Question about Mitsubishi CS-35505 35" TV

1 Answer

No vertical sweep

This was the closest match to my model which is actually a Mitsubishi CS35AX1, manufactured in 1993. I have no vertical sweep, just a horizontal line accross the center of the screen. For about 6 months before it died, I would occassionally have a few lines appear accross the top 5 inches of the screen which would shrink towards the top of the screen, and disappear completely after about five minutes. I live in the boonies and can find no one to come to the house to make the repair, and since this beast is upstairs, I figure I'll take a whack at it myself. I know little about TVs, but I'm an experienced HVAC tech and figure that if it's just a solder joint or component failure, I should be able to take care of it myself. I miss my TV. Can you please help?!!! Thanks. :-)

You might be able to take care of it yourself,you are corret when you said no vertical sweep,if you can identify the vertical IC it will be easy,you are looking for loose conections but by now it might have a bad vertical Ic and it needs to be replaced along with the safety resistor that power the IC,the ic should be mounted on a heat sink and the resistor should have low resistance,very straight forward repair and while you are there make sure and check for overheated areas and loose conections specially in the power supply , horizontal drive circuit and convergence IC's.Be careful you still have high voltage witch can be dangerous.

Horizontal sweep absent, is the fault. Vertical sweep is OK. Check for any loose solder terminals or loose connection at the connection goes to deflection yoke. Check all the capacitors related to horizontal scan output. google.com/+GopakumarGopalan

Mitsubishi cs-27tx1. Only has a thin horizontal line thru middle of screen


Hello

Total Vertical Sweep failure had occured in your TV. That is there is only horizontal sweep there, and the whole picture sweeps horizontally and you see a horizontal nice line across the screen, at the middle of it. In this case, all other buttons will work, and sound output will be Ok.

This fault is normally due to Vertical Sweep Out Ic trouble. You have to open the back cover of your TV, and have to pull the main board out. Locate the Vertical Output Ic. It is easy to locate it. There will be four wires going to the deflection yoke assembly [the coil fitted alongwith the picture tubes' neck]. Amoung them, two will be thick, and is carrying horizontal sweep signals. The other two wire are comming from vertical sweep section. Follow the wires and find out from where it comes from the main board. Somewhere near it orginates from the main board, you will see an Ic usually screwed into a heat sink [ a metal plate or so]; and it is vertical output Ic.

Check first, whether there is input voltage [working voltage] come to it or not. Sometimes an open resistor problem may occur to show this fault. Normally vertical section will have a voltage rating between 18 to 35VDC. If that voltage is there, surely the Ic said above is damaged. Screw it out and desolder it from the mainboard, and go for an identical type and number, replacing it will solve your problem.

Take all precautions when we works with an elctrical equipment. Keep away children and never allow even stand beside you while you are working, and let an adult beside you as a precaution. Never use metal chair. Do wear a plastic of rubber shoes. If can, keep matted the floor also with carpet. Ok
Wish you success.

Flatline!


the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high current.you need a special setup to discharge the picture tube.

Vertical bars and lines run up and down the screen. Need service manual or parts outlet


There is no such thing as a "vertical sweep circuit board" in that set. The vertical circuit is part of the sweep module. And BTW that type of symptom is more often a power supply filtering problem anyway.

No picture just line in middle of screen


Is the line across-vertical failure or up and down-horizontal failure.Don't have make/model of set.

Problem


Hello.
This indicates that your vertical sweep has failed and the auto protection circuit is shutting down the video so you do not permanently burn that line you see into the phosphor coating of the CRT.
At any rate, the vertical sweep circuits need repair before the unit will work again.
Good luck.

No picture


You have an intermittant vertical sweep circuit! It could be the vertical out put IC solder connections on the printed circuit board, or maybe the IC itself has poor connections between the IC and the contact legs that mount the IC, or another componet in the vertical sweep circuit. If you know how to solder and unsolder, work on printed circuit boards, then you shoul have no problem replacing the vertical sweep circuit. Good Luck
