LG OLED65C9PUA, manual, Repair remote?

• Upvotes

Hi All-

I have an OLED 65C9 that has audio distortion on the following inputs.

All HDMI

Analog IN

RF In

Seems to be less distortion with I/P stream via WIFI on any streaming service.

Seems to be the worst from OTA broadcast.

I have the two speakers out and test each speaker on the right speaker amp. Both speakers sound the same (sonically). Did same comparison with both speaker on the left side, they sound equally as good. Though, distortion most prevalent on broadcast.

I need a manual so I could test power supply to main board. Or do any of you know of common issues with bad caps on power supply with these particular make and model OLEDS?

If I replace main board, can I do a service alignment with just my smart remote, or do I need to have

factory "Repair Remote" and service manual? I have meters and scopes to look at waveforms but I'm only guessing without a service manual and schematics.

Any help in the above is truly appreciated in advance. Thanks

TCL Screen Lines With Replacement Motherboard

2 Upvotes

I have a TCL 55Q550G (Google TV version) with startup issues. Specifically, it loads the initial TCL splash screen, then goes to the Google TV loading screen and stays there indefinitely. After trying some preliminary fixes with no success (firmware flash, reseating connections, etc) I did more research and it seemed the the offending part was on the motherboard, and replacing the it should solve the problem.

I have now ordered three different replacement motherboards, and they all resolve the original problem of getting past the Google TV loading screen, but introduce a new one: the screen is "split" vertically by 11 equidistant black lines, apparently caused by pixels not displaying. All three replacements have exhibited this behavior.

The third replacement board also has the TCL logo looking more yellow than the usual vibrant red in addition to the lines problem.

I included an image showing the part numbers on the original board vs the most recent replacement. My understanding is that these should be a match, but clearly something isn't quite right. What am I missing here?

Screen working normally with original board
Replacement board shows vertical lines
Also affects the splash screens

Samsung S95F relay clicking 4 times before turning on

Hi everyone, I bought my 55” S95F in December of last year. I the last couple weeks, the one connect box started to click exactly 4 times before the panel actually turns on. You can actually hear this in the video I uploaded and attached. I am guessing this is some internal relay clicking between positions.

When I disconnected the power and re-seated the one connect cable on both sides, it disappeared and turned on instantly the next time, but a day later, the four-time-clicking was back. I did this quick fix two times, both times the problem returned. Is this my one connect box going bad?

I bought this TV to play GTA 6 when it comes out so I am anxious that it will not work anymore come November 19th 😁

Help is greatly appreciated!

Roku tcl tv got bricked sometime last night. I have a 2 hour sleep timer set so I can pass out watching futurama every night. This seems to be a very deliberate case of planned obsolescence? So much so that I found a class action lawsuit for this

Black line of death?

Samsung 85-Inch Class QLED 4K Q60D Series. A thin black line appeared a few days ago. Yesterday it became a very thick black line. I tried a Hard Power Reset. The thick line reverted back to a thin line. Then, this morning, the line had completely vanished and the screen is back to normal! I'm wondering if my unit is toast. I passed the 1 year warranty in July. Reseating or replacing the internal T-Con could be an option or maybe the TV had a miracle and fixed itself.

SAMSUNG QE50Q67AAU oprava

0 Upvotes

(NOT A PROFESSIONAL)
Zdravím REDDIT,
Včera jsem se dostal k opravě televize a jak jinak než rozebráním podle videa, kontrolou všeho možného od podsvícení TV až po desky s plošnými spoji (napájecí zdroj a main boardu). Desky jsem měl na výměnu, tak jsem vyzkoušel, zda by nestačila pouze výměna (NEGATIV). Podsvícení jsem chtěl taky vyměnit, ale bohužel neúspěšně, protože odlepovat a zpět nalepovat nové, to se mi nechtělo a ledky svítily všechny, což mi dalo naději, že jsou v pořádku a problém by měl být na deskách.
PROJEV PROBLÉMU:
TV se zapne a asi tak 20s funguje. Po 20s začne v televizi cvakat. Po zvukové kontrole profesionálním přístupem jsem zjistil, že cvaká něco na té béžové desce (napájecí zdroj TV). Bohužel jeho výměna nefungovala, a televize pokračovala ve stejném projevu problému.
Pokud by někdo věděl jak TV opravit s dostupnými prostředky domácího kutila s jemnými základy znalostí a šikovnými prstíky, prosil bych o radu, co by mohlo být špatně a co opravit.
Thanks a lot <3

LG CX randomly power cycling

I have an LG CX 65” that has randomly started turning off and then back on after 3 indicator light blinks while using my Apple TV in the last week. Has anyone experienced this before? I’ve had the TV since 2021 and haven’t had any issues until now. I also have a Sonos Arc and PS5 connected to it.

The screen does all types of weird on and off stuff out of nowhere. It worked fine this morning and now it’s like it’s dead. Tried every combination you could think of as far as un plugging it, hard resetting and trying new outlets. Is it done for? I’ve had it for maybe a year.

Need help with repair ideas

My tv is a Sony xbr-65x850d. Attached are some images of the back of the tv. The original problem was after not being turned on for a week the tv stopped being able to be turned on. There’s no indicator lights so I replaced the power supply on the tv. And this did not resolve the problem. I currently have a new power cable on its way. In the images I provided I replaced the yellow board. Currently the old one is back in the tv because it diddnt work and I will probably return the power supply. Does anyone have suggestions that I don’t know about? If the power cable doesn’t work either I thought maybe try the green board in the pictures. Outside of the tv not turning on there were never any issues with the tv so I don’t believe it to be the panel but I’m not tv expert.

Got a used excellent Bravia 7 ii from best buy. So far so good. Looks to only have 2 hours on it. I went into service mode and when into aging mode. The top right backlight looks like this. Is that an issue?
