If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, carefully using your finger find the too hot transistor or, chip; or, use component coolant; spray the too hot component with a component cooler repower the TV, until the screen comes back to normal. To fix: apply white sylicone coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part.

Black Screen with horizontal lines


are u sure that ur not able to see the fone's stand by screen now?its totally black?are u sure that there's no problem with the screen itself,the care guys might have left the screen connection loose. other wise try one thing,Format ur fone. by pressing *#7370# u have press keys once wait for 5 seconds and press the left selectin key [where u get the YES option normally. the fone would restart and lets see are u able to go back on the screen. IF YES then u can set the Sleep mode to off cuz the sleep mode gets inititated after 20 minutes when u keep ur fone idle means u dont operate ur fone for atleast 20 minutes. BUT IN THIS CASE ULL LOSE ALL UR DATA INCLUDING CONTACTS AND MESSAGES ETC.IF U HAVENT TAKEN THE BACK UP EARLIER.so its totally upto u that u want to proceed with this step or u can again show ur fone to the nokia care guys. but they'll charge u cuz obviously after 2 years ur fone is out of warranty
