Telefunken crt model Ttv280 Frame collapse how will i know if is the vertical ic or the jungle ic


Absence of Vertical scan output signal. You have to check its vertical scan output section circuit to detect and rectify this fault.
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Lg crt 29 inch tv wont start


The frame amplifier, like the line amplifier, will not work if there is no output from the oscillators for them to amplify.

Early 405 line sets didn't have a frame oscillator as they used the sine wave from the AC mains but I believe the later sets needed a frame oscillator and a sync signal from the rf demodulator to prevent instability.

Transistors rarely fail by themselves and it is often external factors that cause them to overheat and fail and an essential part of the repair process is discovering what factors caused the initial problem. Modern circuits use a lot of multi-transistor dc coupled stages and it is often the bias of an earlier stage that is the culprit.

The frame output transformer is usually very robust and much less likely to fail than a line output transformer. I suggest you ensure the correct operation of the oscillators before going any further.

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.

I have a 27" Toshiba television, I'm having problem with the sound. I've changed the sound output but nothing happen. Please help.


Hi
Jennifer Castillo


Here are some possible locations where to look to :
( Since I have no model for your TV or additional details which you have
replaced)

a) switching IC ( these IC switches the TV to Audio Video In)

b) muting circuits ( there could be one )

c) Check the audio out coming from the Jungle IC (also unknown)

d) check the supply lines of the audio IC (could be +12V, typical)

e) Check the headphones out (if available)


If there is an audio Out, connect an external amp to test.

If audio is present , check again for solder joints to main amp.


Use these as a guide in troubleshooting :

Computer Speakers

Your input is the Jungle IC, search on line for datasheet about it.

same with your Switching IC and Audio IC.


On some audio IC, volume control is included on it.

Let us know what you find or needs further assistance.

My Sony Model # KD-27FS170 have 4 blinking error code, I have change IC Part # STV 9325 did not solve the problem


After changing the frame output chip, have you got any power going to it? Is there any frame pulses getting to the input of the chip? and have you changed the dried up capacitors in the frame stage?
Is the scan coil lead connected properly, they can get dry joints and go open circuit.

Horizontal line and no picture


You have "frame collapse" as it is known. Almost always a replacement Frame Output IC will fix this problem after the leaking capacitors have been changed.
Hope that helps.

Doesn't always turn on stand by light is red and blinks 7 times thank you angie (tumbleweed64@comcast.net)


Flashing 7 times is a fault code usually suggesting a fault within the frame stage (frame collapse). This is sometimes just a poor soldered connection around the frame IC so would therefore just need re-soldering. If not most likely the frame IC would need to be replaced.
