Have you tried adjusting the brightness control under the lower front left lip? Wouldn't it be funny if that's all it was.
If not, it could be almost anything at this point. It could have smoked and sparked and put on quite a show in the past when it blew, and just do nothing now. It could be as simple as cleaning the connector cables at J4 & J7. Or a cracked joint on pin 1 & 3 of the J4 connector. But you should see some kind of activity on the screen, especially if you smack it on the left side. If adjusting the brightness does nothing, it could be any one or more of 7 capacitors, all of which should probably be replaced anyway.
It could be the flyback transformer needs to be replaced. Not an easy item to find. If that's OK, CR-21 may need to be replaced. If that's OK, you may need to replace any or all of the switching power supply components, including R46, R47, R49, R50, Q9, Q10, Q11, FU1 and possibly others. It could also be CR5 and Q3.
There is also the remote possibility that the TSM PAL and LAG PAL on the logicboard are bad and must be replaced, probably along with U2 on the analogue board.
