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:

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.

Horizontal line running through the middle tv screen, no picture but has sound. TV is a Toshiba.


You haven't vertical deflection.
The ff caused the problem.
1. Dry joints on the vetical section.
2. Blew Vertical ouput IC
3. Open yoke vetical winding.
4. No vertical output from jungle IC.
5. Open supply for vetical ic due to open fusible resistor.

I've suspect that you have #1 and #2 fault. This is not Diy so I've advice you to send to repair shop or look for a qualified tech to isolate the problem.

Thanks for using fixya.

32 inch tv worked. after transport 8 hrs, there is no picture, just a flat horizontal line in center of screen. is this a bad picture tube? what else might it be?


Hi:
There could of been a connection in the vertical circuit that has come loose during transport, another thing is i hope did not use a dolly underneath to load and unload this unit as they tend to crack the main board in and around the deflection circuit. A straight line means there is no vertical deflection for the CRT, if you look inside the vertical output wires going to the yoke on the neck are usually yellow and white check this connector to see if it just poped loose while transporting.

Screen goes black but audio still works fine.


It sounds like the vertical output IC may have some solder issues. Often bad solder in the vertical circuit will cause the CRT'S ( Picture tubes) to shutdown for protection during loss of deflection and audio will continue to function. I would inspect the solder on the Vertical IC first.

Unit has sound, no vertical deflection. caps and output ic ok. have b+ to output. nothing at pin 2 of output ic.


If there's an audio,,it might be the defective Vertical IC...but check first if there's 24v-26vdc supply coming from FBT going to Vcc of Vertical IC.

If there's no Audio,and only white horizontal line in the screen,check the Vertical out of Jungle IC.

Good luck!

I HAVE GOOD AUDIO BUT A THIN LINE IN THE MIDDLE OF THE SCREEN THAT HAS VIDEO. ALSO THE SCREEN IS BLACK ON THE TOP AND BOTTOM WITH THE THIN LINE OF VIDEO IN THE MIDDLE.


Have you vertical deflection circuit checked for bad Vertical IC, and or Bad vertical Capacitors in the vert output section for the deflection board. Also have Vertical output Pump up Capacitor replaced, also have B+ voltage check coming from flyback transformer, for any open fusible resistors

Screen went black


Possible vertical output IC failure, which will cause the Picture tubes to shutdown but audio will still function. Try replaceing the vertical IC

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.
Please let me know if I can be of further assistance to you.
Good Luck!

vertical deflection problem. Vertical output IC, pump up cap, power to output problem, bad connections, jungle IC. Its a good idea to replace all electrolytic caps near the output IC. Bad caps cause it to run hot and self destruct.
