It looks like the CRT tube on your TV came at the end of its days, if the tv is 15 years old or so this can be normal.
It may not be woth repairing.

    I dont think this has anything to do with the the jungle chip.
    In the best case it can be color amps ICs.

    The service manual is not available for free download.
    If you need the service manual you can buy it here

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.

In my tv is 10 years old and by the 2007 we replaced with new board(Only the CRT is the old one). Last day I was switched on my tv only sound only came and no picture. I can able to see the menu setting in...


Hello
Your TV is fitted with Toshiba kit I understands from your description. There is a sub-brightness contorl on board [a small preset resistor, which can be adjusted with a small screwdriver] fitted near to the LOT and towards its left side, on board. First try to advance the screen voltage by adjusting the screen control integrated with LOT. Screen control can be located at the bottom. If it does not help, adjust the sub-brighness control. If sub brighness preset is faulty, this kind of fault may also occur. So replace it with a new one. As far as on screen meny display and blue back screen at no signal is there and the sound is Ok, there is no other fault with the kit, other than adjustments. OK.

How do i get the screen to light up more, its to dim?


Depending on how old your computer is, your lamps may be failing,
Or you may have reduced the brightness, look for two F buttons generally F7 and F8 for screnn brighness, hold down Fn or function button and tap F8 to increase brightness.

Picture is very dim


there is a problem in the flyback section of the tv set. the fly back has two knobs, one for screen and the other for focus. use the screen knob to adjust the brighness. if it did not help, either check the capacitors around the flyback or change the fly back with a new one. good luck

Toshiba TV


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.

Screen too dark even with all brightness settings set to max


The picture is very dark it is mostly due to 1 power supply output is low. 2 voltage on crt g2 pin is low. 3 video output supply is low. 4 some components in luminance section might be defective or loose. 5 finally crt getting weak is set is old. good luck
