Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

White arcs across screen when the screen is dark or black.

I don't know when it started happening exactly but it is getting worse as time go's on. It is a series of arc going from left to right. They are stationary and a blue/white color. The TV is nearly seven years old so I hate to put a ton of money into it with the new technology out there. I really hate to put it down to, its been a good TV for us. Anyone know what might be going on? The calibration doesn't seem to help.

Replace a color gun in your KP51HW40. Then adjust the picture brightness to eliminate these rings by turning a little button behind the front (cloth like) panel (the one covering the front bottom half of the set). You may have to to dim the lights to be able to do that properly. The little dial button as is in the middle.

Projection TV no picture flashing horiz arcs across top of screen sound okay


You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

GFCI Breaker tripping when turned on


Try running the motor in the dark. You may find it arcs to the chassis of the motor and that is your culprit. Had same thing on a hot tub 10 years ago. The professional techs tried everything for me. i finished the last part at 10pm and turned the motor on and saw the arc then trip the gfci. Good luck

My Samsung HLN5065W started to freeze to a black and white


I have a problem with my HLN 5065W Samsung DLP that 3 other folks have and no solution. After the set is on from 5 minutes to 6 hours, the screen will freeze in black and white, I can turn it off for 5 minutes and it will display a good picture again. Sometimes the screen will just go dark blue, TV has to be cycled on/off to get the display back. This problem is getting worse, started as once a month, now 3-5 times a day. I have a tech background and can read a schematic, HELP.

These are called vertical retrace lines. They are going to get worse untill you find the bad capacitor(s) or replace the vertical driver/output IC. Please, if you have not the solid state repair experience, get a pro to assist you in this repair as there are no user replaceable parts inside this set. Good Luck PLease do not forget to rate this thread.
