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.

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.

I'm trying to find a sweep board for s phillips 60' tv 1999 model

you have to get the actual part # from the board itself. Really the only way to get the part you'll need. Also make sure that it matches your tv model.

Mitshubishi VS-6041 No picture, sound ok

It has been my experience with that model mitsubishi that the usual culprit is loss of vertical sweep. If the beams in the picture tubes stops moving up and down this is detected by the micro processor and the video is blanked, but the set is not shut down. The usual cause of loss of vertical sweep is bad solder connections on the deflection yokes or a failed vertical output IC.

Vertical picture problems on my 1993 mitsubishi vs-50va2

Can you provide a more detailed description of the vertical problem you are seeing? There are a number of defective parts that can cause different symptoms. Few vertical problems are adjustments. Most are either poor solder connections or defective parts. The parts cost should be minimal.

Please confirm you model number here and try to provide more details on the problem.

Thanks,
Dan

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.

TV vertical height-Mitsubishi Model CS 35505

If the height has dropped down, you need to first find out why. Most likely there is a bad capacitor in the sweep power supply or the vertical output section. Good Luck

"Vertical Collapse?" means one bright hor.line in the middle of screen. this problem can be solved 1 check vertical yoke connector or wire loose 2 check supply to vertical section which normally comes from EHT transformer check components in vertical section or print loose regards thanks

Picture has horiz. lines

There is no vertical hold in the tv circuits now adays. You may find a vertical center or a vertical height. Your problem sounds like (if it has PIP Thats Picture in Picture) its in the PIP module and its a small module that stands up and most models of Mistubishi this module is no longer availabvle. The problem with the module is the small pana caps are leaking and ruins the PC traces. I have heard that theres a kit available on E-Bay to jump out this module. Now if its not the PIP model then it could be a few capacitors in the vertical sweep circuit. Also the B+ feed off the Flyback that supplies voltage to the vertical output IC could have a bad or leaky capacitor in the circuit. If your not a tech or solid state troubleshooter theres not much you can do and SHOULD take this set in to a repair center. Good Luck
