I know this set, I have worked on a lot of Hitachi sets.

You are describing a convergence problem and most likely it uses either 2 or three chips for this. Chips will be black in color with average of 14-18 pins. The fact that you hit it and it works means it is most likely solder connections at one or more of the three or two chips involved.

The repair would entail getting the entire chassis loose and tilting it up so the bottom of the circuit boards face the back of the set---With a magnifier glass a careful look at the pins for the chips on the bottom of the board should show cracked or ringed connections.

If someone finds this the best thing to do is carefully resolder all the pins on them.

If the connections are good it could be a similar problem in the power supply which provides 2 different voltages to them.

Let me know if I can help. I will attach a photo of what a typical chip looks like.

I have Hitachi Ultravision model 46UX25K I was watching in the morning then I shut it down properly by remote control, after few hours I try to turn it on, nothing , no picture just dark screen, I can hear...


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

We have a 50inch ultra-vision, the picture seems to be dim and losing its color


If the set has not been serviced in several years and the picture slowly got darker and or duller looking you may just need to try something simple.

With the set unplugged and the back cover removed look for the three lens----I presume it is a older set called rear projection and not a DLP, the model number would tell me which it is.

If older you will find three large black lens near the middle, clean them free of dust etc with a lens cloth and check the picture again.

Let me know model number if you need further help

I have a hitachi tv model number 50V500A the


go to the menu screen and select picture mode/menu and you should see the option to make changes to colors selection. You can also try and find one of your DVD's that has THX listed on the case. These DVD's have a calibration program included in the disc which can assist you with fixing the color issue

Hitachi 53" rear projection is losing its picture.


If you are not experiencing any shift in colors, it sounds like the power supply is failing since this will affect all three colors.

Hitachi 53SDX01B Rear Projection Television - No Picture


i have a 50" r.p. Hitachi, kinda had the same problem, it would go off at different times and i't hit on the back and get it to come back on,but after awlhile i'd have to hit it more and harder to get it back on till it quit, the menu would come on and would show the video 1 ,3 and that in the corner.After paying $75 for a guy to say it wasn't worth fixing i tried myself. Not knowing what i was doing, i checked all wire plug connections. Found 2 that wasn't seated good replugged them and still didn't work then tried the bulbs, just kinda jiggled all 3 one didn't feel the same so just tapped on it alittle and it popped, i guess back into place, anyway turned on the tv and it worked. Had moved it recentlly so i don't know if that is what moved the bulb. Hope this helps, also mine is a '94 model.
