    I am working with HP PL4260N CPTOH-0602. TV Has no picture.
    I found Z sus Part# 6870QCZH004B has shorted VS to ground at IPM
    YPPD-018c I replace with stk795-820.Usually tv will have picture after having new IPM.
    This time tv still has no picture. and very cold . All voltages are present. VS 185v
    VA 60v vzbias 100v .Anybody has idea? please

                          Re: HP PL4260N plasma no picture, no sound, no power

                          Working with an HP PL4260N.
                          I have NO nothing! No power, no little red or blue light?
                          Set is stone cold dead.
                          AC runs into the power supply and stops. No little voltages: 5v, 12v, 9v.
                          Nothing.
                          (I use the diode test setting to hear for BEEPS = shorts.
                          Checked the Y-Sus buffer and ground to little pins, NO beeps. Seems all the little IC squares are good?
                          Y-Sus board - replace 1 blown fuse. Still nothing.
                          Checked the 5 little square IRFP 4232's and no shorts - no beeps. All have meter numbers similar.
                          So, I suppose it's the power supply? Of course. But what?
                          I checked ALL the caps and replace a few that seemed questionable.
                          I set my meter on 20K or 200K and test the caps to see if they go all the way to
                          a blank meter screen.
                          A few STOPPED and froze up on numbers. So I replaced those.
                          Still no power.
                          ANY IDEAS?
                          [Plus, I don't have the "remote" for this thing yet. Will order one soon.
                          Send me some advice? - ROSS

                              If your set is completely dead, for now, focus on the power supply and possibly the main board. Disconnect the main board -- do the voltages return? If not, then can we have a photo of the area around the standby power supply on the main board -- it's one of the smaller transformers on the board.

                                  Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
                                  by KYBOSH
                                  Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
                                  No picture but you hear the TV static (white noise) playing loud and clear.
                                  The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
                                  But it seems they didn't get too far and just left it.

                                  When I first took a look I was amazed at how pristine the inside looked.
                                  Its as if the TV had been in a time capsule.
                                  Caps looked like they were just pulled off the self.
                                  Copper coils had no sign of corrosion on...

                                  Saved this beast from the landfill this weekend.
                                  Manfactured July 2013 in Mexico.

                                  I love working on plasma TVs.
                                  Its been a while but I was lucky enough to find 2 this week.

                                  The TV powers on and stays on but no picture. Havent checked for sound yet.
                                  No bulging caps although the insides are pretty dusty and the boards are discolored from many years of high heat.
                                  Will start troubleshooting tonight.

                                  T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

                                  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...

                                  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...
