Question about Zenith B25A74R 25" TV

1 Answer

Color Problem I have a Zenith Z27H32D. Made in 1997. From my understanding, most tv's run on only three colors. Green, red, and blue. My problem is that I have green and red, but it appears that I no longer have blue. I still get a good picture, but everything is red and yellow. Is there a part I can get for this, or would I be better off just getting a new tv? Thanks

How can i connect a video camera to play through tv. my camera cables are red-white-and yellow. tv. is white-red- green-green-and red.


Your camera has three cables, red and white for stereo audio, and yellow for what is called composite video. Composite video puts the three color signals into one composite signal. Your TV sounds like it has a component video connection, which wants all three color video signals separated onto three plugs. They are usually color coded green, blue, red. Not sure if you mistook a blue outlet for green..... In any case, on my TV, it will allow me to connect a yellow composite signal to the green component jack, the first (leftmost) of the three component video jacks. Not sure if your TV will work this way, but it is worth a try. Otherwise, you can look up accessories for your video camera and see if it can output true component video and stereo audio, but I tend to doubt it will.

Change tv to another incomming broadcasting signal coaxal cable wire plug into it,might be lucky,the incomming signal wire is the problems.If it is not the incommming signal coaxal wire plug in.Than the tv RED color gun is dead,might have a dead CRT tube RED color gun.This problems is not easy to be fixed or determine.Should hire a tv tech to troubleshoot and rerpair.

My projection tv lost its blue tint


Hi

Thanks for using FixYa. Usually this happens when the Light Engine has gone bad, and I should say this is a common issue with Projection TVs. There are three tubes/mini LCDs inside your TV- green/yellow, blue and red. When the set heats up over time of usage the screens tend to break resulting in leaking color everywhere. The cost to get this fixed by a professional should be around $300 depending on the parts that needs to be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

Yellow haze


The blue filter is burnt out. A very common problem in Zenith DLPs. There are 3 color filters, 1 blue (a pinkish color), 1 green (a grayish brown) and 1 red (it is red) they give you your colors for you picture. This is a simple fix.

Blueand dark when picture should be yellow and gold bright


Well there are many causes for this. In the back of your tv there are three different color projectors. One red, one green, one blue. One or more of them seems to be out of alignment. They can be adjusted but it is recommended to be done by a professional as there are transformers in the back near that area that create the high voltage current needed to run the color guns.

Zenith A25A11D No Red Color


Hi, If you are comfortable working with a soldering iron, a continuity (VOM) multi tester and a fair knowledge of electronic components, then perhaps you can repair the missing color red. You have to open the unit, expose the small printed circuit board that is attached to the small end of the picture tube. There will be many components present but you will need to focus yourself on three (3) transistors that are bigger than the others sometimes with an aluminum heatsink. It is also possible that instead of 3 transistors you will have one power IC. In any case these control and provide the drive for the 3 colors of your picture tube: red, green and blue. One of them is either dead or suffers from cold solder to any or all of its pins/legs. You have to visually inspect the solder joints of these big transistors/IC and determine if any is dull in color, loose of simply not connected. You may even try the shotgun approach and solder each of the pins/terminals/legs just as long as you don't cross solder creating a short between pins/legs. If this works, you're set, if not: You have to check with the use of the VOM and determine which of the 3 transistor is defective. If you are familiar checking continuity of base to collector to emitter and reverse, again you're set, if not perhaps you check all three and compare which have the same reading from the same position and which is different. Pls keep in mind the transistors have forward and reverse bias readings. If able to determine defective component, desolder, replace and solder. If it were an IC, replace the entire pack. If the above would make you uncomfortable, pls ask for the services of a qualified TV repair man and explain your problem. Hope this works out for you and give you some ideas. Pls post again how things turn up, good luck and kind regards.
