Re: Philips QFU Chassis "UpgradeAll.upg"-file
Thank you very much William! I can do some experiments with this file. You also have by accident the UpgradeAll.upg for the 1.2 chassis?

Re: Philips QFU1.1 Kernel Panic
I talked to Beeldbuisje on Circuitsonline.net and asked to check the reference voltages of 750mV for the DRAM's. He came to the conclusion that one of the resistor chips was broken. Replaced and tv was repaired.Leave a comment:

With booting until the "cannot mount VFS something block (249,0) the NAND Flash is just fine. It's often an DDR RAM VREF resistor at the bottom that's broken. (2x 1k in series with 100nF caps over it)
It should divide 1,5Volts to 750mVRef to define what level is logical "1" or "0" for the DRAMs.Leave a comment:

Did not reball the processor. Thinkt it's not possible that this is the main board...
The distortion is static, it does not move. Pressing the screen at the bottom doesn't change anything. Heating up the TCON same thing, no change. Looking into the close-ups, it's always even or uneven lines that are affected...
How probable is it that the panel is defective?Leave a comment:

Philips 55PFL7007H Vertical lines
Dear Repair friends, this is my first post from the small country Belgium...
I have a TV, a Philips 55PFL7007H/12 - QFU1.1E-LA Chassis
It has vertical lines in the image.
Some of the the lines are deviate very sharp, some have a mild brightness deviation.
I added pictures to clarify.
What i already did:
- Reseated and cleaned all flex connections
- Checked 12V power to the board = OK
- Reflowed the main BGA of the TCON Board
Possible causes of these defects:
- Panel defective (distortions also noticable at just over the...Last edited by Wiebotje; 02-07-2021, 08:04 AM. -
