Got this last week and finally got a picture, but it is not right. Bad screen or bad componet? See pic.

Re: Coby TFTV3227 weird line half screen fuzzy

Pretty sure this is the Coby unit that has a recall for being a massive fire hazard.Comment

Yours is a bit older, to me it looks like a panel/tab bond problem. Flex the tv see if it changes or take it apart and break it down to panel level And touch the tab bonds with something non conductive and see if it changes the picture.
Freeze spray works too.Comment

Re: Coby TFTV3227 weird line half screen fuzzy
After some studying, I just about have to think it is gate driver failure. I think this is one of the newer panels in which they are built into the panel. It is a Samsung panel with one ribbon going to t-con. What a shame. This TV is barely 2 years old. It's like we're living in "junk city" anymore.Comment

Re: Coby TFTV3227 weird line half screen fuzzy
Yes, looks like a panel failure to me. Too common on modern LCD TVs. If it's any consolation, you'd get the same fault if you had bought a Samsung...!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?
By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display... -
Hi folks,
This HP Pavilion Aero 13-be1021AU came to me for a repair. And it seems to have a weird BIOS chip. (Pic attached)
I asked my CH341A to read it and doesn't even know what to do with this. We are both very confused.
BIOS - XMC 25RU128CH10 (1.8v)
What the heck is this? I looked all over the MB. This is the only bios.
When I asked the NeoProgrammer to detect it, it just pops up an empty screen, and asked me to enter the bios number. And when I did, it doesn't do anything. NeoProgrammer showed me just this SPI ID: 204418. Don't know what... -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it... -
This started a few days ago and does this about every 8 hours
After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup
The battery backup is about 3 or 4 years old
Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start
