I posted a video on Youtube and a viewer had me check some voltages.  According to the datasheet A33VDD should be 3.3V but mine is 4.8V when I’m powering the system with 5V.

So I have ordered a replacment for U6 which is a TLV70033. Hopefully that will bring…Read more

I did try using a spudger to prod the components b…Read more

Too much voltage. When turning the switch half off, it showed brief signs of working correctly.

So I had an idea to lower the volatge on my bench PSU to 3V and it came on perfectly, but the little display wasn’t working properly.

Going to 4v and 4.5v and it’s working great.

What on earth is going on?

As soon as I moved it, the picture went corrupt again.

Somewhere there is a loose connection.

I’m still getting wrong colours. I’m at a loss as to what to try next.

I replaced the ITE IT6613E but that made no difference so I ordered a couple of TVP7002,

Just waiting for them to arrive so I can swap it over.

Hopefully that will fix it.

I have an OSSC 1.6 with corrupt graphics.

The fault is on both RG SCART and VGA inputs.
I have:

Updated the firmware from 0.82 to 0.83
Checked the HDMI out for loose pins
Check the ICs for loose pins
Reflowed IC TVP7002

Before I go further I thought I’d ask for some ideas here.

I have a video of the fault. This is a PC connected…Read more
