Question about Mitsubishi VS-4543 45" TV

Burnt out tube?

I just got this TV from a neighbor who moved out and he said the TV worked fine, but one of the tubes burnt out, it was either a blue or a green one, I don't remember what he said. He also said it caused the green and blue colors to not display properly. So I turned on the TV and it works, and there's also a quarter-sized blue dot in the middle of the screen. Not sure what that is either. Are either of this viable problems that can be fixed?

If you have a dot, this means that there is no scanning to that colour channel. This fault can be in the scan amplfiers or the deflection yoke itself. Another issue, is that it is also possible that the tube is weak. I am sure that the person you took the set from had an estimate done on it, and did not fix it for very obvious reasons.

This set will be very expensive to fix. Go out and treat yourself to a good LCD or Pasma set, and you will enjoy it much more than an old tube type projection TV set!

I have an old 36 inch widescreen Philips CRT TV which has been working fine for 7 years until yesterday when the whole screen just went blue with a series of white horizontal lines. The audio is still OK...


Hello
Since there is a blue screen atleast, I don't think that the picture tube is gone. The fault may be either to its chroma IC or video output section. In both sections fault cases, this type of horizontal lines [parellel to each other at about 1 inch or so apart the entire screen] will be seen. Just check the voltages at the three cathode, ie, red, blue and green of the piclture tube. This can be measured at the picrture tube neck card. If you have through knoledge in electronics, have patience and enough tools to do the work, inform me through Fixya. Without these, you can't work on a tv, especially in Philips.
Otherwise, get it checked by any expereinced service technician. OK.

Picture tube burnt staying at bangalore


You mean the picture tube screen burnt ? ! Then ---

Better exchange it for a value and get a new TV. There is no point in buying picture tube and it may be or may not be available.

There are plenty of multi brand shops in Banglore. You can get it exchanged! But one information. First find the the new TV price. ie market operating price. ( not the Maximum Retail Price )

After getting a price talk about the old defective TV. You may get a value Indian Rupeess.900(nine hundred)!!!!

LG CRT TV Problem


It sounds like your picture tube is either shorted at the blue gun or there is a blue drive problem. The blue driver transistor can short and cause the same problem. If it has little fine white lines as well, most likely it is the tube. Thanks for using fixya.

Picture is a blue screen but the cable and sound still works. The picture briefly appears when we turn on the tv then it fades to blue. Its a Prima tube tv.


It sounds like the picture tube is shorting at the blue gun. Most of the time it is not cost effective to replace the tube. Have a repair shop check it out and see if that is the problem. Thanks

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

My tv was dropped and now the color is messed up how can i fix it


Unfortunately, this can't be fixed without replacing the picture tube. The drop caused a piece called the shadow mask inside the tube to warp or break loose. When that happens, the red, green and blue beams in the tube don't hit the right places on the screen. There isn't any way to repair this kind of damage.

If you had professional movers doing the job, their insurance should cover some or all of the cost of repairing the TV (replacing the tube, that is) or replacing the set. I wish I could give you better news.

Seeing red !


I had a television that went to a bright shade of blue.A friends neighbor worked for sony television plant where the new tubes came down the assembly line.His job was to make sure tubes were working fine,if one color was dominant then his job was to smack the front center of the tube with a rubber mallot to fix the problem.He suggested i try that with my tube while the set was on.It worked and solved my blue problem.Apparently he explained,the gun connections in the tube came loose and to fix it was to smack it this caused the connection to reweld itself.For you I would use the palm of an open hand and smack the tube dead center with a good hard smack.Dont be afraid of breaking the glass because its very thick and strong.Give this a try.Hope it helps.Good luck!

FADING TO BLUE SCREEN


Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer
