Re: ECU's, interfaces and baud rates
Pentium
Thanks for your prompt reply.
It is looks to me that the interface works only with older version of Rhino view, which could have some parameters mistake.
Please correct me if I am wrong....

Re: Samsung FP-T5084 - Solved one problem, now have another (Clicking, Blinking LED)
Hi Tom
The circuit was covered with another layer (same as the underneath tape).
The origin shunt is SL432 which cannot find on local shop, hacked by a KA431Leave a comment:

Re: Samsung FP-T5084 - Solved one problem, now have another (Clicking, Blinking LED)
As wrote above, the power board has low standby voltage (3.3V instead of 5.2V), some thing goes wrong on flyback circuit, it control by an SL432 shunt reference ()
Cannot find replace part on local shop, I decided to create a flyback circuit myself with more popular shunt KA431, it look stupid:
But, voilà, work like a charm:
Finally, I get it up and running, save hundreds buckLeave a comment:

Found out that the Standby should be 5.2V as printed on the board:
Tried many things in standby area: replace standby rectifier, replace OPTO, replace all capacitors... still no luck, the STBY voltage stuck at 3.3V
Is there any idea?...Leave a comment:

In addtional, this TV is 2007 series, it should be older than T5084 one.Last edited by Viking; 12-18-2012, 12:54 PM.Leave a comment:

Yes, I have checked with all connector are disconnected, only AC inLeave a comment:

Dear Tom
I re_open this thread as my Samsung PS50P91FH (Same configuration as FP-T5084, same power board, just different in INPUT ports) have same problem. It cannot turn on, no standby LED, no blue light, just silence as it dead.
Eye check, all caps are OK.
As I think some thing is wrong with standby circuit (which use a DM0565R), I have changed 2 x 2200uf, 10V. Still silence
I measure the voltage of standby (Pin 3-GND_STB and pin 4-STBY on CN801 on above...Leave a comment:
