20 Most Recent Hitachi 61SDX01B 61" Rear Projection Television - Page 3 Questions & Answers

You have a Convergence circuit failure. The Convergence ICs probably need to be replaced. It should be done by a professional due to the adjustments that may need to be done in the factory mode after replacing the ICs.

there is an adjustment called convergence.the convergence setup generates a crosshatch.you need to adjust the red deflection.this is a common thing when the t.v gets moved.the crosshatch or convergence button is mostly on the front control panel.consult the manual for where it is.

There should be buttons somewhere on the TV itself to switch input modes. Look around where the power button is located and see if there is a menu button you can access. Then use channel up/down and volume up/down to scroll thru modes to find input

Here's a link to order the original Hitachi screen assembly for this model (61SDX01B) from a major parts distributor:

Hitachi 61SDX01B Replacement Part Screen Assembly

Replace both of your STKs big black ics If they are STK392-110s upgrade to 180s better ics Electronix has them call 1-800-223-3205

the same thing happend to my 62 in you most likely need to buy a new convergence board which is in the $3000-$5000 price range so you would be better off buying a new tv thats what i did that is the biggest flaw in projection tvs

Sounds like a convergence promblem.

Here are some of the most common symptoms of a convergence problem.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

how old is the set? if its more than 4 or 5 yrs old buy a new one and did u contact hitachi? if not try them depending on how old it is maybe they fix it if not the should atleast tell u the correct problem

it seems that yo got the problem on the video output module.. try to look and check for any defective resistor on this area..

BTW.. when the picture come out did the color was normally detailed..?

Probably one or both convergence amps have shorted.

need to know how to clean a hitachi rear projection screen tv

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

underneath screen remove screws holding screen in place ,it should then slide upward and off.

You can safely clean the mirror and lenses, it can greatly increase your picture if its dirty. If you unplug your tv you can safely remove the back and gain access to the lenses. All it takes is a philips screwdriver. After you remove the back, you can remove the light barrier between the upper and lower half to free up some room. Take a dry scratch-free cloth and wipe the dust from the lenses. If they're grimy, use a little lens cleaner (liquids used sparingly here, electronics don't like liquids, be careful) You can look up into the top and see if the mirror is dirty. A flashlight shined on it will illuminate the dust/dirt if its there. If you don't smoke you likely won't need to clean the mirror, but it may need it. Use windex or similar for tough grime.. I can usually reach up to get the whole mirror but I've heard of using a swiffer mop to reach the top. Removing the screen is difficult but possible if needed to get inside. Don't touch the back of the screen but lightly with a rag to get cobwebs, etc.

I had this same problem and unplugged the TV from the a power strip and plugged it directly into the wall... problem solved.

I read elsewhere that this is called a "ground loop."

DCShelley,

This sounds like an A to D converter problem which may be linked to you convergence amplifiers. I would suggest that you have a qualified TV technician work on this set.

Thank you,

Can you tell me if you have devices connected (like a cable box) via HDMI? It sounds like your aspect ratio change, color lines and loss of pic could be related to a handshake probelm on HDMI with a cable box

If memory serves, no. If I'm wrong, the would be a setting in the menu or the remote to change it from 4:3 to Set by Station or Automatic. Might say Format.

Focus won't help if it is a double image. Sounds like convergence amps need to be replaced. Very typical on these.
