hiii.....
If the power supply is supplying the main board with the correct amount of volts, your controller board or your on off switch panel is malfunctioning and needs to be replaced. If its the whole board your looking at a few hundred unless you can find the same tv with a broken screen and just swap parts.The on/off switch board is cheaper but you have to remove alot of interior parts to access and becomes a hastle.
thank u rate me!!!

this model uses 2 different boards--both are not available from Akai (SAMSUNG) look carefully at all the filter caps on the power board--many will be bulged up at the top---last one I did had 20 bad caps---space allowing--replace with higher voltage rated caps---8 were 2200 mfd @25 volt, 4 were 3300 @ 35 volt, 7, 1000 mfd @ 10 volt, and one 1000 @ 6.3 volt---- Sets with 10 digit serial number use one board and sets with 8 digit serial number use another board---I have seen "rebuilt boards" on several sites on the internet for about $115 + S&H---which is about what the original board replacement sold for when they were available.

Hello, the problem could arise from one or two faulty components, but you have to open the back cover of the television and check for the fuse if it is blown up , and if blown up replace with the same rating. Since you have no ideas on television you can contact the manufacturer, but likely component that may go bad are the capacitors, power transistors and regulators...
