Horizonal line across middle of screen top half of picture perfect bottom half has small lines in picture hitachi hd S 69 plasma


I'm not sure if this model is the one that has resistors that go bad. You can actually purchase a pack of resistors in a kit. It will come with solder, the resistors and instructions. You can lay the tv out and take the circuit board out to find the blown components, and replace the bad ones. Takes about an hour start to finish and will cost around $65.00. It has been a few years since I did this, so I'm not sure on the price.

I have a Vertical Line down my Tv? Its a Samsung LN46B550 Sound Works I can still see some of the picture... All HDMI Inputs work... HELP


So your HDMI inputs work fine without the vertical line?

If every input displays like this, there is a high chance that the problem is in the TV panel itself.

I had something similar with a Sony TV, except the lines were horizontal and the panel was replaced for free under warranty.

Slow picture and dark reddish tint


These sounds like you have an issue with main board or tcon. Picture slow makes me think this is a communication issue between the tcon and the main board.... This needs a professional diagnostic. The good news is i don't think it is the panel which would make the cost of repair beyond the cost of the tv. If it is in warranty or just out of warranty call sony, sometimes if it is just out of sony's 1 year warranty they will make exceptions. But you need to call them for this exception.
Some solutions are not cut and dried and an on-site diagnostic is best. In your case this is true. I have worked on sony for many years and that symptom (at least the way it is described) is not one I have seen.

No picture


just an idea the t.v. is 10 years old ok. Now look at the back can you see inside if so chances are there is a build up of dust which makes a great t.v. wrecker. So vacuum the dust out and see if that helps.

Toshiba 52HMX95 DLP has weird gray think line


DLP TVs work projecting light throught a tube covered with mirrors, called the light tunnel.

The gray shadow it is something in the middle of the light tunnel, probably a mirror that has gone out of place when you moved the TV.

Just a line on the screen?


Your tv has a failure in the vertical circuit. Most likley since you explained that it was coming in and out you could fix it by Resoldering the connections on the vertical output IC. Replacing the vertical output IC would be your next step after this.

The problem lies in you camera's CCD unit which is located on the back of the lens held on be 3 small screws it could also be a setting in the camera's menu try going into the menu and reseting the camera to default it works some times if that does not work than you need the ccd replaced pretty easy fix I fixed 1 with the same problem about two weeks ago for someone it happens I hope this helps you out.

The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.


You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
