SOURCE: Hitachi TV screen adjustment

The easy way to fix this: Click 'Menu' on your remote. Then click 'Setup'. Next, you will have to select 'Screen Position Setup'. This will open a screen that allows you to adjust your TV screen position simply by using the arrow keys on your remote. If your TV is anything like mine, this will work.

SOURCE: i have a hitachi tv model 42edt41 year 2004,2005

I have the same tv and had the same problem. I found a posting that stated to re-solder a connection on the cable for the "y" boards. I used this and my tv is perfect now. The part that needs to be re-soldered is the ribbon cables at the bottom of the tv that go from the boards straight to the screen. On the inside of this ribbon cables there are 4 small components that have "100" on them. On each end of each of these pieces, re-solder them. Since I had my tv completely apart I re-soldered all of them across the bottom. No problems now!

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....

Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

Hitachi 43fwx20B

Good Day, firstshot;

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,
1-800-458-6053, www.bdent.com and ask for KIT10 for your Hitachi TV.
If you want some else to do the repair for you call an Authorized Service Center.
Good Luck, big IRISH.
