Re: Sharp LC-60LE847U
It was the panel. Aarrgh! One of the ribbons/chip must have gotten too hot was not touching the heat sink correctly..,the chip laminated to the ribbon was visibly different from the rest. Looked kinda like a blob. Oh well, now I have another set of boards..Has not been my week..first the Toshiba 4K panel, now this one! Out of all the sets I have bought, only four have had bad panels. Have to take the bad with the good.Comment

Re: Sharp LC-60LE847U
but hold it... are you talking about one of the side tabs or a bottom tab "ribbon". Does this set have "tabs" on both sides..... if it does, you can "disconnect" the bad side and still have the set work well.Comment

Re: Sharp LC-60LE847U
That sucks. Another note taken on Sharp LCD panels. I wonder if he disconnect the left hand drive ribbon cable from the t-con if that tcon no longer its hot and he said it before
This is known as vertical tab driver failure and is not repairable unfortunatelyDid I leave the soldering iron on?Comment

Re: Sharp LC-60LE847U
ya... I hadn't looked at the pictures "in big form" but was hoping... :-)
I am certainly glad that "my set" had issues with the side and not the bottom.Comment

Re: Sharp LC-60LE847U
Indeed, it was the far right bottom tab/ribbon. Alas, I now own a full set of boards for a Sharp LC60! YeeeHa! LOL
Added to the collection..PN59 Sammy, PN42 Sammy, KDL40 Sony, Toshiba 4K 58L series.
Complete sets.Comment

Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
Hello Sharp TV experts
Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.
> I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
> There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...01-24-2025, 11:51 PM -
Hi all,
this unit comes from a samsumg LCD TV LE32C530F1W which stopped working after making a strong noise like something was exploded inside of it.
I opened it and found that fuse FP801S was blown, capacitor CP814 was completely disintegrated and MOSFET QP801S was shorted.
I replaced all of them and instead of the fuse I connected a 100 Watt bulb. Then, without connecting it to other TV boards, I switched it on, but the bulb begun to blink.
I thought that maybe the bulb was somehow interfering with the normal operation of the power supply, so I replaced it with a fuse,... -

Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...
