Samsung LE37S62B TV: Power Supply and Inverter Issues, LED Blinks 4 Times

Hello.
Samsung TV - when the power button is pressed, the matrix will flash for a fraction of a second along with the noise in the speakers, after which the stand-by LED will blink 4 times. The TV was dismantled, all electrolytes replaced on the secondary side of the power supply (they were swollen), which gave no change.
24V power supply reaches the inverter, but I noticed that when the TV is "switched on", when unplugging and fastening the plug from the power supply to the inverter, there appears a backlight and porridge for screens for a fraction of a second, along with quite a large lye on the plug.
A friend from whom I got the TV said that before he died completely, the picture disappeared and the sound was still there.
I am asking for help in fixing the fault.
In the attachment I add a website.
greetings

Connect, for example, a DVD with a euro-euro cable and check if there is a voice, if there is a voice, look for damage in the inverter. Flashing LED Samsung TV means nothing, in this type of TV the LED always blinks during startup.

The power supply probably has a BN44-0157A check the voltage reaching the inverter is 24V
and what you have on BL / ON is the voltage that turns on the backlight.

Hello. Thanks for the answers. I have no way of connecting anything other than a VGA cable that does not send sound anyway.
Mr. Zbyszek, this is exactly the model of the power supply. The inverter goes with 24V power supply, and the BL / ON pin reaches 5.2V. Voltages already checked on the inverter connector itself.

Well, in my opinion, skip the disc for now because if it is 24V and 5V on BL / ON then
matrix backlight should be lit.
If you can't see from the front, look from the back.
Is that so ?.

The backlight is visible both from the front and the back and appears only for a split second after switching on the TV with the power button.
In the meantime, only the STANDBY LED will flash 4 times and the LED will turn off completely as if the TV was working, but nothing is displayed and there is no backlight.

Leave the discs as I wrote later, you have to have the matrix illuminated all the time without any blinking.
The reason is in the inverter or fluorescent lamps. The inverter works so that if there is something wrong with it, it is supposed to turn off.

I connected the image to the TV, which gave "noise on the screen" and after lighting in the matrix it was visible that the matrix works.
So the Inverter ...
The inverter is V183 XXXA - it looks like after a moment some Protect started to work.
I checked the operation of all fluorescent lamps by switching on the TV and unplugging the next ones - all of them are lit, only the upper one looks a little weaker.
How to at least find the section where the damage is, since the inverter turns off in a split second?

If you gently strip the matrices and remove the glass so as not to damage it and not tear the ribbons from the glass, you would get into the fluorescent lamps and you would know almost 100% what is the cause.

Enter all inscriptions from the inverter.

If you have fluorescent sockets on the cables, try swapping places.

I was hoping to change the plugs of the fluorescent lamps in places, but the cable protrudes by 1 cm and swapping the plugs without total demolition is not an option.
Other inverter designations: 4h.v1838.491 / b1 and CPT 370WA03S
At the weekend I should find a little more time to pull the matrix out.
I checked the Darfons resistance before, which is in the range of 5.2kohm - 5.35kohm on the plugs for fluorescent lamps

If the reason is in the inverter then you could buy e.g. the item but this reason is not necessarily in it.

And if you highlight the matrix from the back without a signal, press the menu on the remote control
it should be visible.

After replacing 2 fluorescent lamps that were dimmer, the same was still going on, with the difference that the power supply works quietly without squeaking.
The middle tapping of the darfons comes for the first 2 upper 0.2v, and for the other 0.7-0.8v. How to locate the inverter fault?
Unless there is a problem in the signal that turns on the inverter?

Try to swap fluorescent lamps first and measure if these measurements will be the same.

Measured mate hits the inverter especially secondary winding?

You have 2 white smd fuses on the inverter, check them, because one will be burnt.
