I have a samsung hp-t5064 with sound and no picture. I purchased a service manual and went through the check list of solving the problem. It tells you to remove 4 plugs from the SMPS board (cn810, cn809, cn808, cn807) and you should get dc voltages at test pin (Vs 207VDC) and test pin (Va 63VDC). If you do not get these voltages at these two pins you should replace the SMPS borad. My question is when all plugs are unpluged I get Vs 0VDC and Va 63VDC but when I start plugging in the plugs one by one nothing changes as far as voltages until I plug in the CN807 Main board and the voltages are at normal Vs207VDC and Va 63VDC. I am asuming the SMPS board is bad. Would I be correct?

I'm assuming that nothing appears on the screen, not even the menu.
In that what you can do depends entirely of the extent of the damage. If you're lucky it can be just a failed Y-sus board which is relatively cheap and easy to replace. If you're unlucky it's a complex failure, starting with the power source and it will be very hard to diagnose and fix. The only way to know which is to open the tv and test it by measuring the voltages on the power source and the Y-sus board - this should be done by you only if you have at least a basic experience in electronics. If you don't have it then leave that alone , unplug the tv from the wall and call a repairman - if you mess with it the only result will be to make the problem bigger and more expensive to fix.

What could cause this ?


It is not an adjustment of any kind but is a module inside the set having to do with the sweep of the picture information. Specifically the Sustainers

I have a samsung hp-t5064 that show grainy picture with scanning horizontal lines. TV repairman came and looked around the back. Opened it up, replaced some boards, don't know which, I was not


You can also check for poor connections on ribbon cables etc.
Socketed Chips etc.
Modern TV's are more "Computer" than old fashioned TV. You could have memory problems, CPU or timing problems. Power supply problems.
Did the problem occur overnight. Like On/Off... or has it gradually gotten worse. All of these things can be clues. Does a slap on the back cause any glitches or changes to picture. If so then it could be an indicator of a physical problem like a poor connection.
Suggest getting a second tech's opinion before any replacement
Good Luck

My samsung plasma 50" model HP-T5064 cant turn on. what could be the problem?


Make sure all of the cables are very tight on it. The button may actually be faulty, believe it or not. This is common on the model you are speaking of. If the remote won't work either, it is most likely a short.

No picture


It sounds like the backlight is out. If you can see a faint image that changes then this is the case. You either need to send in for repair or replace. It can if you are lucky be a connection. You can try removing the video cable and try another source or cable.
