HI,
i got this tv some time ago.
I saw 2 post regarding this power supply, but neither of them solved my probem
.
the Symptoms are:
When tv is on standby (red light steady on);
I press power button and it starts to blink red light 5 times;
Then enters on standby again without turning on.
Reading the posts found on this forum decided to "retouched " a bunch of solders, hoping that the problem was a dry solder joint - no luck.
Unfortunatly doing that QM801 got dead, RM813 blew up, DM804 open, DZM805 and DZM806 dead , and fuse blown off course.
Replaced all of them including QM802.
Now when i connect the tv the red light goes on. But when i press the power button i start to ear a noise, after two or three blinks of the red light. Somethink like when u connect a small call with wrong polatiry similar to a squeeze noise and decide to disconnect the unit from the mains.
As a last resource i removed CM809 and CM808 but ended up with a blown fuse.
ps: i have also removed all the glue from all the caps.
Could someone please help me?
thanks in advance.
