I found a board in my collection from a 4 series, 421 I believe, that has all of the same connectors except for the power button. If it hooks up right, is there a way to turn it on without the button? Is it safe to even try this board? I'll post pictures of it later.Comment

Before you try a new main board with different set go into the service menu on the original TV check what the panel code is because you would likely have to change the panel code or else you're going to get a jumbled screen. Google how to go to the service menu and then find where it shows the panel code should be a number between 0 and 100 roughly so if you do try a different board that fits you will probably have to change the panel codeLast edited by EazyBone; 04-11-2025, 09:32 AM.Comment

He likes to push your buttons because you react. And when he gets his buttons pushed he cries too. Pretty sure just best to ignore.
You can easily look up a boards model number plug it into shopjimmy or eBay and it'll tell you.
And if it's for TCL and screen is jumbled ... After you set to correct panel it goes normal so I don't know what you mean by that. I'm not even saying this is going to do anything.

I just want to see if the vertical band appears, but if the screen won't display right because of the size difference, I probably won't notice, right?
Edit: nevermind that, I see it's missing another connector for the LED inverter.Last edited by x_orange90_x; 04-11-2025, 04:48 PM.Comment

For what importance it has now i remember years ago i bought a big tv from LG, the defect was the same and it was installed right under an air conditioner, that the owner said it dripped sone condenser water on the tv, after many tests on the panel boards, i found the target, wiith a magnifier lens i found a single burnt trace on a cof tab, the one with the correspondence to the issue on all its working area.. and that's it..Comment

Edit: so I tried cleaning them with alcohol and they all cleaned up nicely. No physical damage that can be seen. I even checked for ground shorts on them and they all tested good. However, I still have the band 😔 what's really strange though is that if you look at the attached pictures, you cannot see it at all except for on the lightest shades of color. Like literally, it does not appear on any of the darker areas. But if the whole screen is white or another really light color you'll see it from top to bottom. If one of these caps were bad, wouldn't it be permanently visable on ALL colors?Last edited by x_orange90_x; 04-12-2025, 09:11 PM.Comment

Please, if you use a smart phone to make photos, i suggest you to install a separate app to make trimmed photos for email / web exchange with a maximum of around 2k x 2k px, like i suggest in my sticky post, in Android i.use "Camera flash" from expertisenetcoms that has also a particular "light booster" (more bright on low light), good for boards, besides this i need a larger area pictured of the board so i can understand the purpose of those caps, i suggest you to replace them all the oxydated ones, generally you get them on spare cracked lcd boards (i store a lot of them) the same size /.same color hue ones, color has relevance for capacity, the darker the more capable, the newer the more cap/size ratio..
PS: check them for capacity in circuit, compare between them, they must match each other, the cof tab must be checked on the green side, by flipping the board..Last edited by Davi.p; 04-13-2025, 12:36 AM.Comment

I tried. They cleaned up nicely too.. Didn't look blown, burnt, or anything like that. The band was still present tho. I checked them for ground shorts and they all tested good.Comment

by Daren87Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
by Ryan.manHello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
by alltvrepairsHi,
i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.
Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.
Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?
Appreciate your help....2 Photos -

by smic717394Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... - Loading...
