Hitachi > 53FDX20B blurry picture

I would start 1st by checking all resistors ie.
RK43 2.2 ohm - 2W
RK47 1.5 ohm - 2W
RK51 2.2 ohm - 2W
RK55 1.5 ohm - 2W
RK59 2.2 ohm - 2W
RK63 1.5 ohm - 2W
If I were you I would also replace the convergence chips. From the above thread it's clear that they are of different quality so they may last different lengths of time (B&D is a good place to buy good quality ones).
I found a free pdf service manual for 53FDX20B on a Polish web site: http://instrukcje.elektroda.net/main1750.html

I too would like to know the solution to this question...we are having the identical problem and Sony doesn't seem to know how to fix it. Although, the picture from the DVD player is perfect, the pictures for cable & video games are terrible. Very frustrating!

The print is readable but blurred, looks smudged and prints pictures blurred too.


Align the print cartridges after installing them to improve print quality. To do this:




1. Load plain paper.

2. Open the Lexmark Solution Center.

3. From the Maintenance tab, click Align to fix blurry edges.

4. Click Print.

Hope that helps.

The images on my computer are blurred


if you use the default dell settings you may experience the problem with blurry images in Internet Explorer. This effect is due to the automatic scaling in IE6 and above. IE tries to resize the images so that everything looks the same as when everything is at smaller dpi, but does a terrible job at it, resulting in blurry and unreadable images. Change the following registry setting from 1 to 0 in order to disable this "feature":
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\UseHR
[1] Adjusting Scale to Higher DPI Screens (MSDN)



good luck with this. please do this, and get back if u run into a problem. also, if this fixes the problem please rate my answer. thanks so much, Joe
