Replaced blown leds with some i had but seems not quite right.
Replacements were supposed to be:
3030 3v 1w
Vf 3.05-3.65v (250mA)
6000-6500K
120-130lm
but then chinese imports so who knows what they actually sent.
Think the colour temp is wrong, could see the difference before re-fitting but just wanted to see how it would look with panel back on. Not actually that noticeable whilst colours on the screen, its when its a greyish or white screen.
The black band across the top is of course where an led has gone out again, perhaps poor soldering, underated mA or just cheapo crud. Or could be another 'old' led gone out.
Funnily enough I ordered some of those earlier today, from a different supplier mind you and paid a slightly higher price for mine though, but will still have to wait around 4-6 wks delivery time.
Be interested to hear how they compare to your last attempt!
Mine arrived today but look very similar to the ones I have already replaced so think I will have the same problem.
Of course, I won't know for sure until I actually swap them over and power it up once its all put back together, not sure I'm prepared to go that far just yet!7
I have almost same problem but with 49pus6561/12.
Sound works, ambient lighting works, with flashlight I see picture.
So its backlight issue.
I measured +VLED to chasis GND and its 57v
When measuring -VLED to +VLED I see voltage between 8v - 60v. the voltage goes light up, down up down up down.
Even when backlight connector is removed. I also hear something clicking but cannot find or feel what it is.
Is this job for new PSU?
