Your tv does not need an internal cleaning for brightness, I suspect that your tube has aged and either needs an adjustment or replacement.

Zenith SL2773W problem

The dark rectangle appears because you have the closed captions on and set to TEXT. Closed captions set to CC1 puts the words on the screen and TEXT puts a black box on the screen. Go into the menu, navigate to the page with closed captions and set your captions to OFF.

All works on tv but picture is very dark no matter what you do

if the brightness control has no effect, then picture tube is going out if it has a glass tube crt display. used to be a rejuvinator would cook off some of the deposit internally on the crt, but it also reduces the life of the set.

No picture, black screen

Not a TV Technician, use the following information at your own risk. Two things you can do first: using the keys on the front of your set press and hold the menu button when while holding it down it goes from menu to channel listing press the adjust (<->) and channel up buttons simultaneously to get to the factory set up screen once there use the select button to scroll to next set up screens locate the contrast it should range from 1-63 find the one you like. Second: for the horizontal lines not to say that this is the solution there are two adjustment apparatuses inside the TV chassis if your familiar with taking the set apart and not getting shocked and hurt59274cc.jpg two dials on the fly back transformer ones for focus the other brightness you can try these fixes but I have to say again that you use at your own risk. I do hope though that the information is useful

Blurred picture and it's also dark rear projection zenith Z52Z95D

I'd get the lamp replaced for sure. If it has a ballast - change that at the same time. However, a Zenith repair center should be able to tell you whether it's worth doing or not.

Picture is dark

sitnlisten - yes it does appear your pix tube is getting weak,but we may be able to turn up the flyback alittle to brighten up the picture.If you take the back off you will see the flyback-large black unit with a wire going to the round rubber cap on the back of the pix tube.Look at the flyback there are usually 2 adjusters one marked focus the other screen,just turn up the screen a little bit at a time.If you turn this up too much you will wind up with retrace lines on the screen.You may also want to check the pcboard ass'y for a sub bright adjust,and same thing small adjustments.If this don't help your pix tube may be too far gone.I hope this helps. cooltek Feb.1/08

Zenith rear projection TV

it's unual for all 3 crt's to go bad at same time, so have you tried turning up screen(G2) control? If so also there is a cap in the high voltage line that when replaced may lighten up set. Don't have model so I can't go further.

Tv still dim after adjusting

sounds like you may have gotten a pwer surge and blew out the regulator in the set. If you know how to trouble shoot regulator curcuitds then it could be as simple as the str type regulator. If you dont then open the set and see what module the set has it would start with a 9-something as it should be inside the back cover and then contact and see what they charge to repair the entire pcb or the exchange of the module. As Zenith sets are made to be repaired in house by quilifyed repair stations IN hOUSE. Good luck to ya.
