Magnavox 25inch TV picture problem

TV Picture is too long...distorted...can no longer read all of the ticker at the bottom of the TV Screen. Magnavox TP2590 B101. This symptom has occurred in the last couple of days. We purchased it new in circa 1991. mI think the set is getting ready to go bonkers.

That's a vertical deflection problem and is probably caused by a capacitor going bad in the vertical stages or the power supply stages that supply the vertical IC . And you're right, as the cap dries out more, it'll only get worse.

There is a company called PTS Electronics that rebuilds main boards and sells them on an exchange basis. You might check into that, but you really need to have a little knowledge about that stuff to install a main PCB.

You'll need the part number off the board.

Hope that helps...

Ticker along bottom of screen for news channels and sports channels is being cutoff along the bottom. That is, the ticker moves right to left and I can read it but the bottom 10-15% of the letters is...


Hi,

I might need a little more detail to solve this problem - I suspect the problem is an incorrect setting on your cable/satellite receiver (assuming you are using one), but let's start with the TV.

Firstly, switch the TV on and select a channel where you can see the ticker. Then press the "FORMAT" button (above the red REC/CONNECT button) on your Mitsubishi remote control. This will change the screen aspect ratio and the current setting will be displayed on screen. Each time you press the FORMAT button the screen size should change.

The screen aspect ratio settings for your TV are STANDARD, EXPAND, ZOOM, STRETCHED and NARROW. Press the FORMAT button repeatedly until "STANDARD" is displayed on the screen. If the ticker is still cut off, you need to change the aspect ratio setting on your cable/satellite receiver.

Please note: If the TV will only allow you to select STANDARD, this is not a fault. It simply means that the aspect ratio cannot be changed on the TV because it's displaying a picture from an external source, i.e. a cable/satellite receiver.

You should then look for a button on the front of your cable/satellite receiver or the cable/satellite remote control marked "FORMAT" or "ZOOM". When you have located this button, try pressing it repeatedly until the ticker is both fully on the TV screen and the picture covers the entire screen.

If you don't have a FORMAT or ZOOM button for your cable/satellite receiver or you are unable to set the picture size correctly, leave the TV set to STANDARD and then reply to me with the brand and model number of your cable/satellite receiver. I will then be able to assist you with finding the correct picture settings and give instructions on how to set these correctly.

I hope this helps - please post back here if you need further assistance.

Regards,
BElectric

Wavy horizonal disturbance in picture


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Just recently the image became distorted at the top and bottom of the screen, like an arch going up from the bottom and down from the top?


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu.

My rear projection 51mp392h has color distortion on the bottom third of the screen,it curves up in the middle. Is this a picture tube


Hello tj444,

This is not a picture tube problem. This could be what is called pincushion distortion. It is caused when the is a malfunction in the deflection coils and the inability to correct for the curvatures caused by the CRT. The pincushion distortion can also be caused by the degradation of the functionality of the convergence amplifiers in the TV set. I would suggest that you have a TV technician examine the deflection circuitry and the pincushion circuit, this would also include the convergence amplifiers.

I hope this helps,

Thank you,

Blurry Screen


The bottom is blurry because some of the anti-freeze (clear ethelyne glycol) has leaked out. This anit freeze needs to be replaced or the CRT will get too hot and break. It will also clear up the picture.
