Question about Hitachi 50SBX78B 50" Rear Projection Television

1 Answer

Lamp flickering my Hitachi 50SBX78B set is having a jumpy picture soon after startup. When my kids stamp their feet on the floor that stops it (not kidding!). Any idea what could be loose? if it's time for new bulbs, are they user replaceable and where is the best place to find them?

Well jumping has nothing to do with lamp so called bulb.
You have what I would call a cold solder joint.
You're going to have to open the set and tap gently to see were it is comming from. If you know anything about soldering they you will know it is not that easy.

Once you think you have found the place were it seam's to be the place were it make's it jump more often, start again to make shure that's the spot and not the hole area.
Then remove the board and resolder,

Good luck

I have a Hitachi 50CX29B 50 in, got it used, it only turns on sometimes i think the power button is lose, and when on the picture flickers occasionaly, is this something that can be fixed easily


The first reason for this fault is the lamp itself, just about to expire.
Check the lamp and then if OK power the projector up with no signal. Does it flicker then? If it doesn't it is a signal lead or the signal itself, if it does suspect the lamp.

Hitachi 50V715 power on/off problem


I would check to see if any of the fans stop turning or don't turn when set turns on. They do have sensors monitoring them and the set will shut down if they are not turning. I believe there are three fans around the chassis.
Hope this helps,

John, Hitachi site is down at the moment, if you remove the clips on the front of the IC`s you will see the numbers of the convergence ic`s, and yes they are a pain to get out, they are probably stk 392-110`s if they are the originals, you`ll have to un-solder 36 pins total to get them out, check for burnt resistors in the general area of the ic`s and replace any that are burnt before turning the set on,be sure to order a tube of "heat sink compound" to apply to the back of the new IC`s, once on the set will probably still look poor, this is normal, run the set for minimum of 15 minutes then push the " magic focus button " inside the front door panel, after it has finished running magic focus it should look great, video-tek

If the power supply board is the only thing affected, I would suggest calling PTS:1-800-844-7871 and give them the model and what you are looking for. This would be the simpliest thing to do. They rebuild boards and maybe more cost affective than trying to repair yourself. Hope this helps!
