Zoga 101 - no video through RCA, audio OK

So I ordered Zoga NES toploader clone from Aliexpress. Took quite a while to arrive and when it finally did, there was a label on the box saying that the package had arrived as damaged to my country, the label was attached by my country's post. The package was also wet.

The console powers on and audio works without any issues but there is no video. In addition of composite RCA connectors this console has RF tuner or so it atleast claims and indeed by using it I can get some kind of video output, enough to see that there might be video game running. The problem is, I'm pretty sure the RF tuner is for US and I live in Europe so my TV cannot really show decent picture.

I have tried to resolder the video connector pins etc. but it hasn't changed anything. I'm not an expert which I believe you can tell, but could it be that the transistor is bad?

I took one quick picture, I have to resume this tomorrow or later date.

UPDATE: It seems that only my old CRT TV can pick up the sound, my modern LCD TV cannot. My CRT has RCA inputs on the front but with the modern I have to use RCA to SCART -converter, the converter I'm using has worked fine with all other consoles.

black is rf, yellow is composite video and white is audio.

 

You can always get a refund if it's damaged.

 

^ As above

Are there any other transistors near the cartridge connector? More pics would be great to see if anything else can be done.

 

Yes, I already raised dispute, took several photos and recorded opening of the package as well as testing. Seller has not yet responded.

First I thought I shouldn't open the console before dispute has ended, but then again of course I will not be sending this back since it's so expensive so I'll hope either the seller or Aliexpress will refund. I didn't ask for full refund since game cartridge which was included works in genuine NES.

 

Backside of the power / av connector board.


Tested ribbon cable continuity, cables seem to be good.

If the transistor can be suspected, I have these available and maybe one another type, have to look:



But I don't know if these are compatible.

UPDATE: Tried replacing transistor, nothing changed.

Console was fixed by performing AV mod using new transistor and bypassing most of the AV board.
