Question about Hitachi 55FX48B 55" Rear Projection Television

1 Answer

Alignment of the 3 lenses on my hitachi 55fx48b

My tv was working fine no problems then this morning i powerd it up and the darn thing was like 3d i tried the convergince button on the front panal on the hitachi 55in and to no avail it shows 8 + signs plus a box in the center now i can line up the colors somewhat good across the center left to right but because of the top drooping down in the center and bowing up from the bottom in the center i cant seem to get it all straight. what do i need to do to bring the top center up from bowing down and push the bottom down to align it all up. this is very frustrating and if its not an ez fix is it going to be expensive to repair it was new in 1999. i like it alot.

Typical convergence fault that every tube type projection set has had after several years of being used. they are STK ICs and are soldered into place. If you know how to work on solid state electronics, then its not that hard to do, but if you have no training, its not a job for the elctronic layman. It shouldnt cost more then 300 to 350 in most places and thats a bit high from around here.

My tv is not turning on. we just moved from one house to another did the move disturb it

you need to take the front panal off to look and see if all three sockets on ctr tubes are seated all the way. the front panal is the one with the power button,vol and ch buttons and aud/vid hook up. first remove the shiny screws from the back on the sides of tv where speaker grils are. remove the speaker grills. then you have four black screws two on each side of panal and two shiney ones on top of panal. remove all six then remove panal careful not to pull too hard on wires. then making sure tv is unpluged, reach in and under the three tube assembelys, push up under the circut boards right center of where the scoket connects to the tube and make sure they are seated all the way. doesnt take much pressure to push on them so dont kill them. also be careful not to do it off center of the board or board or worse the tube will break. if all is well there, you will have to remove more panals and look a little farther for somthing lose or broken. good luck.

Looks like watching 3D movie(colors) and rounded

This is a convergence problem and is either bad connections on the convergence ICs or defective ICs. If you feel that you can solder, you should be able to repair this yourself. First try resoldering the pins on the convergence ICs. If that fails, replace the ICs. These ICs are large black ICs attached to a heatsink and should be marked STKxxx.
Keep us posted.
