Replaced the power supply board on my plasma tv. Now have a snowy picture on all inputs. Green light on the logic board blinks evenly. No puffy caps. Is there another board that needs to be replaced?


After the power supply board replacement, Va & Vs voltage adjustment is a must and necessary for the proper working of the plasma display panel. Do it. If you wish to get some details; check the site linked here. Pull up older posts.

Have a Samsung 50" Plasma, PN50B450. When power is on, red light clicks, nothing happens. I replaced the main power board thinking it was the issue, not so much... Any thoughts????


After replacing a power supply regulator board to any plasma displays, you have to adjust the Va & Vs voltages according to panel specifications. You haven't here specified whether you've done it or not. If not, you have to do it. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Flip card, can be selected by the drop-down list, by the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

42in samsung plasma have sound no picture


Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Good luck in solving the problem also be careful in handling the set because it contain high voltage....

Samsung pn42c430 blank screen can u tell what board def


Depending on what you have done, I can point you in the right direction. I hope!
Switch you Plasma on and look very closely at the screen. In a darkened room, you should be able to see a dull off white glow. If you can see that, the Plasma Display is OK and if there is sound, the processor is working fine which leaves only the upscaler to suspect, it is on the large densly populated board approximately centre of the rear.
If you have no light, the driver stage or power supply is faulty. The display drivers are not replaceable as they form part of the Plasma Display, the power supply however is but usually gives no sound as well.
Without seeing it, that is far as I can go.
Hope that helps.

Picture is not coming on samsung spn4235


Remove the Power Supply cable to Y Main board and check the Vs voltage in Power Supply board.
1. Vs voltage is OK, replace the Logic board or Y Main board.
2. Vs voltage is NG, replace the Power Supply board.
