SOURCE: tv cuts off 10 seconds after switch on and destroying vertical output ic

If the main IC is not putting out a vertical drive signal then the vertical output will not do anything and therefore will not be damaged. What exactly do you mean by the set "literally eats deflection IC's"? What is the number on the vertical output IC? I will bet that your pump-up cap or pump-up diode is defective.

Thanks for reply and nice to know that you are in Algeria.

You need to pay attention on Screen Volts as wrong G2 (screen volts) can be cause of 4 times blinks as you already replaced vertical out put IC.

You can download service manual of KV-HA21M80 from HERE and it is free. Download all 3 parts of file and use WinRaR to unzip it. You will have complete manual in pdf format.

Good luck.

SOURCE: Circle Vertical IC please on picture

I've cropped out most of the picture so it would fit here. The vertical output IC is I601. It's circled in the picture below:

If you can't place it from this part of your image, it's on the heatsink just above and to the left of the horizontal output transformer, which has the high-voltage lead running to the picture tube. Resolder the IC connections and that will probably take care of your trouble.

How to measure the voltage on TV


Voltage measured on DC scale, black cable multitester / avometer put on a negative path or can be slipped on the silver wire in the tube that is not disposable wrapping.

Next, measure the voltages are available:
  • For 180v voltage can be measured on the positive pin elco (10uf/250v) in PCB RGB tube.stick pin red wire multitester
d3f355a.jpg
  • Voltage 110v for TVs 14 "-21" and 130v for 25 "-29" in the B + FlyBack Transformer (FBT), find the path there is elco 100uf/160volt. measure on a positive foot elco.
  • For 12volt voltage, please measure at the foot of the right edge of IC 7812.
534aece.jpg
  1. For voltage 5V, please measure the right foot of IC 7805.
  2. For voltage 33v, please search at the foot of VT in tuner.
  3. To measure 90v-300v, scale use DCV 250.
  4. To measure the 12v-40v, use a scale of 50 DCV
  5. To measure the voltage of 1V-9v, 10 DCV-scale use.
  6. How to measure the voltage on the yoke and in plyback is;
    • From the yoke horizontal = Fcc 110v DC, 1000 V. AC voltage can be removed with a red plug in output and in use as dB meter.
    • From the yoke pertikal 24 DC current model, except for disposable coupling C = 1 / 2 Fcc. While it could be IC 120V AC (with dB meter)
    • At Fcc FBT kolector; 110v DC, AC voltage = 1000 V..
    • At Fcc FBT filement / heater = 5V-5, 5V AC.
    • In the FBT 20-32k anode voltage V measured with 40kv HV probe is added to the multitester 1000 V. DC.
    • Voltage others depending on model and type of TV. 180v out there (for RGB) directly from the regulators, transformers, Video Amp taken from FBT.
    • There are 24V and 46v vertical FBT, also 12-18V depending on brand and type.
    • Voltage 600 V DC and focus around the screen 400v DC.

    Thus tip n trick from me (AGUS YUSTIARA ), hopefully useful.

Picture when turned on, then image rolled up screen and went blank, but sound from cable box. did same when hooked up to antenna. now just blank


Hi,
Your vertical sync has gone bad. This is a very technical trouble on your unit.
The possible causes is the faulty ceramic capacitor on the jungle IC or the jungle IC itself.
Finding the faulty parts on that area required the diagram.
I've advice you to send your unit to your local Sony Service Center to fix the problem.
Also consider if your unit is still under warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.
Hope it may help you.
Have a nice day! JDVillanueva

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!

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.

As you say that it works for 5-10 minutes it clearly indicates that all parts are 100% ok. problem is loose contact mostly in power supply& IF IT IS OK then loose contact in horizontal section. Good luck.
