Re: lg42PA4500
Blimey, new TV. 2012 series?
Looks like one of the panel voltages is a bit low, try it on some test patterns and see what they look like.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :

Hi,
Found an Funai 32FL553P/10 TV on sale for cheap listed as broken, so I decided to give a shot at reparing this.
State I got it in:
Squealing from the PSU
After logo I get a blank screen
After 10 seconds of having a blank display w/ backlight the TV dies
Give it 7-10ish seconds again and it starts to bootloop.
What I did so far:
Replaced all the caps on the PSU (apart from primaries, they were fine and none at hand)
Checked all voltage rails:
5VSB - 4.8V
AMP+13V - 14.4V
13V - 12.98V (in manual 12V)... -
I've got a Hanns.G Hi221 Monitor that works for a moment and then the display goes off but the power LED indicator remains on. If you power it off and back on again it does the same thing, it comes on and then the display goes blank. From a cold start it takes 10 seconds or so before the display goes blank but if you turn it off and then back on again after it already being on it goes blank a lot quicker so I'm assuming something is getting hot which is causing the display to go off.
I've uploaded a video of it happening on YouTube:
I've taken the monitor... -
Hi all, I’ve got a problem I hope someone can help me fixi.
I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...01-11-2025, 03:18 PM -
Hello,
I am having a problem with a ASUS VH238T.
The monitor started by just going blank, but the integrated speakers, and the backlight worked. The OSD didn't pop up, neither did the messages of DVI No Signal, nor the Asus logo.
Turning off the monitor, and turning it back on made no difference. But leaving the monitor off for a few hours returned the monitor back to normal. The problem will eventually return after a couple of hours.
Today, it started exhibiting another symptom: the display started showing a white image, that didn't take the whole screen....
