RGB mod possible? Nintendo TV Sharp 19SV111

[Hoagtech]

I bought a Sharp TV with a Nintendo built into it.

It doesn't have an OSD but has an almost identical NES consumer motherboard with slightly different caps. The PPU is a consumer NES.






Is it possible to mod both the internal NES motherboard and CRT?

I am also willing to freight this beast if someone feels inclined to do so.

I can't answer you question, but cool pickup!

What a strange piece of kit! Is the cartridge connector mechanism the same as the OG NES or is it more stable, like the top loader? I would certainly get the TV RGB mod completed before attempting an NES RGB install so you dont waste your time.

Considering the rarity of these (especially with intact feet it looks like, nice find!) I definitely wouldn't want to be the first person attempting to RGB mod it. NESRGB could have odd clearance issues since who knows how it's mounted in there, and is it even easily removable to get the PPU desoldered...

Lots of unknowns, I'd encourage you to enjoy it as-is unless you can at least find pictures from other people who have attempted the same or at least shown what disassembly looks like.

EDIT there is at least a service manual and the NES part is all self-contained in that bottom section. Maybe that portion wouldn't be too bad at least.

Im wondering if a mod could exist? It's my understanding an OSD needs to be present to take over the over the OSD and blanking circuit.

Iv'e heard of people wiring directly to the neck but have heard this is not ideal and cause voltage to backcurrent to the device connected but have heard this can be safely coupled with resistors and capacitors to prevent that as well.

The set uses a nearly identical NES motherboard inside of a housing 4 times the size. There is plenty of room for any mods. I'm not worried about the NES side of RGB. Its the TV side that seems complicated as their is no Jungle IC or OSD menu to hack into.

I wouldn't mind RGB modding this set at all as long as I didn't touch the exterior. The composite picture is hard to go back to and limits the potential of the tube installed in the unit.



I was hoping that guy with the monitor on his head could chime in..

Maybe see if it's similar to this 1986 monitor that supports an S-Video mod:

But IMO that set is a near-priceless historical artifact (especially if it's still working and has the feet intact), if you wanted you could sell it and probably afford to buy multiples of just about any CRT known to man, some with RGB already included...

edit: well, maybe it's not as valuable as some PVMs/BVMs, but it's definitely way higher than most consumer sets...

Did you end up keeping it or is it still for sale?
