Question about Hitachi 43FWX20B 43" Rear Projection Television

1 Answer

Big time red shift right and flicker on the red.

I have a Hitachi 43fwx20b SN v2l022011 and I saw in a previous message you mentioned STX's and resistors. I do not have SAM's for this TV but would like to repair it if possible.
What items do I need to repair this TV and what resistors go with the STX's? Most importantly where are the STX''s located.
Thanks for your expertice.

    A real pain to replace but fixed the problem. I replaced both devices, I ordered three, thought there would be one for each color. Installed the devices, turned the set on and did the majic focus and wala!

    No problem with the associated resistors.

Check this link to see how the ICs look like. The STK ICs on this TV are located on the right hand side once the back of the TV is removed.
In regards to the resistors, there is not a path how they failed because that will depend on how the STKs failed, I would still suggest to check all the 1.8, 3.3 and 4.7 ohms resistors as well the solder joints around the area.

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.

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.

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.


Hi
The most likely problem is the auto focus module.
A costly repair.
If you are going to fix it ask for a rebuilt one.

the last hitachi that had this problem i fixed it bad finding bad solder conenctions throughout the board that the convergance ic's are on, also i foind some on the two main board in my repair. hopefully resoldering the convergance foard will fix the jitter or jumping around problem. if the picture is too red you can also try turning down the screen control slightly. good luck
