Most likely a fuse blew when the lamp blew, there is internal fuses on the power supply board on these mitsubishi's, if the fuse is ok though then most likely another component somewhere failed.

Tv will not come on after power outage

Most likely a power spike occurred and if you are lucky it blew a fuse inside of the TV. You will have to dismantle the back of the unit and look for the fuse on the circuit board. It will be most likely a ACG type fuse. You can get replacements at your nearest Radio Shack.

Hi William,

If your problem is a continuous green blinking led light and will not turn on, this is an indication that the DM of your unit try but hasn't booted up and stuck to this fault.
If you have checked fine the fuses on the DM power supply board, you have to check/replaced also the electrolytic capacitors on that board.

11_1_2011_12_36_04_am.jpg has a repair kit for your unit (DM power supply board) that includes these parts.

If you've already replaced the capacitors on that board but still the symptoms still persist, I would advice you to check/replaced the capacitors on the power supply board feeding the DM power supply board. Check also the pico fuses and bad solder joints (cracked, cold, dried solder). Resolder the joints that look suspicious.
Yes, your model has no complete schematic diagram downloadable online. I have a copy of the repair manual that includes the schematic but not a complete one. The power supply's schematic shows only the major parts and the output voltages of the board. Same as on the DM's power supply.
Email me at, I will send you the copy of the repair manual.

Mitsubishi ws-48613 no power

It seems problem of weak capacitors in power supply and deflection board.
If you have little experience of TV repair and good soldering skills, then check above said boards for weak capacitors.
You also need to have service manual of WS48613 which can be obtained from Manual Zone.
Service manual has schematics and technical information of TV to help in repair.
