Interesting to use phone batteries for home automation. I own a 2013 Tesla Model S and have done repair of these packs with 7k 18650 cells. Let's just say water + electricity don't mix for a battery system that operates and may even live outside in humid/rainy weather. Anyway, you may find it interesting if your system have sufficient interior air volume that require air equalization (at least you won't have altitude change but will have temp change) Here is my post on post moisture failure of this battery pack.

Thanks for the prompt response and pointers.
Yes, returned the previous 2. Return shipping is on me
I'll ping DEJI although their online store ( [URL="https://www.dejibattery.shop/"]link[/URL] ) + website shows only mobile phone batteries and no laptops.
Ampsentrix cost is on par with cheapest stuff on ebay+amazon yet quality is excellent. I've used probably 20x now. Both complete batteries and cores requiring welding to the BMS. I guess they must have found the high quality supplier

Where do repair shops buy MB replacement batteries?
Order my parts from mobilesentrix.com and iPhone batteries have been excellent. Recently got 3x bad A1534 (2015) batteries. All would work until ~30-40+% and drop to < 10% instantly. Typical sign of cheap batteries.
Perhaps the less popular A1534 model's aftermarket batteries are more source limited. Just find it surprising quality from mobilesentrix (usually fairly high quality aftermarket parts) have been so poor.
BTW, this isn't the only defective parts I've had from mobilesentrix. Amongst others including iPad Air touch screen and A1989 touch bar (display was...

MBP A1989 Touch Bar sometime sluggish touch response
Had flickering touch bar display. Replaced. Now have an intermittent touch reponsiveness. It generally works but sometimes a press would not respond and need to touch again... sometimes more than 1-2x. Generally happens when trying to go faster on the touch bar and seem more common in certain regions on the bar.
Closer inspection reveal L5100 (touch sensor power rail coil) had overheated in the past. Perhaps it can't supply voltage or current properly. Don't have component available so thinking just replace with 0.1mm wire. Touchbar works now but touchbar just have some sluggishness...Last edited by howardc64; 07-24-2024, 01:44 PM.

Owner said LCD is good but why they take all the boards? I have same guess as you LCD is probably rubbish so don't want to pay high $ for board set. Thanks again for confirmation it will work and I'll decide if want to gamble haha....

Thanks. Just to confirm, you have 2 different model TV (GU-75TU6979 and GU-75TU7979) with identical LCD panel and different boards?
In my case, panel between CA02 and FA01 differ by 1 letter. Main t-con output connector circuit looks identical. Maybe likely interchangeable but thought I confirm before gambling on the replacement board purchase....

Unknown. Got TV with all the boards removed by prior owner. Need to decide to purchase board sets (expensive) to attempt repair. Samsung TVs with same PN often have different version #. Found a FA01 version board set much cheaper than CA02 version (the TV I have is CA02) which is why I asked if anyone nows FA01 main board (t-con on board) is compatible with CA02 version panel. Panel #s are 1 letter different. Info all on original post....Last edited by howardc64; 01-01-2024, 01:42 PM.

UN75RU800DFXZA FA01 CA02 Compatibility
Got a CA02 version without all the boards. LCD panel not cracked but unknown condition. Backlight seems to work with LED tester.
Board sets cost 2/3 price of the TV. Found a FA01 version board set for good price. ShopJimmy doesn't show FA01 CA02 as interchangeable. main board numbers between 2 versions are different but t-con to panel connection appears identical. LCD panel PN is 1 letter different.

Re: Toshiba 55C350 How to Remove LCD?
Indeed, for pros, time to remove double sided tape is prohibitive.
Its key to cut foam tape without making a bunch of debris. xacto and razor blade made foam debris that dumps between diffuser and LCD glass. What is your trick? cutter wheels?...

Re: Toshiba 55C350 How to Remove LCD?
[B]UPDATE
[/B]
Almost successful in repair. Unfortunately cracked the LCD nearly the last step trying to remove debris from underside of the LCD.
[B]Debris on underside of LCD Glass
[/B]
To remove the double sided tape from the underside of LCD require exposing the underside to open air for extended period of time. Only way to see and clean all dust/debris particles is with LCD installed (but not double sided sticked down) and backlight on. The natural instinct is to tilt up the LCD while installed...Last edited by howardc64; 11-04-2023, 05:00 PM.

Re: UN55KU6270FXZA Backlight Flashing Briefly on Power On
My notes said 2 dead LED post LED bar extraction testing with LED tester. Unfortunately forgot to correlate if on the string that ramped up slower.
Kind of a PITA problem to diagnose as backlight doesn't clearly show error while installed which is why so many people use the PWM_BLU disconnect trick. But this trick probably also runs the backlight brighter....

Re: Hisense main board surrogate evaluation
hi yes, I also researched this option but I did find a RSAG7.820.8831 at reasonable cost so chose that.
I vaguely remember the few pair of pixel signal wires are on different lines on the tcon-LCD connector so at a minimum, these would need to be physically cut and rerouted. The smart TV os is different as well (Andriod vs Roku) so I think chance of working is quite low.
I recall TVpartstoday had a board available every few weeks when I was looking but it will sell very quickly. So I registered my email on availability...

Re: Sony XBR-65X750D Horizontal lines bottom of screen
One thing positive about these XBRs is they are incredible thin (females seems to fans haha) and surely edge lit which provides a very even backlight. The cheap HiSense and TCLs I've worked on try to go thin with stuck on reflector paper with standard backlight bars. Almost never go back on with even backlight... probably wasn't that even coming out of the factory haha.Last edited by howardc64; 10-13-2023, 12:44 PM.

Re: Sony XBR-65X750D Horizontal lines bottom of screen
UPDATE : Blocking off VGH VHG_ODD VGH_EVEN AND CLK4 fixed the picture completely I figure line 13 was CLK4 (line 16 to 13 is 4)
I could remove the resistor/fuses on the buffer board for these (VGH need to be cut) but probably no difference from masking off the t-con output?Last edited by howardc64; 10-13-2023, 11:28 AM.

Re: Sony XBR-65X750D Horizontal lines bottom of screen
Nearly fixed by blocking out VGH VGH_ODD VGH_EVEN from T-Con on the failed side of the panel. Now picture is great and just have 1 bright line (13 from top) and line 1-12 seems dimmer/discolored.
Note the TV is upside down in pic below.
Possible to do better than this? Maybe the panel fault is line 13 and VGH* so have to sacrifice one or the other? LCD panel is LG.

Re: Toshiba 55C350 How to Remove LCD?
Thanks. Chatted with AliExpress vendor (I think same/similar seller on ebay shipping from China) selling 3 meter x 4mm VHB 5952 tape. They said they are authorized distributor and cut when order is placed. Reviews seems to be good so I'll see about giving this a try... IF I can get the old tape off the LCD haha...
Will report back after success OR failure haha....

Re: Toshiba 55C350 How to Remove LCD?
Looking for double sided tape to glue the LCD back onto the frame. My understanding is 3M VHB is best but 1/4" (6mm+) width is smallest 3M makes.
Original double sided foam tape (cut to remove LCD to change backlight) is 4mm wide, ~1mm thick.
Consulted with 3M chat support, they say its common for some distributor cut/slit/convert the tape into smaller widths. But need to be done in controlled environment / tools to not contaminate and lose stickiness.
4mm wide 3M VHB tape available on aliexpress but...
