I have an old mitsubishi TV model cs 35203 serial 515512, and all that shows up on the screen is a thin horizontal line through the middle.


You either have a cold solder connection on the vertical output IC401 or a failure of the Vertical output IC altogether. The part number should be labeled clearly on the front of the chip and is likely LA7836 or LA7837. It's difficult to reference parts on a set this old. Remove the chassis and visibly inspect the solder connections. If they look good, replace the chip. Good luck

I have a Mitsubishi WD-62525. In general the picture is great from all sources (cable, component, and hdmi). However, there occasionally are very thin, horizontal lines that flicker across the screen....


I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

Black line across screen


module problem take it to a Authorized dealer or a NESDA dealer service manuals hard to say if available since analog TVs are slowly going away and parts well another story might as well go buy a new HDTV set as a CET no garuntee how long it will be analog TV parts will be discontinued. FCC has alot to do with it.

No Picture On Screen


it sounds to me like your tube has gone , go to your local tv repair shop and order a new tube its quite cheap to do so and they should be able to get it you quite fast.

Panasonic PT-47X54J Not working


I can't tell you how to fix this set, but I can tell you that its not a "lamp" issue as this doesn't have a lamp. Its a 3 picture tube projection TV. the three tubes are in a red green blue format, and average about $175 for each one, not including the labor to install them. your problem, may not be the tube, but just a power supply problem, but there is a chance it is.

Thin red horizontal lines across screen


replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

Mistubishi WD-52527 52" LCD Projection TV


those are going to be dust spots on the LCD panels internal to the optical engine. i suggest that you take the screen off and take off the panel i nthe middle of the tv with 2 screws in it and there will be an area that has 3 metal fins covering thin orange ribbon cables. the 3 square objects at the end of those ribbon cables will be the LCD panels spray wiht air compressor unitl clean and that should greatly help your problem.
