Question about Sharp 55R-WP4H 55" Rear Projection Television

1 Answer

Adjusting visuals on the TV does nothing

My problem this time is that the TV seems very dark when watching something from an HD component. When I went to the menu to adjust the color and brightness, the TV didn't adjust to any different settings, I also tried changing the settings on non-HD components and they also did not recognize a change. Any ideas?

This problem may have been coming from the Flyback Transfromer or the Tippler, you have to be a technician to adjust that! if you are, well first thing is to put the TV ON and sent up all the level to max for the brightness & Contrast, then after try to adjust the Flyback screen voltage for hi bright, if it work there, try back now to see if you are getting any control of the menu of brightness & contrast to work! please be careful, there about 28K volts to 35K volts, this can kill anyone... IF YOU ARE NOT A TECHNICIAN PLEASE DO NOT OPEN THIS TV.... RandyXi CriticaL PaniX

Picture is pink in places and dark scenes the picture is mostly green


Oh dear.

It sounds like you have magnetised the screen by placing something magnetic too close.

Your only hope is to unplug the TV, and remove ANYTHING magnetic away from it, such as speakers etc. Give it a few hours then retry.
If this has been going on some time, it will already be too late.

The other possibility is the tube could be going!

Digital blocks appear


The HD-ILA's do not handle dark content well, it's a known problem. As far as intermittent digital blocks while viewing regular content it may be coming from your sat/cable company or you may have a problem with the digital board. I've had a few of these go bad.

Blotchy picture


I get this too with my Samsung. Are you watching HD content or standard (cable, satellite) tv? If it's the latter, that's why. The lack of quality really shows on analog signals. The shows that I Tivo look horrible a lot of times. Another thing is the connection to the television. If you are using standard RCA connectors, try switching to either component or HDMI.

Hope this helps.

Red-striped ghost images.


when you leave your TV (no matter what kind) and you leave it for long periods of time on a static image or something.. the image tends to burn in to the screen... so changing the glass would be a way to fix it.... the problem is that that kind of repairmen is more expensive and difficult than buying a new set...

Sanyo ds31590 picture's very dark and red


sounds to me that your picture tube needs rejuvenated.
You will need to get it done by a tech.
mechanical doesn't mean a thing when it comes to electronics.
Mechanics when working on electronics, end up costing more damage when you end up taking it to a tech.
