If it is CX3231 it is a ceramic disc capacitor 1000 picofarad, 2000V.

Evenly spaced vertical lines


Hello
Check the smoothing capacitor to video output supply voltage, usually derived from any one winding of the LOT. It will come around 10uF350VDC to 47uF 350VDC range. If this capacitor is faulty, or gone less in capacitance with time, this type of fault will occur. Check the green volour output transistor on the video output card, can be located attached to the neck of the picture tube; for any loose soldering or leakage. OK.

My picture tube displays all black except one thin horizontal line in the middle. There are no horizontal or vertical adjusts that I can fine. Is the picture tube burned out with just this one line?


Hello
A thin horizontal line across the screen denote that the vertical swep or output has damaged, or there are some loose solder points to vertical output section. Loose solder problems are very common to the vertical output sections of most of the picture tube based TVs. Just open your Tv, and pull out the main baord out of it, which has the vertical output section circuit. You must have some knoldge in electronics to proceed. Locate the vertical output section. usually, this section will be composed of an IC, which will be screwed on to a metal heatslink, to radiate heat out of it when it works. Check whether there is any loose solder terminals at this section, especially look for it at the solder terminals of IC and other components around it.
It is very difficult to detect the loose solder points, as some of them may be so microscopic to detect. Just do, what we do at service table, with this type of fault comes to us. Just resolder most of the suspected solder terminals by applying a little more solder without making any sokder bridge short between adjecent solder terminals.
If this does not help you, check the input voltage to the vertical IC. If found OK, replace the vertical output IC. If there is no voltage to this IC, check the track that brings voltage to that IC. Usually, this voltage will come from one amoung the terminals of LOT [Line Output Transformer]. Check the track, rectifier diode, limiting resistor etc. This is really a skilled work, and you should have all tools for an electronic work, and a skill to detect the faulty component. OK

JVC 27D201 picture gone except for one bright line across the middle, .5 cm. high


Hello
Vertical output section of your TV is faulty. There are mainly three resons for this fault. The first one is of faulty electrolytic capacitors at the vertical output section circuit. The second one is the vertical output IC. The third one is of loose solder termitals of components at the vertical output section. Resolder most of the solder terminals of this section by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. If this does not help you, replace all electrolytic capacitors at the vertical output section circuit of your TV. There will be 6 0r 7 of them the most. Replace all of the at the same time. They won't cost more. If this does not hlep you, replace the vertical output IC. OK.

Tv runs fine for 30-45 minutes then goes black except for bright horizontal line thru center of screen, volume stays on


This is a vertical problem. It may have a bad solder joint or it has a vertical IC or surrounding compoenents heating up and going bad, Try not to have the horizonal line on for to long, it can burn the screen if left on very long. If you have some electronic experience you could get some freeze spray and wait for the set to mess up and spray the freeze around the vertical section and locate the part that is heating up. Be careful because there is HIGH VOLTAGE is this area. Hope this is helpful.

Sharp 27G-S60 no vertical picture


your problem is due to vertical section failure.

 

 as you say it was intermittent for a while, but now is permanent

please check the followings as given

  • remember you should keep brightness as low as possible to avoid crt burn.
  • there might be loose contact in print or connector loose for deflection coil.
  • check supply to vertical output section
  • check components in vertical output section like electrolytic capacitors & low value resistirs.
  • check verical outout ic .
  • hope this will help
  • good luck.

Re: ask assistance


caution reduce brightness to protect crt burn. vertical line with sound ok is due to 1 deflection coil connector loose or wire going to horz.coil disconnected. 2 capacitor going to h/winding loose or defective. 3 print break from eht to h/coil.

Mitsubishis TV Problem


have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?" I would love to save the TV. Hi nothing to worry just minimise brightness to avoid screen burn. "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

Jvc model av36230


you know its in vertical section, try to look for a capacitor and changed it, this is more of a capacitor problem.

Picture is cut off on top and bottom


Thats is not going to fix your problem. You have a bad vertical output IC and or a bad capacitor in the vertical drive or output circuit. Good Luck

No picture on half of screen


The vertical output IC is most likely the cause. On a 27 inch TV the generic part number is AN5522 the location number ic IC561. Be careful of dangerous voltages within the TV powered on or off.
