Question about Toshiba 32AF41 32" TV

Sound Ok, video OK; except viewing screen is like viewing through blue tinted glasses. When a 16:9 telecast is received, the rectangles at the top and bottom are blue like in the picture above instead of black.

Hi,

I don't have a projection TV as far as I know, but my knowledge is negligible compared to yours. Using the TV remote, I adjusted the color and tint. Now, the picture is not bad, but definitely not normal. I can see the NBC logo clearly, but the rectangles at the top and bottom when a 16:9 aspect ratio is telecast are still bluish black or what ever. I'm not familiar with the insides of a TV. Do you think the TV is worth fixing or should I just forget about it. I understand a new CRT would cost more than a new TV. Occasionaly, the power light flickers. I can correct it by unplugging the TV from the cable box and then plugging it back in. The TV is a monstrous tube TV eight years old. Originally, the tint was blue one time then yellow then back to blue again, That has not happened for several days. The front portion is over six inches deep and I can't see how it could be removed. Also, I don't see how the control panel could be removed. I don't trust Comcast, but they said it could still be the cable box even though a service man came not long ago, replaced the box and adjusted the color and tint. Many thanks for your interest and help.

Thanks and you do appear to be an expert. However, I don't think I have a projection TV. I think it is a conventional CRT tube TV that is huge - 188 lbs. It has a speaker on the left and another on the right. No part seems to be removable. I think it may be the CRT and if so it is not worth repairing. My basic question: Is it worth repairing by a reasonable repair person? Right now the picture is not bad, though it certainly is not normal. The colors of the NBC logo are clearly visible. Thanks for your help.

Thanks. I adjusted the Brightness all the way to the top, but it had little, if any, effect. David

Many thanks. I did a Google search on "white balance," but it only showed results for photography. However, the pictures shown looked exactly like my TV screen. I've made several calls and keep getting the same response: $100 to start with no idea what the maximum might be. Let's assume you are right. Can you give me a range or some idea how much it would cost to repair my TV and is it worth it. The set otherwise is excellent, but it is eight years old. There is one other minor problem. Occasionally, the power light goes on and of and the power goes off. This is easily corrected by unplugging the TV and then plugging it back in. For a few years I have had a strange problem that doesn't seem to have any effect on my TV. Every once in awhile (maybe once a day or every other day) I'm startled by a loud cracking sound. It only lasts for a fraction of a second. It may be a coincidence, but this started after Comcast installed a cable box a couple of years ago.

You have no idea how much I appreciate your answer and your time. I'm very grateful. Thank you very much. David

Many thanks. I'm afraid I didn't quite understand what you wrote; except to think you seemed to be a real expert. Please see Solution #2 and see if you were saying the same thing in more technical terms. Many thanks for your response and time. David

I don't know. I'm sorry to have bothered you. In your message, there were some things I disagreed with. I gave the model number 32AF41. The blue exists throughout, not just on the rectangles when there is 16:9 telecast. I just used that as an example. I'm sorry for all the messages, but I wanted to know about how much it would cost and I don't know if my TV is worth repairing. However, many thanks for your time and effort.

I am leaning more of a decoder issue rather then anything else on this particular problem. If this TV is analog witch I think is as I did not see a model number for it what has happened when in 16:9 aspect ratio the decoder is acting up decoder/tuner sorry there one of the same as they both handle signal.

1. check you connections
2. if this is a DVD, blue ray make sure you on the right correct resolution for this TV.

Other then those two issue's I would have it looked at if it is happening only in 16:9 witch is wide screen format usually dvd or High Def. Make sure your TV support high def as well.

I did not have the opportunity to read more of your comments to others until I fully commented the system does not allow me to see what others did with your issue, Further reading leads me to be-leave you TV will need repair specially the part when the Tv shuts off and you have to reset it in order to get it back on.

The $100 you pay is just a placeholder for the work done it has nothing to do with charging you more as if you brought it to my shop I would require the TV and some money to work on it now it if cost me more to do the repair of course you should be notified. I feel $100 would fix the issue and pay for the labor as a whole.

I see many people working on your solution but you questions keep getting answered with more ideas lets not throw parts at this thing and just get it fixed.

Of course you going to need to bring it into a shop no matter what we tell you since you did comment about you knowledge. The tuner board has all the contras and the convergence and what not on it, its all built in one logic board now this will need to be ran under some diagnostics to find out where the fault is but lets let your local tech handle that while you sit back and relax.

None of this stuff will make since to you if you no nothing about repair so to keep asking and asking and the buck being passed does not solve any issue at all it just makes other techs waste there time on answering the same question (not saying your bugging us at all) I feel you where given a wealth of information to take to the local technician and it will save you money in the long run.

Please ask the BBB Better Business Burro in your area witch is the best TV tech and take your TV to him/her You be glad you did.

Please do click the accept button to close this case as plenty worked on it verry hard including myself we typed allot and gave a wealth of information for the amount paid,

Thanks for using fixya.com

I would say it would be worht the $100 bucks total repair cost otu the door if it comes out to be more then yes a search for another TV will not be hard for what you pay to repair this unit.

Thanks for your many comments and I am sorry if I gave you any indication that you were bothering us. I just do not want another tech telling you something its not and that is where it seems to be going.

Have a happy holiday and may God bless you

=================================================

OK, if this TV is more then 4-5 years old then it requires white balance adjustment by tech.
Mean while, if you can do it easily, reduce G2 (screen) volts, G2 control knob is located on side of flyback transformer. Adjust it little bit to reduce G2 volts, do that if you are comfortable with it.
Thanks.

Hi

Thanks for using FixYa. The life of a projection TV is 10-12 years usually. And that of the bulb is 10000 hrs. However, the issue you are describing not tells you completely that it’s a Bad bulb. It can also happen due to faulty focus control or due to sparks on the fly back transformer. Also make sure to check the connections of the lamp, make sure the connections are firm.

Also check whether all the cables from your cable box are fine and connected firmly. If yes then you'll need to pull off the front of the TV, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. So, we are doing real small adjustments. Turn the color off on the TV and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittent blue lamp, a bad driver transistor a bad connection on the blue CRT board.

Replacing a lamp is a costly affair, so before replacing you'll need to check all other things.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

Rylee

Hi David

From the description you have
given in your issue it seems that the CRT has gone bad which costs around
$500-700 which indeed is more than the price of a new set. Unfortunately, the
best solution would be to invest in a new set. You’ll need to search the web
and compare prices and purchase a new set including an extended warranty and
get rid of the blues you’re facing right now with the eight years old set.

Please do accept the solution if
the issue is resolved or else revert for further assistance.

Thanks

Rylee

Picture has a yellow tint. It's from an old video game that ran over 12 hours a day. Has new bulb. Except for the yellow, works fine.

Hello there:
The best way to describe this is what is called screen burn in.
this is very common on screns that have games or pictures that arre displayed for long periods of time without being shut down just like on a computer screen when a screen saver is not used .
there is nothing wrong with the bulb.
the yellow that you are seeing is actually burned into the glass part of the projector and the lense
so if you can and feel like you can dissasemble the projector dissassemble it and locate the glass and see if you can get the yellow tint that will be on the glass and the lense off by using some rubbing alcohol and a cottomn swab
But if it wont come off you will have to replace the lense and the glass ok
Hope this is very helpful for you
Best regards Michael

Blue tint and lines on screen.

Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
