Samsung plasma TV sound but no picture


Both Vs and Va voltage should be checked. As far as audio is OK, the possibility of main digital board fault.

Got sound but no picture on samsung tv model code PN60E530. Help?


Use a flashlight up against the screen to check for picture, if you have a picture, then the inverter is bad.

Sounds like it could be a bad capacitor on the power supply, or possibly on the video out circuit. Bad capacitors are a common problem in Plasma and LCD monitors and T.V.'s.

Sound no picture Samsung 58" Plasma TV Model #: PN58C550G1FXZA


if you are a tech in any aspect, try testing the power points Vs and Va voltages. If not present even with the other circuit boards disconnected the Vs is supposed to be 205v when disconnected like on my tv, it only had 12v and the Va which is supposed to read 56v was reading about 10v when the boards were connected (Y Buffers). With the boards disconnected the power supply will read high voltages, and when connected (try lower first, then try upper, then try together). If there is a voltage drop (significant) that particular board connected is the culprit. If the PSU doesn't read a large voltage like mentioned, try replacing the PSU first.

No picture have sound hp t5064


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?

Samsung HP-T5054 NO pic No sound B


samsung boards are around $200 EACH , usually a bad buffer burns out the Y board , buit yours sounds like a burn power suppy, do a visual of the PS, if looks ok ck for the VA and VS voltages (there is a tag with the values on it) . if the VA or VS is low or missing you will probably need the Y and both Y buffers.
