What are signs of picture tube going?


Signs of a CRT going old, are bad focussing, unnatural colours and hues of a certain colour (red, green, or blue) if you watch black/white pictures. In colour pictures, black sequences also show hue.

No green and yellow colour


Hello
If you see the picture in yellow colour, means that there is no blue colour output from the video drive section in your tv, Yello is the mixtrure colour of red and green. Green is actualy there. blue colour is absent.
To detect this fault, you must open your tv. Just look in to the video output section, can be located at the picture tube base card, which is plughed into it diretly. See for any loose soldering points there. Check whether transisotors are used for red, green and blue output stages, or an Ic or three seperate Ics are used for this purpose. Anyway, blue catode of your picture tube pin gets a hig voltage, and so the blue emission is absent. You just check the voltages at red,gree and blue catodes, at the respective picture tube pins, which can be taken at picture tube base card. All of these three pin voltages must be somewhat equal to each other. In your case, no voltage at blue cathode will be higher that the other two. Check for the reason. It may be due to an open video output transistor [blue], or an Ic, of one Ic if used for the three colour outputs. Check and replace the same, will rectify your problem. Ok
If you have andy difficulty, get it to me through Fixya. Ok

I have Flat screen 14" monitor When I switch the power on the screen is blank but it changes through the four main colours and the Monitor power switch will not turn off . The Monitor is 5yrs old


It's not detecting the computer, Have you tried removing and reconnecting the vga cable usually has a blue tip on it with two screw looking apparatuses that twist.
try that first, second trouble is to check the video card.

Can't turn blue down, it overrides the other colours.


Conveergence is a huge problem here and if it overides the support your trying to give it it will be manually steered so it does not overide other colors.. You can do it carefully or can have a repair guy do it in about 30 mins or less good luck to you..

I have a 32" sonya tv about 10 years old.... Have no red color any more.. Where can I get this fix and would it just be cheaper to go get a new tv.


tv producess three colours red, blue and green, each of this has a different input on the tube (crt)
each has a seperate path from the IC to the tube neck.
on the tube are three transistors, each one for one colour,these transistor can be tested individualy,
if all this does not work, then take your tv for rejuvanation (opening of gates on the tube in puts)

Mitsubishi lamps


This set does have a lamp, it utilizes 3 picture tubes (red, green, blue) The tubes are not available as new any longer. It is recommended to replace all 3 after the reaches 5yrs of age because a new tube will over drive the others in brightness but it is possible to only replace the defective one. You can try Tritronics at 800-638-3328 for rebuilds.
