flyback transformer (I believe they are brownish color) one of them could be open.

                      this link might give you some help
                      also the service manual is on RCA cd-rom disc and you'll either have find a pdf dump of the disc or a RCA ATC311 cd-rom disc for servicing schematics or alignment data

                          I don't have access to the rca manuals right now so I could'nt cross the manual to the chassis.
                          I did'nt work on that model very often, most likley on convergence board, check if there is +22 and -22 volts on J19700 if its there, check the transistors on the convergence board. I seem to remember replacing parts on this board.

                              T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                              by Tr0ll
                              Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                              The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                              Original T-con:
                              Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                              First replacement T-con:

                              I thought it might be t-con and ordered new t-con from china(supposedly tested)...

                              SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                              by JJAAMM
                              This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                              Problem
                              TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                              Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                              by TR103
                              Hi, I have a Samsung UE50TU with:
                              - sound and backlight, but no picture
                              - when it arrived, it had a picture for a few seconds
                              - it keeps rebooting
                              - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                              - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                              - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                              - without cable between mainboard and lcd panel and with a jumpered...

                              Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                              by Mgiffune
                              I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                              I ordered a supposedly ‘new' Tcon board this time, and                              ...
