    Grundig GUD300HD Set top box. No signal!

    Hi Folks.
    Have a brand new never used "Grundig GUD300HD" and keeps displaying a flashing "no signal" warning. When the aerial is unplugged it stops flashing but warning remains steady. Auto tune picks up and stores the stations but still says no signal and "no information" when channel is selected.
    Have scart, hd and antenna all connected. any ideas where to check would be appreciated.
    I get reception on other units.Click image for larger version Name: P1120025.jpg Views: 1 Size: 931.3 KB ID: 2164574

              Have you tried updating the firmware over the RS232 port?

                      Bush eled32240fhdcntd3d - no aerial signal
                      by Phil289
                      Hi
                      Could somebody guide me as to what to check next?
                      This tv has slowly become harder and harder to pick up a signal from the aerial.
                      Sometimes if i leave it on long enough it will find all the channels and work great until the next cold boot.
                      Ive tryed another tv in the same aerial socket and it works fine.
                      Ive tryed the ‘faulty' tv in another working aerial socket and it doesn't find any channels at all.
                      There's no looseness to the aerial socket on the tv and checking inside on the power board and mainboard there's nothing obvious to see - its all...

                      Elitebooks (820, 840 etc. all gens) and those continuously flashing Power LED + flashing CapsLock LED
                      by STKR123
                      As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
                      I wonder if re-flashing the BIOS might be of any use here.

                      As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.

                      There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

                      Requesting Help For GA-970A-DS3 rev. 1.0, No Post code, no RSMRST# signal
                      by AstutePauciloquent
                      Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

                      I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

                      Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel

                      Failure Symptom



                      No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

                      Where is the short?

                      Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



                      Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

                      Good morning.

                      I have posted here before and have gotten AMAZING advise (thank you!). I'm back for more. This BCaps Sub Forum is so well attended I thought I would post here.
