Question about Hitachi 57SWX20B 57" Rear Projection Television

1 Answer

Bad picture TV is 4 years old. Picture suddenly became green tinted and very dark. Did magic focus. Did not help. Contrast, brightness, etc. all on 100%, but still very dark picture. Sometimes no color,just a green tint. Is this a major problem, too costly to repair???

Dark background blue tint

Try the Magic Focus option on the menu screen found under "Picture". Make sure the TV is on for 20 minutes before activating this option. It is also best to run this when the room is dark.

Roger, if your contrast (sometimes called picture) and brightness controls are at max you can increase the tubes brightness by turning the "screen control" clockwise, be advised a little turn goes a long ways, don`t crank it too far or you will get retrace lines, you will have to remove the back from the set and follow the red wire down from the tube to the "flyback transformer" on the front of the flyback are 2 controls, focus and screen, do not move the focus control, this should fix your problem.

Dark Picture

The procedure for correcting dark picture is EXTREMELY dangerous.. If you're not sure about what you're doing call a qualified technician or you could seriously hurt yourself or get killed!

Picture Dark, abnormal, Changing Color Temperature
  • Clean the Spark Gaps on each CRT PWB. Remove the Cap, clean the contacts with thin fine sand paper, blow out, reseal.
  • Remove the CRT Sockets, clean the pins on the CRT. Push the CRT socket on and off several times.
Make really sure before you sttart this process that the Tv has been unplugged for several hours and that you discharge the crt as you remove the anode. There is some extremely high voltage present for hours after the Tv has been off...
Or get a reputable shop to come out and do the procedure for you - - might just save picking yourself up of the opposite wall.

Dark , blurry picture

MTNESTR, My guess would be the FBT loc.TH01(flyback transformer) Hitachi p/n#BW03004 which would be far less expensive than replacing the entire deflection board... A shop could ring test the FBT to confirm the failure. I do know the FBT in this unit has an internal resistor that is prone to failure. It is in-line with the focus block and if it's open it would explain the blur and lack of screen voltage to light the crts properly. The deflection board is about $290-$350 plus shipping and a FBT is somewhere between $60 - $90 depending on the supplier. Hope this helps! Bill

Sony KP 53S65 53" rear projection TV contrast issue

While the root of the problem is likely the picture tubes aging, I'm sure it would benefit from a cleaning and adjusting. After the dust is cleaned from the lenses, the screen controls could likely be lowered to get the blacks you desire. An experienced tech would be able to do this for you.
