Re: Samsung LE32R88BD/ BN44-00155A
Hello. Please have a scheme to BN41-00813B? My TV still does not work properly. When cool the TV, the start takes a few minutes. I think that the main board defective (BN41-00813B). Can someone help me? Thank you.

Re: Samsung LE32R88BD/ BN44-00155A
So I can confirm today about my idea. The error will be outside the power board. Today I have another BN44-00155A. It's the same with her... I have 3 power board. 1.BN44-00155A 2.BN44-00157A 3.BN44-00155A. Put on card 1. (my old repair power board.) TV start after 5minutes. I will leave to play 5 minutes. Turn off the power cord. Quickly exchange it for a card 2. (157A). I turn on the TV and immediately plays. I will leave to play 5 minutes. Turn off the power cord. Quickly exchange it for a card3. ("new" 155A). I turn on the TV and immediately...Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
Today I tried to board BN44-00157A. I interject 12V and 13V. I made for the new connection cable between the power and the base plate. I hear the Power board starting pulse. So I connect the original connecting cable - TV starts immediately but only colored beads, and after a few seconds, turn off and on again with colorful beads. And so on. I give then again BN44-00155A. TV start after 5 minutes (today's heat abou 33°C, the greater the heat sooner TV starts ...) I leave the TV play about 30 minutes. Swap the power plate to BN44-00157A. TV and...Last edited by DaTT; 08-07-2015, 12:52 AM.Leave a comment:

Hello, I replaced all the electrolytes . On that particular part (number) should I look? Somehow rolled or ceramic capacitors ? Thank you. DaTT...Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
I managed to buy BN44-00157A that is on the Internet referred to as compatible with BN44-00155A. I joined her, and the TV comes on immediately after pressing the power button. Instead of the image appear as if analogue grain. And the TV after a few seconds switches to standby. So I looked carefully at the connectors. For BN155 connector CNW801 and at BN157 is CNM801. Furthermore, BN155 has written 5,4V and board BN157 has 5,3V ... CNW has 3x12V and 2x13V. CNM has 2x12V and 3x13V. And they are swapped. So just these pins (12V and 13V) to rewire...Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
Today I tried to measure the voltage is switched on TV and in STANDBY. So the supply voltage at ICP801S 15,3V (0V standby) on ICB801S 18,1V (20,9V standby) on CB806 20,8V (35,2V standby). If the TV starts (usually about 15 minutes) voltage fluctuates. ICP801S 0-15,1V. ICB801S 18,6-19,1V. CB806 21,7-32,1V. If the room temperature is higher TV starts faster. (28°C-10min). If it starts slowly lower (13°C-65min). Although I do not understand but I suspect that it will do component that cools when not working as it should. What should I focus on?...Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
Yes, I changed CP801 and CY801, CY802 (those two were the glue). When I press the Start button on the CP803 voltage pulses from 355 to 387VDC. After about 15 minutes tv starts, and then the voltage is 387VDC. So little time is decreased and increased volts on CP803. But TV is still unable to start immediately. DaTT....Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
Today I measured voltage. When connect only 230VAC, voltage on ICB801S is 10,7V and on ICP801S is 0V and on CP803 333V. When starting - on ICB pulse 18.6 to 19.1V and on ICP pulse 0 to 15,1V. After starting the TV - on ICB 19V and on ICP 15V and on CP803 387V. So the problem is in the ICP power? What I can also inspect? Please advice again. Thank you. DaTT....Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
I took CP803, so I looked at him. Something flew in it. As if he was inside another slightly smaller capacitor, so I changed it for sure. Voltage on it slowly rises up to 330VDC and the TV is turned on. (after about 17 minutes) So it's the same. Voltage on it by the label on the PCB should be 385V. Something prevents him ascend to this voltage. Where is the fault? Thank you for your time. DaTT....Last edited by DaTT; 07-08-2015, 09:35 AM.Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
Today I measured the voltage on the rectifier(BD801S). When I connect only lead AC230V, I can measure on it a constant DC327V. If I connect the other cables and I turn on the TV, the voltage start pulsate from 225 to 327V. Can anyone advise what to focus on? Thank you for the advice. DaTT.Leave a comment:

Re: Samsung LE32R88BD/ BN44-00155A
Hello, I have a problem with the TV. Does not turn on, the red LED flashes. The time at which switch on extended to several hours (even through 12h). Thanks to this forum, I went into repairs. After replacing seven large capacitors TV is turned on after about 17 minutes. By this time, the voltage varies from 2.5 to 24,6V measured at DZM854. and further 0.1 to 5,3V measured at DZM853. After about 17 minutes, the TV turns on but do not keep a few seconds after it turns over and goes. I also swapped CY803S, RM801, CM810, CY804S, RB801, RB806 (they...Leave a comment:
