Question about Hitachi 42EDT41 42 in. HD-Ready Plasma Television
Have a 42 inches plasma TV, and when I turn it on it works fine for several minutes then pictures goes away gradually not immediately but audio is fine
Is the t.v new or its been some years that you bought it?Have you checked the DC voltages leaving the power supply? If not, let's try that now.
Put your red lead on each pin leaving the power supply one at a time, with your black lead on any exposed chassis metal for ground. Stick that red lead down into the connector so the lead makes contact with the pin.
Be sure the TV is turned on.
It can be a fault in the screen if it is under warranty i suggest you contact the shop or supplier.

If the set is still in warranty, call for warranty service. If not and you feel comfortable working on the set, carefully open up the back and reseat all of hte cables and connectors. This can be caused by marginal connections inside the set.
Keep us posted on your progress and results.

I think you have dry solder joints on the tv. Either on the chroma board, the vertical scan board, the line output board, or on the focus board. If you are going to do this yourself please take all necessary precautions against electric shock and discharge all capacitors that you can as a stray spark from one can cause damage to your tv and yourself. If you are not able to do this find a competant technician. Good luck.

SOURCE: black line on middle of screen
Hopefully you still have under warrantee. If not, sorry. This line if memory serves me right is because the tv has 2 picture panels on each side of the TV (they join up together to make one picture). Toshiba did not realize that the panels will start slipping thus creating this fine line from the top of the screen to the bottom. They have revamped the newer models and placed glass to adhere the panels together. Even though my TV was under warrantee I got a new one and have had this one for 1/2 year and now the picture just blew (there is sound but no picture.)
Take your TV back if it is under warrantee.
