LE37M88BD Possibly Bad Lcd ?

[ReeceyBurger123]

Hello all deciding weather or not to buy this faulty Lcd Tv for £30 I have not yet seen it in person however the symptoms of failure are as follows:

Red tint to every image displayed.
Bar running across top of display.
Image is vertically separated by small black bars all 1cm apart.

What do you guys think this could be I am aware that this uses and Auo panel with As15 Ic which could cause the Red tint and small black bars. However the bar across the top could this be a Lcd driver pack failure ? Meaning this will need a new screen never seen and As15 fault cause this.

Let me know what you think cheers chaps.

The bar across the top looks like bad panel to me

Tbh looking at it I think its a mix of both, as only the red sub pixels are working that suggests As15 failure and I have seen an As15 cause the 1cm black bars across the screen as well. But the horizontal bar I think is Lcd failure either way dont think its worth the gamble.

If you sell parts it's worth a punt, if you don't I wudnt gamble on it, they suffer tab bond problems terribly

Yeah I repaired pne of these panels which if my notes are correct is a T370HW02 for tab bonds ages ago, however this looks more like a driver failure. Im buying it anyway just to see only paying £10 for it.

Nice, worth a punt at that for sure but I am a hoarder lol, I have a shed full of sets cheap/free that are for spares, mostly old obsolete stuff but handy sometimes

Got the tv here and as I predicted its a combination of failures. The As15-F Ic is failed, the Ic is burning hot and the gamma reference voltages are out some do fluctuate from 0-3v every so often which isnt good, As15 failed. Also if I flexed the Lcd the bar across the top would come and go however pressing on thhe tabs doesnt seem to solve it, so panel is also trash.

Im going to replace the failed As15-F which will be the fourth one I have done this week ! Then sell the Tcon which is fetching about £30-£50 on ebay. Panel and Tcon are Auo no wander they failed. Junk !

Thanks for reading.

AUO aren't too bad in my opinion.

They are ok have seen quite a few Auo Lcd glass fail. These panels which are also used in Le37R88bd which is the tv I have in my living room do have good image quality, color and contrast wise. Also seen the 42" version of this panel fail on an Lg as well.
