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

If the green is all dominating then it is the red or yellow that is missing in the spectrum. The likely problem is that one of your color guns has burned out. good news is they can be replaced but you have to determine if you have three individual color guns, or one that projects all three colors. (don't skip the easy analysis first though) Check your cables to make sure they are not worn, cut, nicked and most certainly check to see that they are plugged all the way in. Try jiggling the red and yellow inputs while someone watches the screen to see if it flickers. If it does you could just need a new cable. Swapping it out with a known working cable also will work for testing.

U tries go into the tv colors setup and turn down the color RED,might help?Tv could have a problems known a convergence problems,it dead very common problems for old DLP tvs.The tv have R,G,B colors lines mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv have a dead convergence board.The tv convergence board require changes 2 STK convergence ICS and some or all of it resitors too.For fixing the convergence board to solved convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

please check is there any electromagnetic device is near the tv please remove that else picture tube is week and need to replace

Replaced convergence ics. This set is old and if colors especially red are flagging crts are going bad . I would not repair a set this old .

my hitachi projection big screen tv 57SWX20B has a draping affect across top of screen why?

these tv's have a problem with bad crt's you could try to replace the red but a better choice would be all three

This might be something really simple... In a large number of DPTV310 chassis, of which this TV is, the yoke connections where put in place with black electrical tape just below the retaining rings. Job is to loosen the rings, remove the tape and push the yoke back in place and tighten down retainer.. Be careful not to throw off the tilt of the yoke. The adhesive on the tape, over time, gets hot so many time it becomes slippery and allows the yoke to fall away from it's position dulling the look of the image (or focal length) causing the problem you're describing here... It also throws off the convergence - so in attempting to converge it just looks worse. Good Luck Bill

The Hitachi part number for the screen assembly for the 51G500a is KR02844. You can call a Hitachi parts distributor and see for yourself how much those things cost, but I warn you they are not cheap!

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
