I was wondering if it was ic converger or a blown fuse. The picture isn't distorted or out of focus. Just looks like the horizontal tuning is off. Can't see anything.

Does the blue and red crosses move at all ... eather vertically or horizontally. if they move at all then it may not be the chips.. could be a resistor. if the crosses dont move then it probally the ic. these chips run about 7 to 45 dollars apeace depending on type. at our shop we charge around 125 to put in.

Not an easy fix....requires chassis pull, careful soldering and
replacement of parts and fuses.....would you like step-by-step?

first of all take the board out and back sure all the pins are soldered and that one didnt get pushed up out of the way.
then check for solder bridges where you would have solder more than one pin together.
then check the resisters in the circuit that they are all good and then check to make sure everything is plugged in correctly

I don't think is any lamps.
If you are handy try to open the back of your tv, (unplug it first) don't touch anything just yet, you need to make sure you discharge any static left on the power board (the first from your left )Unplug power cord from the board. Take a heavy long screwdriver (Isolated) and lightly, touch a few parts on the board including the thick red wires that go to the lamps. Once that's done its time to put your dexterity at work. You need to lift that board (PD 0074) so that you can check some fuses like F850, F852, etc. for continuity. Mine were out. I had replaced those two and I had tv for another year. Remove the screws that hold the board. Now, this board PD0074 is connected to the next board by two white connectors and one blue. ....lift them up from one side with your finger nail. Don't unplug anything from the power board, just loose some wires so that you can lift the whole board on one edge. Get a voltmeter and set it to check continuity. Mine has a buzz. Look for them fuses if they are bad , ....replace them. (You can buy them at Partstore.com.....punch in "fuses"or "125V 2A")
In my case that was the only problem a year ago. Now I also have the same problem but this trick didn't work for me anymore. The Power Co,. messed me up big this time. In fact the problem with these Toshiba rear proj. is that when the power in your house goes out and comes back right a way in a split second and you don't have a power regulator, guess what : 'red led blinking'
In my case this time the whole power went on and off a few times within 10 sec. and by the time I got to the TV to unplug, it was to late. I think I have to replace the whole PD0074 board....and that's expensive.
Good luck
