    Re: Samsung PN 58B550T2F/T5F - LOOKIN GOOD

    Good deal... Tom,

    The picture is more like the bottom right, but is not so washed out, but not as sharp as the upper left. I tried to adjust out with sharpness or contrast, but does not seam to effect as needed. The picture really is pretty good. Just hate to get it to a good spot, when it could be great. The really great part... was being able to fix it with your help... so cool... I wonder if teams of Doctors feel this way when they save a life... I know... not close... but still neat as it gets.

    Thanks Tom,

    I think if i took a picture you would say... and what is wrong with that picture... and I would say... well... really nothing... just a little pastie and on cartoony type of pictures you can see the shifting ... kind of... almost a little blurry. I can try adjusting the YFR and YRR while watching to see if it helps. I may be expecting to much though.... the menu screen is sharp and clear.

    If you think I am being to critical... just let me know. I am happy to have the unit working... Yeah... and...

    Re: Samsung PN 58B550T2F/T5F - LOOKIN GOOD

    Thanks Guys,

    The x board has a Vb but no Ve. I found the YFR and The YRR but I do not see any test points near the pots. I also do not have the voltages for those, maybe they are in the owners manual, but I do not think so?

    Any Ideas on check points or voltage specs? If not, no worries... you have been awesome in your help.

    Thanks,

    Rob

    HEY TOM AND DRJP,

    THANKS AGAIN FOR YOUR HELP ON THE Samsung. HERE IS THE UPDATE. REPLACED THE MAIN X BOARD AND FIRED IT UP. PICTURE CAME ON... AWESOME!.

    Thanks Tom... DRJP responded as well. I did mean the 4 connectors that connect the boards ... and DRJP confirmed they just need to be eased out. Thank you again for being so kind to respond. I will sloooooooowwwwly work the board to board connectors apart.

    On ward and upward... Thank you as always!

    Re: stubborn black pin connectors on X board Samsung PN58B560T5F

    Thank you ... sir. I thought that might be it, but there is nothing worse than forcing something and having it break I have gotten the jumping up and down ... over such a mistake ... pretty practiced over the years. In this case... practice never makes perfect... thanks to both you and Tom for having the time to help.

    Sincerely,

    Rob

    Hey Tom,

    Here are the tough guys. I know .... you are going to tell me ... Just Pull... bu they are really tight. i do not want to damage anything. I thought they might have a neat little release on them somewhere, but I think I just need to wiggle them. What do you think. As far as your question on the x buffers... I thought that was what the boards to the right of the x main were.

    stubborn black pin connectors on X board Samsung PN58B560T5F

    Here is another probably ignorant question... the black pin connectors on the X board that go to X Buffers ( there are 4 of them) are very hard to pull apart. Am I missing some release. I do not want to force apart? and break something. Is there a trick to releasing or disconnecting the big black block pin connecters - attaching one board to another?

    Thank you

    What can I say... you are a Technology God. I will send my brother a copy of the messages... so he can see the progress. Thanks for making me look like a hero. I will order the board. If you have any suggestions on reliable order points let me know. Thank you again for the lift.

    Sincerely,

    Rob

    Re: Samsung PN 58B550T2F/T5F

    Thanks Tom,

    Can you tell me if there is any way to confirm X Board failure? Voltage on VS and VA is the same with X Board disconnected. I would hate to overuse your valuable expertise, by asking for help on component level diagnostics...it is fun and a journey to uncover a problem... but that journey does not need to be to hell and back ... with my level of experience ... that might be only the half of it .. ha . Thank you for your direction and an X board replacement is a can do... for sure. Thanks again.

    Samsung PN 58B550T2F/T5F

    Hello... thanks to tomcat for getting me here... Hope I am not as lost on the repair side... Have a Samsung plasma PN58B550T2F/PN58B560T5F. My brother asked me to look at it, as I have had success repairing other sets... and luck... it is a wonderful grace when it is on your side... any way. The screen comes on very faint with colors and fluorescence, some of screen blotched out. The PCB (small board under the control board)(I know you know... that was so I communicated it clear) is blinking one green led. The VS voltage is low at 188/187 should be 201, VA is low at 51 should be 55. Both...
