Re: Hisense 50P6
Thank you.
I cannot see any area around the edge boards or ribbons, indicating any dampness
The owner says she uses a dry lint free cleaning cloth on the screen only, as there are no children in their house
When you refer to BL, I am assuming that this is backlights
I am sure there is no problem with them, as when the panel is turned on, and is laying screen side down, I can see lots of bright lights via small holes in the panel area.
Does this indicate they are ok, or is the test needed?
Thank you.

Re: Hisense 50P6
Such a defect can be caused if liquid gets on the screen and gets on the decoder cables in this area where the strip was formed.Leave a comment:

Re: Hisense 50P6
disconnect the LVDS from T-CON side and turn on... if the BL come on then follow the test
- keep the LVDS disconnected from T-CON side.. make jumper wire between the power boards 12V line and feed it direct on F1 ( black fuse ) on the T-CON and turn on see how the screen look.
if the first point the BL didn't come on... but u still have the 12V on PWB ... do the point 2 but use torch light to discover what the screen displaying.Last edited by Diah; 03-08-2023, 04:46 AM.Leave a comment:

Re: Hisense 50P6
Thanks for the assistance.
TV brought to me today.
I undid and reconnected all the ribbon cables, no success.
In wiggling each cable from the mainboard, to the tcon, the two ribbons leading from the tcon, and as well as the edge boards, I noted nothing happening to the picture.
I turned it all off again, took a photo at start up again, as pictured (normal lines)
I then did as suggested,disconnected the power, removed one ribbon one side of the tcon, restarted, picture attached.
Powered down, reattached first ribbon and disconnected second ribbon, picture attached.
Put it all back to how it was, and lines still present in picture.
POWER BOARD ...RSAG7.820.7748/ROH
T-CON BOARD.....RSAG7.820.7931/ROH
MAIN BOARD......RSAG7.820.7970/ROH
Owner says tv has been good for 5 years, turned it on the other day, and all there was is the lines.
Your valued directions please, novice status.
Many thanksAttached FilesLeave a comment:

Re: Hisense 50P6
Can also try powering up with just one of those cables hooked up, check display, then do the other side, do all connect and disconnects with tv unplugged to insure against any errant surges or such.Leave a comment:

Re: Hisense 50P6
Inspect for damage and clean and re-seat same cables from t-con board to panel driver boards.Last edited by nomoresonys; 03-06-2023, 07:27 PM.Leave a comment:

Hi,
What would you look for first, to diagnose this fault please?
Many thanks.Attached Files -

Hello dear badcappers!
The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?
Backstory:
After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.
If there is a way to narrow down which memory module is faulty it would make my life much... -
HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when... -
this set delivered today to my home to inspect and write report to company sold this set 2 weeks before and the customer reject it as it had fault at picture. its look the transport damage happened during the customer sending it back to the company or on the way to me.. who care its not may fault. LOL

Hello everyone. 😀
As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.
Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
There are no devices that have exploded or otherwise show signs... -
Hey folks,
I'm not a professional, but I do have a decent amount of knowledge when it comes to electronic repairs.
A friend of mine recently bought a brand new Hisense 75” 4K QLED Smart TV (75E7NQTUK) but unfortunately, he cracked the screen just a few days later. Luckily, he had insurance and got a replacement right away but weirdly enough, the insurance company never asked for the broken unit back.
So, I took it off his hands and figured I'd try to repair it myself rather than see it go to waste. I've been searching for a replacement screen but can't...
