Question about Mitsubishi VS-4544 45" TV

Mitusbushi VS-4544 Horizontal lines then looses picture.

Hello All,

I have a Mitsubishi VS-4544 that recently started having some intermittent problems. The television picture is a good as it was when purchased new in 1996, however after some hours on we notice some horizonals lines across the screen. After a while the lines come more frequently then the picture goes out. I opened up the back cabinet, blew out the dust, and looked for any leaky capacitors. The only one that appears a little funky is c953. It doesnt appear like a regular capacitor. After reading around the net it suggests looking for cold solder joints around the power supply and points to resoldering the vertical IC chip. Does anyone have the part number and location of this IC? Any other suggestions? I am awaiting the download for the service manual, so I should have it shortly.

When the television plays, it works perfectly until the problem starts.

Thank you

    Does anyone have any schematics of this unit?
    I think that there are 3 flybacks for the 3 crts, would they all fail simultaneously?

I'll take a guess here that the lines are at a slight angle. I believe that these are "retrace" lines and are an indication that the flyback transformer is starting to fail. The vertical IC would cause a collapse of the picture and bad caps in the circuit would effect the linearity of the picture. You can check for poor solder joints as they could cause any nunber of symptoms.

Keep us posted.

How do I hook up a dvd player to vs 4544?


Its a old set but hookup should from a DVD player be to the rear audio and video inputs---note color of jacks on player--you will need for that old set composite--yellow(video and color), red and white for sound.

If the player does not have them (composite) you have a real problem.

Once connected use the input button on the front of the set to change to that input that you hooked the player up to (video 1 or 2 etc.)

Panasonic CT-32G6E Intermittent single horizontal line


I would suggest to locate a part that looks like the one on this link and re solder all the pins, also check for any high power resistor nearby the IC295890 and put some fresh solder.
Let me know if you need further assistance.

Horizontal blue line


The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

For some reason it started to take a longer time to warm up...


This model has several caps. on the power supply voltages such as the 5v, 9v and 12 v lines that begin to dry out and open and such problems begin to manifest themselves. Most likely this problem will continue to get worse and worse. As far as burned in images there is nothing that can be done short of replaceing all three picture tube and that is very expensive and this unit is to old to consider a 1000.00 repair.

Horizontal roll on mitusbishi 35" tv


is this a horizontal black line going up or down? if yes, this sympton is caused by a trouble in the integrated circuit or in the vertical oscillator circuit. this symptons has 2 variations. one is the intermittent rolling of the picture. this referred to as the "loose vertical hold" the other variations is the continuous upward or downward rolling of the picture

Black screen with green smiley face


If your tv has a picture tube,your problem is in it. If you have only one line now,the vertical circuit is not working. You could have jarred something loose around the picture tube.Maybe a yoke lead ???
