Question about Computers & Internet
I have been having the problem of picture cu-out recently - the screen starts up ok, but picture appears to cut out after 10 seconds. I can see the picture if I shine a torch on the screen so it appears to be the back lights. I thibk its something to do with their power supply maybe. If Ipress the auto tune button the back light comes on for a few seconds again then backlight goes out. please advise what could be the problem component to change. I guess this problem is not the CC tubes as I have a second identical screen and if I swap the power supply I get same on the other screen os its the power supply I assume. There are mainly passive components caps 1 or 2 electrolytics and one main chip BA9741F and 2 smaller ones BE4U14 - msny thanks
Did you try disconnecting it from the power for a few hours to hard reset the unit? Did you check the power connectors?
