Re: Samsung LE37A336 TCON fuse keeps blowing
OK thanks. I understand.
let's check the fuse and U202.
I'll let you know....Leave a comment:

Re: Samsung LE37A336 TCON fuse keeps blowing
Hi everyone, I also have the same problem described in the first post. Is the T-com card the one located high above the PSU?
Thank you

Re: Telefunken TE32182B29C10
Thanks for all of your help.
I decided to change the mainboard. Now the TV works fine.
Thanks again.

OK thanks.
you made me understand.
CPU is U14. right?...Last edited by Bobo360; 05-08-2019, 03:24 PM.Leave a comment:

Re: Telefunken TE32182B29C10
MT5820LUNU,
Pin 120, 121 are connected to GND.
I guess it's not normal.
What are you saying?...Leave a comment:

Re: Telefunken TE32182B29C10
Without U49 I no longer have the 5V_CC short circuit.
someone yes, between the right and the left.
Yes, without U49 I have the two pins 2 and 4 towards GND....Leave a comment:

Re: Telefunken TE32182B29C10
Thanks for your suggestions. I just removed U49 and the short circuit between 5vcc and gnd is gone. But the pins of U49, 2 and 4 are always in Gnd. What do I do? Ps: I hope to remember where the capacitors were placed. Ps2: so I found that U49 was broken since now 5vcc is not at Gnd?Leave a comment:

Re: Telefunken TE32182B29C10
Then,
I told the diode D172, which was in short circuit (marked in yellow).
D172 removed from the PCB results in an open circuit.
I think something broke or happened in that area.
However here points are still in short circuit.
I took away all of them capacitors marked in red. But still in those garments there is a short circuit towards GND.
short circuits are also short circuits even the small capacitors marked a light blue dot. I would like to remove them, but I know that it is better...Leave a comment:

Re: Telefunken TE32182B29C10
Excuse me, my connector is Like the CN5 with 12 pins in total. And I have 3 pins at 12volt stby.
Pin10, 11,12.Leave a comment:

Re: Telefunken TE32182B29C10
I fed the card into the CN5 / CN30 connector with only 12V
Pin11 and Pin2 (GND)
I performed the measurements in the go points:
[B]
TP1= 1,2V
TP2= 4.31V
TP3= 4.24V (5V_STBY)
TP4= 221mV (3V3_STBY) I think it's normal, U1 is missing
TP10= 0.690V (1V1_MT5135)
TP12= 5.84V (12V_VCC)
TP13= 3.48V (5V_VCC)
TP15= 2.59V (3V3_ACC)
TP18= 1.52V (1V5_VCC)
TP21= 1.19V (1V2_ACC)
TP25= 0V
TP29=3.45V
TPT222=3V[/B]
At first glance we see that 12vcc is not...Last edited by Bobo360; 05-02-2019, 05:55 AM.Leave a comment:

[COLOR="Red"][SIZE="5"]I want to write to you because I solved the problem.[/SIZE][/COLOR]
I changed then:
CX822, CX819, CX817, CX826, CX834, CX835, CX823, CX824, CX812, CX811, CX841, CX825, CX812, CX820, CX837
and also the big CS813.
Some are small and non-electrolytic.
I changed them in steps, not all together, to see how it went.
So I decided to go a little bit upstream of the circuit and install a resistance and see the absorption.

Re: Telefunken TE32182B29C10
Hello,
I did some tests.
The D5 marked me as a fault, because I had a continuity in it, you have your clothes.
On the other hand it was not like this.
I disconnected both the resistance marked in orange and the condenser marked in Yellow. I have removed U1, but I have broken it off. (TL431SAMF2).
Returning to the D5 because it seemed to be short-circuited.
I noticed that you have leaders of the yellow capacitor, the tester shows me about 1.5 ohms, that is a very low resistance. it sounded...Leave a comment:

I don't want to feed, because it stinks from the motherboard.

Re: Telefunken TE32182B29C10
the zener diode D2 looks good. mounted measure 0.500 mV (multimeter)
What can I do?Leave a comment:

Re: Telefunken TE32182B29C10
Unfortunately I can't verify this.
Why.
Since I found the short circuit between 12V and + 5_STBY, by mistake.
Now if with the two cards connected and food.
I smell stinks from the main. 17MB82-2.
What can I check here?Leave a comment:

Re: Telefunken TE32182B29C10
Thanks for the reply,
the Q106 is not mounted.
So I broke something in the main?Leave a comment:
