As far as I know by my experience, this IC should work properly without any problem for a long time. If picture and audio is there, you should check the emission of electron guns of the CRT. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

SOURCE: Bad color .

Turn the set on without an antenna, so there is only snow on the screen. Measure the 3 cathode voltages at the CRT, red green and blue. If the 3 voltages are about the same, around 175 volts, then the CRT is bad (purple picture means bad green gun). If the red and blue are around 175 and the green is over 200 volts, then there is a chassis problem, usually the video output transistor itself has gone bad or come loose.

SOURCE: Sony KV-32XBR45 Problem

Hello Speakout,
You do not need that board. You can resolve this problem by adjusting White-Balance. (greenish picture tone)
I think you have enough technical knowledge how to adjust white balance of this TV.

Bright lines in the center of the screen the height is insufficient.replacing Vertical ic La7830,and 3 or 4 condenser no good.Need schematic diagram try to search for the jungle output.tnx more power


This is the vertical deflection IC of a CRT color TV. If you think it is fried then replace it yourself. For a datasheet of this part check the following link:

http://www.rdd-tech.com/product/la7830

If the problem is the jungle output IC cxa2159s could be a problem and not start the power supply. This can cause an error code to know for sure.

Our tv keeps changing colours to blue red and green


Your television have color problem.That symptom is cause of loose connection or cold solder in chroma section and color output driver transistor of CRT board of your television.You can fix that problem by resoldering the chroma section and crt socket section of your TV.first thing to do is open or remove the back cover of your TV,then you can see the crt board connected to picture tube.Resolder that parts,specially the color output transistor the red,green and blue driver.Resolder also the chroma section.You can see the jungle ic,thats the color ic.Make sure that there's no short circuit when soldering the PCB board.After the resoldering turn on the TV and check if color is normal.Thanks..

Our tv gets red lines across the screen before the picture goes out. Happens intermittently.


Sad to say, this is one of the symptoms of a picture tube that is on its way out. There isn't anything that can be done to repair a bad picture tube, and it's uneconomical to replace one. Keep using the TV, and when the problem becomes permanent, replace it.

Zenith television no color except when in the menue screens


The onscreen menu does not rely on the color circuit to produce a color menu.
The most common issues with that symptom are bad color crystal on the main board or a shorted transistor on the main board next to the video jungle IC

If you turn the color all the way off the picture should have good black and white if not the crt is at fault. If it is good it could be the jungle ic or the possibly the red color driver in the crt board

Zenith 25" Color TV - Model A25A23W


Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck Please dont forget to rate this thread.

Zenith 25in. System 3 TV. Intermittent problem with color going all red??


It certainly sounds like a drive problem in the set. It could be a bad connection on the CRT socket, a componet on the CRT driver board, a bad drive transistor, a connection between the CRT driver board and the RGB /video jungle IC, or the RGB/video jungle IC itself. If you know how to solder and or have some sort of solid state repair experience, you should be able to find this problem by simply probing around with a wooden or plastic tool tilll the problem arises. If you have no experience, there is no easy quick fix. You should find a local repair person to assist you with this repair. good luck PS Please dont forget to rate this thread.

Color


It needs repaired. I can think of many different possibilities causing the problem: 1. Shorted video luminance driver transistor. Should be under $200 total repair if you take set in. 2. Shorted green kine bias transistor. $200 3. Failed jungle ic. $250 4. Shorted green gun in the picture tube. More than you paid for tv set... Rca picture tubes commonly run 25% more than the tv set did new!!!!!!!
