power supply or inverter board failing if the power board is the problem it will have blown caps
little cans with puffy tops because the caps have vented if you don't see that then your inverter has died that model id out of production so try shop jimmy. com
first make sure its not an input problem or from an external source.Disconnect all inputs and see if lines are present with no inputs to tv.if lines affect menu and or ON SCREEN DISPAY (top) there is a good chance (SSB) board could be bad .I would start with this board first ,lvds cable (second) and last the logic board (comes only with new LCD)
May be the same problem Magnavox is having with their 27MF231d. I found the fix on this site and it took care of the same problem with my set. Not the easiest thing to do, but it worked. If you do not know how to solder, get some help with this one. If you take it to a Magnavox Authorized repair location, they will just replace the bad capacitor with another bad capacitor of the same type and voltage. The problem is they have a 25w capacitor where a 35w capacitor should be. Mine was bulging, with black tar looking stuff coming out of it. It was obviously bad. Follw the instructions below.
1.Remove all screws around perimeter, one screwat the lower right at (Side A/V), and 2 1”round plastic knob s. 2.Remove back cover 3.At lower left side remove 2 screws forOn/Off switchcut tie wrap that holds wire down for free movement. 4.Disconnect wire connector to side A/V at lower right side 5.Disconnect wire connector to right side circuit Board 6.Disconnect wire connector to left side circuit board 7.Remove the 2 mounting brackets upper left and upper right 2 screws each. 8.Remove 3 screws each side of the metal box in the middle 9.Fold back metal tape off bottom and top of metal box 10.1 wire connector at top of box I left connected 11.Flip metal box over towards top of Tv. Be careful of wire at top thats still connected. 12.On left side in box is power supply board 13.Towards bottom of board you should see the numbers C2081 and C2074 14.Remove the six screws holding down power supply board 15.Flip board down towards bottom of Tv. 16.Unsolder capacitors replace with new 1200uf 35v and 2200uf 35v 105°C radial capacitors 17.Capacitors should be around 1/2” to 5/8” dia. X 1.25 long appox. 2 Wires come out of one end should be .030 dia. 18.Reassemble in reverse order and enjoy
