SOURCE: CRT TV vert section

Hi,

Vertical linearity is more of a DCV bias issue rather than feedback or AC coupling. Hence it would be more apt to suspect resistors rather than capacitors. Of course, it is also possible that the large IC that drives the Vertical output maybe at fault (least likely) but often would have trimpots for adjustment. Most current designs do away with trimpots and rely on self correcting (feedback loop) which is simply a resistor in the 100k range. In certain instances, it could be a thermistor or resistor or diode limiter attached to the yoke itself.

Best would be to use a service manual or at the very least a schematic diagram with voltage readings and compare actual on PCB against schematic.

If you could post back the make & model or preferably the chassis number of the TV, might be able to comment back known common vertical issues.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: Red, green and blue colours diveded on my TV

ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

SOURCE: colour problems on TV

HELLO
I think what you have here is a degaussing problem causing purity errors on colours. When you switch your TV on there is a coil around the rear of the tube which is connected to a posistor and this is to get rid of any residual magnetism.
It sounds like the circuit is not working correctly possibly caused by a faulty posistor. Another reason could be that you may be using the set by putting it in standby all the time - the degauss does not work as it should by doing this - the best way is to switch it off properly after use and on again by the switch on the TV itself.
If the problem does not go away, then you'll have to get a service engineer to sort it.
I wish you well with your problem (:-)

Hello
Check your remote control hanset for proper functioning. Get into this link to know more about the faults and repair to remote contorls.
http://www.fixya.com/support/r10192276-cleaning_remote_control_handsets

If remote control functions proeerly, the front panesl switches to be suspected. If any one mong the microswitches inside got strucked, all functions will be distrubed. it will be best to follow any more after replacing these microswitches. These switches can be located just behind the control panel of the tv, soldered diretly to a printed circuit board. You have to replace all of the at the same time. Just undolder one amoung them as as sample, when you go to buy for a new one.
If this also does not help you, repalce its memory IC. This IC can be located very near to the main system control IC, will have 8 solder terminals. A very small IC and wont cost more. Eventhough it is very small, function of it when the set works is great. Replace it. When you buy this IC, make a keen look on it number. It is very important when replacing this IC. All these components stated above, can be bought from most of the electronic spare part selling shops st your town. OK.

Hello
Its front panel microswitches are struk. These can be replaced. They are microswitches, which can be resoldered out from the front panel board. For this, you have to open your TV, take out the front panel after unscrewing it from the cabin, desolder one out of it and go with that microswitch as sample. You can bought it from electronic spare part shops at your town. Buy all of them and replace all at same time. This will solve your TVs problem. OK.

Cable on TV suddenly went to black & white (and a bit fuzzy)(some channels show faint colour). Was fine, nothing was changed, one day was suddenly B&W. TV screen is not the problem, all other cable...


Was playing around with the TV's menu and changed the Tuning Band from "HRC cable" to "IRC cable". Suddenly I have colour again. No one had adjusted any of the controls, so still not sure why one day it was fine and the next day it had gone to black and white, but changing the Tuning Band fixed the colour problem for me.
