After replacing the display driver IC TSUMO58CDT9 the problem still existed. Thought that it had some internal temp sensor that always shut it down...started up...shut down etc. Could not find any problem at all on any component...i thought :-).

After replacing the driver IC the problem was still present.

This is on driver board 715G7661-M0B-000-0H4K

As soon I blow some hot air on the circuit board (led driver ic )the monitor shut down. When the problem still was present even if...

Before they just flashed once and then turned of. I had a bulb in series with PSU and when I disconnected one of the backlight stripes (of two) the unit started. Then i could connect the other one and it still worked. But idf both connected then reboot. over current protection some how. BUT...when doing the procedure above and both were lit, the bulb gloved 20%. Some partial shortage....

I have fixed the problem...even if i exchanged both of these ic:s (yea...there were two identical circuits and both ic:S that had same outputs) ..one...

Re: Led driver TPV101AD Datasheet



mmm...had that one. Just need to know the expected values etc on each pin.

Thanx anyway....

I have tried to find the datasheet for this IC. It is a led driver ic.

on this power supply in my case. It is designed with two exactly the same IC driving one ledstripe each.

TPV 715G8620-P01-000-002S for Philips 43PUS6412

Located bottom right hand side.

Anyone with better friendship with Google than me? ;-)

Thanks in advance.
