Re: Problem Source HKL-240101
Hello CapLeaker.
As you comment on the power on / off of the main board and the tests that I have carried out, I come to the conclusion that the Main Board would have to be changed.
In view of which I do not deserve to spend what is worth that plate and therefore
I leave this fault parked, until I find another waste TV that has the plate in good condition.
Greetings and thanks for your interest.

Re: Problem Source HKL-240101
Well I've already gotten the screen to turn on,
I changed the smd capacitor, C-6 that goes with a resistor
in series from 10k to leg 6 of the integrated circuit, U1.
Voltages in integrated circuit, U1
Pin 1.- 9.44v
Pin 2.- 7.13v
Pin 3.- -0.29v
Pin 4.- -0.21v
Pin 5.- 0v
Pin 6.- 1.09v
Pin 7.- 1.06v
Pin 8.- 4.31v
I only have to diagnose, because there is no tension On / off of the
main board to the PSU.
In attached files I accompany photos of the palace, in...Leave a comment:

Re: Problem Source HKL-240101
That's the first thing I did, all the electrolytic capacitors that the power source has
change them completely.
The behavior of the source seems like it wants to boot but it does not.
Would it be useful to change the optocoupler that it carries?
I've tried it and it's apparently fine and that's why I have not replaced it.

Re: Problem Source HKL-240101
Las resistencias estan bien colocadas, si te fijas en el video, una va a DIM y la otra
a On/off.
La Main Board no esta conectada a la fuente de poder.
No entiendo que quieres decir con "Did you check the caps yet?"Leave a comment:

Re: Problem Source HKL-240101
Hello Capleaker.
Back from my trip, I've done the test you tell me in the
post 8 (disconnecting the PSU from the source and putting the + 5v with two resistors in series of 1K with the pins DIM and On / Off). The result of the test is the one indicated in the attached file.
As you can see, the backlight LEDs turn off and on continuously and do not remain fixed.
Waiting for your opinion I greet you and thank you....Leave a comment:

Re: Problem Source HKL-240101
Thanks CapLeaker, today I go on a trip and I do not
I'll be back until March 5, when I do
I try what you tell me and I already told you.

Re: Problem Source HKL-240101
CapLeaker, what do you mean that a pin 2-3, which has + 5v with pins 5 and 7 through a resistance of 1K each and having disconnected the cable that goes to the main board, should turn on
the led strip ?.

Re: Problem Source HKL-240101
Hello Budm,
could you tell me what voltage should have pin 7 (BL-ON) and if that
Does the voltage come from the Main Board or from the power source?
And in the connector CN1 what voltage should there be to power the led
backlighting ?.
I do not have the plane of the source.

Re: Problem Source HKL-240101
CapLeaker, I send you a picture with the information
that you request, I hope it serves you.
The backlight LED strip is on the bottom of the
TV and is composed of 60 led, of which the source feeds
30 plus 30 in parallel.

Re: Problem Source HKL-240101
Hello CapLeaker:
Acontinuacion step to inform you of the tensions
that are measured, in the CN1 connector that goes to the backlight LEDs.
TV connected and blue led on with cable disconnected.- 11.21v
Connected TV and blue LED on with connected cable.- 11.21v.
In the CN902 connector that goes to the Main Board the voltages with
Connected cable are:
Pin 1.- +11.51 v
Pin 2-3.- +5.06 v
Pin 4-6.- GND
Pin 5.- +4.85 v
Pin 7.- 0.027 v

Problem Source HKL-240101
Hi all:
Again here to ask for new help.
The previous time I'm still waiting for power
get a T-con Runtk 5249TP, when you receive it
I will communicate results.
This time it's a problem on an I-Joy TV, with a
problem in the power supply HKL-240101 that in principle
did not light anything, I changed the resistance R-910 the R-907 the Mosfet Q901 (JCS7N65FB) and U901 (OB2273).
After these changes the power LED goes to blue level but
the voltage of the backlight LEDs is 12 volts only, so they do not light up. I try them with an outside... -

Thanks, I'm going to order the T-con, runtk 5264TP and when the

Re: Samsung TV with black screen
I read on the network that the Runtk 5246TP card gives less
problems that the Runtk 5351TP.Leave a comment:

Re: Samsung TV with black screen
Disconnecting the flat cable that goes to the
Main-boar, the voltages remain the same, absent.
I understand that it is necessary to change the T-con, I can replace it
for a Runtk 5246TP instead of the Runtk 5351TP.

Re: Samsung TV with black screen
Hello, indeed the fuse is bypassed because it was fused and as I said in my first post
I have 12.4 v. At the entrance and exit and in the points you mention I have no tension.

Samsung TV with black screen
Hello, good morning, I have a Samsung TV,
Model: UE32F5700AW, when I turn it on
it has sound and the led of the panel light up but the image
is absent, I have been told that it may be the
T-con. In the input and output of the fuse of this card I have
12 v., But I do not know where to measure more tensions in the T-con.
The code of the T-con is RUNTK 5351TP 0055FV ZZ.
Please can someone tell me the steps to follow for
find the problem
Greetings and thank you.
P.S. Sorry for my English. -
