Re: Problem with Samsung LN32C450E1D
Ok, thanks for your help. I've 3.80 rather 13V and 7.72 rather 24V...So I think your right about CM808 and ICM801. For main cap, Ive 390Vdc.
Well, I go to buy new components, I would give you result later

Re: Problem with Samsung LN32C450E1D
ok, Is power board needs to be connected to main board to test it properly ?
I mean, if power board is alone, so no connection with main board and driver board, do we have 24Vdc and 13Vdc ?Leave a comment:

Re: Problem with Samsung LN32C450E1D
I found that capacitor, white one, under board I can read CM808. Well, seems to be ok, but I've nothing to measure a capacity.
which kind of measure must I do ?...Last edited by Karutcha; 10-29-2013, 04:45 PM.Leave a comment:

Re: Problem with Samsung LN32C450E1D
For Tom66
For CB802 = between pin 7 and 8 from chips ICB801S = 16.75Vd
For CM807 =measure across RM807 = 14.74Vdc
For both measures, I moved power board on my table, so test is same as test1.
For budm :
I checked your request. In fact I did a new measure and I've got same as before : B13V = 3.78Vdc, B5V = 1.66Vdc, AV = 5.30Vdc, PS_ON = 0.74Vdc
But I'm not able to find cap CM808 !!! do you have an idea where is it ?Last edited by Karutcha; 10-29-2013, 03:08 PM.Leave a comment:

Re: Problem with Samsung LN32C450E1D
Input power is 120Vac
For this measure, all boards are disconnected from power board B44, and[B] I've 390Vdc for CP801S[/B]. Configuration as Test1 (B13V = 3.78Vdc, B5V = 1.66Vdc, A5V = 5.30Vdc, PS_ON = 0.74Vdc )
With configuration as Test2 (power board with Main board) : [B]I've an up and down between 360Vdc - 390Vdc[/B] (I've PS_ON = 0Vdc, B13V up and down all the time (0.5 to around 6Vdc), A5V = 5.3Vdc, B5V up and down all the time ( 0.3 to 0.7Vdc))Re: Problem with Samsung LN32C450E1D

Re: Problem with Samsung LN32C450E1D
Power board : BN44-00338B
Main Board : BN96-16387A
I've a schematic for BN44-00338B, if you can help me to find section to test, I will do it.Last edited by Karutcha; 10-29-2013, 11:58 AM.Leave a comment:

Problem with Samsung LN32C450E1D
Hi,
Model LN32C450E1DXZC
Power led is solid and on. Using remote control or switch give nothing. No sound, no blink from led, no power on screen. Fuse is Ok on power supply board.
Fuse RB803 = 1.02 Ω and RB805 = 10 Ω so It's ok too
TEST 1 :
I disconnected main board (CN201) from power supply (CN802), I disconnected cable from Power supply (CN803) to Driver board.
I measured with a digital meter and i get :
B13V = 3.78Vdc, B5V = 1.66Vdc, AV = 5.30Vdc, PS_ON = 0.74Vdc
TEST 2 :
No... -
