Question about Samsung Televison & Video
Has sound but no picture, no menus nothing on the screen at all screen is black.
Posted by Anonymous on
The most of this TV problem is that the inverter transformer built on the main power supply is bad, to fix it, you may replace the transformer , or replace the power supply module.

first check all of your ribbon cables. then check the lvds cable. if this dont fix then you will have to get a service manual and run the panel by itself to determin wich circuit your problem is in. any questions feel fre to contact me....

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

Sounds like main board failure and or power board failure. You need to contact manufacturer and describe problem for tech support. Some of the parts in Samsung TVs have lifetime warranties. Change out of two board is about an hour job and service call is usually comped. Hope this helps. J

Another "same probelm"
My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?
