Reduce the size of photos please..

by Davi.p

Hi all, i'm asking all to reduce photos to a more comfortable resolution before post, the better like around 2000x2000, otherwise many PC / Tablets / phones refuses often to load them or has strong defection... today's digital cameras integrated in phones especially are a mockery because them saves photos at enormous resolutions with much less the real definition, so reducing them is only a good deal.. THANKS!!...

Samsung QE50Q60TAU - Horizontal screen lines

by Runlinc

Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

I am left with a good image apart from the black horizontal lines that I cannot get rid of.

I cannot find anything on the buffer boards that has shorted.

Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

Many thanks for your assistance

Samsung LED UHD TV - Bad Main Board or Bad T-Con Board? Pictures inside

by E--Man

Hi All,

Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.

Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.

The lines are green in color when the tv is in "Game Mode" and...

Lenovo Ideapad 320-15ikb: Comes on and goes off

by Nagyesz

Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.

(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.

Any insights on what might be causing this?...
