Hello, dear forum users! I have a Panasonic CF-20A0198VM. After the update, the laptop rebooted, the screen was black with no image. Disabling the BIOS battery did not help. I am attaching a BIOS backup. Thank you in advance for your help!

Re: Panasonic CF-20 no screen
Still relevant. I really need a working dump! Or information on how to collect a dump for flashing the programmer from the update from the support site. Also, it might be possible to check my dump and fix it...Comment

Re: Panasonic CF-20 no screen
Try this one.
CF-20A/B/C/D (mk1)
Bios updated to V1.00L27 ,ME firmware to 11.8.93.4323
If its working you might have to install the latest ME driver and EC firmware
ME Driver: https://pc-dl.panasonic.co.jp/dl/dow...4323_inf_2.exe
EC: https://pc-dl.panasonic.co.jp/dl/dow..._1_m195071.exe

Hello 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... -

Hello,
Stopped by this site trying to fix my parents Panasonic Plasma TV.
Model number is TH-50PZ85U
Power comes on and the red power light stays on solid.
Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.
I also hear a few clicks.
I also think my parents said there was a thunderstorm and the TV failed after that.
Section 6 in the service manual talks about power and no screen,...10-30-2024, 10:09 AM -
Hi,
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... -
My Panasonic Plasma model P55VT50 has started displaying "interference" on just the left half of the screen only (left when facing the screen). Sometimes it's concentrated in about the first 30 seconds after startup, then disappears. Other times it's fine at startup and then randomly does it later on. When it flashes the interference it's very quick and doesn't stay on the screen unless it flashes repeatedly in a row.
This image is a screen shot from a video I took. This is an example of the interference at its worst. Often the interference is much smaller...10-14-2022, 04:54 PM
