Re: Philips 58PUS7505/12 Backlight OK / no picture.. Help
Had the same set about 3 weeks ago. The set was just above 2 years, same as yours.
Intermittent picture, sometimes it was ok, sometimes no vgl no vgh. Wrote it off as no fix, panel problem. There should be a manufacturing fault by the panel maker. Also seeing lots of 58 vestels with screen problems. I think it's the same manufacturer but can't recall correctly.

Re: About emmc replacement
Thanks a lot for the reply! I have already ordered KLM8G1WEMB but its gonna take a while to arrive and the client does not want to wait a lot. Lets hope it is new, I ordered a couple cpus and they were used. Will open a dispute soon. Is it safe to replace with another emmc, same capacity?

About emmc replacement
Hello. After lots and lots of tvs having firmware failure I decided to get a socket to reprogram the emmc. Yesterday I checked that one emmc had a 100% usage so it couldn't be reprogrammed and it should be replaced.
I checked in my store and I had no exact replacements for this emmc (KLM8G1WEMB-B031).
Is it possible to replace even if the part numbers do not match as long as the emmc has the same capacity?
Is there any anywhere where I can order new emmc. I checked few stores in Aliexpress but I think they are used or is it safe to order emmcs from...

Re: Samsung UE43RU7406 strange black figures
Post more pics from the menu. You should match the bn94 code. Matching BN41 code can work sometimes but its a hit or miss.

Re: Samsung UE43RU7406 strange black figures
I think its a software issue. Usually emmc goes faulty. Pretty sure a new mainboard would solve this problem.
Usually the menus are scrambled with big and assorted letters.

Re: KOGAN - KALED58RT9220SVA - Image flickering when in Energy Saving mode
If the picture dosen't show any artifacts like image jumping up down, or different colors. If it looks like only the background flickers then its probably dying leds. The video that you provided is very short but im kinda confident that its a dying led.

Re: Tcon fuses
In oldish lcd tvs it was quite common finding just the fuse faulty.
Nowdays on these newer sets I have never ever found a broken fuse.Most of the time no picture means dead panel.

Re: Un50mu6070 Mainboard issue
Original problem was 9v instead of 13v on the connector of mainboard. When disconnecting psu from mainboard the leds lit up. I posted my dump yesterday here [url]https://www.badcaps.net/forum/showpost.php?p=1206953&postcount=100[/url]
I kept the original untouched and I worked with spare dumps. With another 25Q40, on 2 times, I disconnected the cable between psu and mainboard, removed the 220v and then plugged back the cable between psu and mainboard and then put the 220v back on. 13V was stable, standby lit but it...

Re: Un50mu6070 Mainboard issue
I have 9v on the connector instead of 12v. Psu is tested ok. On one case the standy led lit red,(new 25q40 with another dump) in other cases there is no standby. Already replace 24c256 just to make sure. Should i give it a try to the emmc? I have a dump for this chassis....Last edited by ducky29; 02-09-2023, 11:26 AM.
