rgh no hdmi output, possible image fault?

[vortex]

hello,
I bought a falcon recently that had a bunch of ripped pads and missing resistors from an RGH attempt. I fixed all the hardware and glitched it successfully and got the CPY/DVD key and lock down values.
The previous owner did not have the original nanddumps to give so I got help from a fellow on irc (thanks bl4k3y) who built me a glitch image with some info provided by me about the console (cpu/dvd key, region, drive type etc)...the xbox already had ECC written so it booted Xell.
I had the xbox near my computer at the time and used a vga AV cable and everything seemed to have worked fine (dashboard boots, dvd game plays), untill I moved it to my TV and used the HDMI cable where I couldn't get picture on the screen.
The console glitches and boots normal 5-7", circular rings and everything but no picture through HDMI, not even with Xell (eject), using an AV cable (vga at least) works.
Hdmi cable is not the problem, I've also tried resetting the display settings (Y+RT - xbox resets settings and reboots which is normal, but no image).
Any ideas what the problem could be ? Thanks

edit:
reading a little i understand it could be something wrong with the hana ? I underwent some serious work but everything was put together properly says my multimeter. Here are some photos ...

Disregard that, I failed to spot the 0402.

Hey guys,
I've ran into exactly same issue...
I have a Panasonic Viera, tried every suggested solution but to no avail.
No signal on HDMI, AV works great...

Trying changing cables, ports, no good.
On LG and Samsung it is working perfectly but on my viera does not.
Even updated the firmware on the TV and still no signal.

Tried turning off the autodiscovery in the BOX, did not work.
The peculiar thing is that this has started to happen as soon as RGH was done, before that it was working perfectly with the HDMI cable.

By not repairing STBY_CLK to the point that is bottom side of the torn via, are you not bypassing alot of circuitry.

I think it's well repaired. Alternate point near SB and GPU heatsink is indeed stby_clk, so it should work just fine. Try to reset video configuration few more times - at my falcon console I had to done this about 15-20 times before it worked.
