[SOLVED - BROKEN DEVICE] V7Pro RF out Noise HELP

[Mbentefor]

I disconnected HDMI - no change.
I disconnected everything - no change.
I disconnected RF IN and tried to play something from USB - no change, just noise.

Have you checked the settings within the receiver.
What is your TV model number and make

Right with the HDMI CABLE everything works as it should.
What does the HDMI CABLE connect to if it is not connected to the V7 Pro.
Which means that your TV does have a HDMI input, which may be only one, that is why i require Make & Model number of your TV.
Also it is best to make up your own leads with RG6 CABLE / F Connectors / Screw Connectors.
There will be a way to sort this issue.

With these RF outputs, you get ghost harmonic channels.
The picture in the channel you show in your video has good video, so is likely not a harmonic.

Try, with the TV, doing a manual fine tuning.
Also look at the other channels you find.

To get the best out of your equipment and you do not have enough HDMI sockets on your TV, you can use a (HDMI Adapter 2 in 1 out) which has a switch
on it, to go between the two devices ie. DVD/CD Player / Satellite Receiver or FIRE STICK / VHS/DVD Player.
With the said HDMI switch, you just require the HDMI leads from the devices to the switch then one HDMI lead from the switch to the TV, you are then
making full use of getting HD pictures to the TV screen.

"Try, with the TV, doing a manual fine tuning." - I tried that. Didn't help. I manually fine tuned every channel +- 20 Mhz. No help.

"Also look at the other channels you find." - they are even worse. No sound improvement.

Also today I tried V7's AV output, it works fine.
So there is only a problem with sound via RF OUT.

At this moment I am 90% sure the product is faulty.
Especially after I noticed that when AV cable is inserted into V7, RF OUT picture has a better quality... (Sound still the same: just noise and nothing except noise)

Can you give make and model of your TV, Please.

You can't use RS232 for TTL

This was definitely the most useful comment here
Thank you, sir! I was indeed assuming the TTL is the same as RS232. Now I was able to successfully go back to the original firmware.

Unfortunately the sound problem still exists, so the verdict is "BROKEN DEVICE".
I've got my refund from the seller. It's sad I had to spend so many days on this.
But I definitely learned something!
Now I will buy myself a RF modulator and rest in peace.

Yesterday I was using my newly arrived RF to AV tuner, a old analogue TV RF to AV TV tuner, like a set top box.

I had the audio as just noise until I changed the settings in the tuner (like in the TV) for the audio, For the signals I was tuned to I needed BG sound.

I suggest you look through the menus in the TV for any setting option for format / sound.

RF to AV.
I used this as an add on to my V8 Finder Pro (AV screen only) for old school security cameras and old RF video senders.
Could power it from the Finder USB, but used power on site.
