Response to Stampydragon

Yes, I suppose static discharge could have caused the damage but the only time I have the Rpi connected to HDMI is for the initial setup and after that I run it remotely and headless via VNC. The problem appeared in August when humidity is usually 100%, temperatures are in the 90° F range, and cloth...

Response to most recent by timg236

Yes, I was using a freshly installed copy of the v. 4.19 (released 2019-09-26) iso,

Changing over_voltage=1 to over_voltage=4 and uncommenting out dtoverlay=vc4-fkms-v3d results in same screen problems (see below):

Response to hippy, etc.

Yes indeed, it worked well for several months. If I were a vendor, distributor, or manufacturer responsible for replacing a defective computer or computer component, I would strongly suspect user error in diagnosing the problem or user abuse of the part. The onus would be the on user to prove otherw...

Success, thank you timg236

Thank you timg236, implemented your suggestions sequentially and separately. Commenting out dtoverlay=vc4-fkms-v3d worked (see below)! I'd appreciate it if you would tell me what that did and what are the performance costs of doing it.

Thank you again for your help!

Thank you mikronauts, HawaiianPi, and Ernst!

Thank you all for the suggestions. I assume that when the vendor replaces a defective unit, it's returned to the manufacturer who reimburses the vendor but with Micro Center, there's also the distributor (Element 14 and Newark as I recall). I suspect that complicates things. It'd be great if Raspber...

Re: Recourse for probable defective unit

Ha. I like the art gallery option... can you suggest a buyer?

In answer to HawaiianPI: Yes, the same aberrations appear when connected to an HDMI monitor; it was just easier to do a screen grab from VNC than take a picture of the monitor.

Update

Thank you all for your responses! I doubt the HDMI cable could be the cause because the screen grab attached to my original post was running the Rpi headless via VNC with no HDMI cables attached. The problem is most obvious in the Chromium screen but is clearly evident elsewhere in the screen grab. ...

Recourse for probable defective unit

I'm a long-time and loyal Raspberry Pi user having owned every model ever issued but have never encountered a problem that I hadn't caused or that I couldn't solve. I now have one which I believe is hardware related with the display on my several-month-old Pi 4 2GB. Although the unit has worked with...

Re: SOLUTION: VNC does not start on a headless Raspberry pi.

Great, thank you! Given the number of folks running their Pi headless, shouldn't the Pi org make this install standard on the distro?

Re: Problem with startlxde and jessie

Thank you, startlxde-pi gets me further... the GUI comes up completely but crashes immediately when any action is attempted. The jessie GUI is attractive... but not sufficient to justify jumping from wheezy. OTOH, the ability to access the GPIO directly from Python (idle) is an excellent reason for ...

Problem with startlxde and jessie

I have used startlxde with putty and Xlaunch for years to work with my variety of Rpi. IMHO it is the most practical way to use the Rpi (particularly on mobile robots via wifi). I have had no problem with this arrangement using wheezy but haven’t be able to get it working with jessie ; it starts and...
