Hello,

Likely it is appearing because one of the picture tubes (there are 3, red, blue, green) has a focusing voltage that is disproportionate from the others, and is drifting.

I would think that your power supply is beginning to fail, or one of you tubes is beginning to fail.

I have a red X on screen of my Hitachi 57f510 HD tv. What does that mean?


It may have to do with the Magic focus if that model has it: auto convergence and if fails a indication can appear on screen. The Magic focus if in play would be a flashing sequence moving to different areas of the screen in sequence.

Tv will not magic focus, there are two curved sections of blue and green and words are out of focus


55vg825 MODEL DOES NOT HAVE MAGIC FOCUS.
that is a DLP 2005 model.

I am going to make a guess---by the way it is a good idea here to post the actual model number in your description as this saves time and gets you more responses--


If set has magic focus and convergence will not move or is skewed--one or both of the two convergence Ic's this set uses is bad.

Normal life is 5-8 years--a grease to transfer heat from the chips dries out and one overheats and fails.

Most of the Hitachi sets use either 2 STK-392-110 OR 2 STK-392-150 CHIPS---they are the same but the 150 lasts longer.

BOTH chips will need to be replaced if this is the case and any protect resistors around them that are bad also replaced (most of the time just the chips and or 1 resistor need to be replaced.)

Once this is done the set will not have this problem again for 5-8 years.

Depending on your actual model number I may be able to give you general instructions and tell you what you will need if you do the repair yourself.

Keep in mind: usual cost for parts for this repair is about 25 dollars---I can tell you the best place to buy the chips---if you do it yourself there are sites that sell "kits" but for the most part they are much more expensive and most of the parts are not needed.

If you cannot do it shops get 300-400 for this kind of repair---and many will not do it in your home--any good tech can do in home in about 1 hour---I have done hundreds of them 200-250 depending on the set.

Let me know the model number and if you have any questions or need advice reply to this posting here.

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Hitachi 53uwx10b Convergence


You must have the original remote to do complete convergence adjustments. Remote method: Press MAGIC FOCUS button on front panel to start the magic focus. When magic focus is running, press MAGIC FOCUS again. STOP should appear onscreen. Immediately press RECALL or STATUS on the remote (must be pressed before STOP vanishes). The set is now in DCAM (Digital Convergence Adjustment Mode). Manual method: Remove the front grill and access panel or reach around from the back and press the little pushbutton located in the front left corner of the PC board, next to the Digital Convergence Module.
Once in DCAM, the remote buttons STATUS selects green, 0 selects red and ANT selects blue. 2,4,5 and 6 move the cursor and the thumbstick makes the corrections.Make all necessary corrections and then press PIP MODE. The words ROM WRITE? appear onscreen. Press PIP MODE again to store settings. When green dots appear, press MUTE to return to convergence pattern. Press PIP MODE (ROM WRITE? appears again) and then press PIP CH. This will Initialize the internal sensor data positions. When INIT finishes, press POWER on the TV and convergence is complete.
