Colors on tv are seperating. looks like double images.

Hi, Try the auto convergence or auto focus to eliminate the problem, if this does not work, you may have to get the TV repaired, the common problem are the power amplifiers that correct the color convergence, that is why you get color shades or ghosts in the images.

How do I adjust the HD quality for a crisper picture? I have tried Magic Focus, but need to know where the sharpness or contrast can be tweeked .

The magic focus function is to electronically align the red, green and blue beams. So all it can cure is colored ghosts. The contrast, brightness and sharpness adjustments are in the customer menu settings. With the remote just push menu and select video or picture adjustments. Those adjustments are in there.

Color ghosts out of allignment

This is a convergence problem that can be as simple as poor connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself.

Let me know if you wish to attempt the repair and I will post additional details and instructions.

Yellow and blue color ruins total picture on 50" tv,can't get rid


I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Color Issues with red ghosts on screen

The suggestions listed would be relevant for 'Ghosting' by itself, however you mentioned you tried to use the crosshairs to line up the images4.gif, which implies convergence - red/green/blue image separation and/or distortion. NONE of the solutions mentioned were anywhere close to the fix for this problem - this us usually cut and dry; convergence circuit failure. Generally, STK ICs are used. (Common parts are STK392-010/020/040, STK392-110/120/150/180, etc.) Most times replacing BOTH of these chips will be enough, sometimes there will be a blown fusible resistor and/or burnt resistors near the chips themselves. If you don't implicitly know exactly what I'm talking about, don't attempt it - take it in to a repair shop. For in-shop repair, this would NOT exceed $250 (EVER) at our location, unless there was more damage done, which is a one in a hundred situation. Good luck!

Hitachi 61SDX picture got dim shows Code 3

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
