Forgive me but is there a "map" for modding a 27v42? Been searching for about an hour now for an image I can reference.

How about you have a bit of a go and I’ll see if I can provide assistance.

Looking at a Sanyo VMC-8614F.

Manual here. https://www.manualslib.com/manual/12259 ... 615fp.html

Can't find the schematics anywhere.

Can anyone point me in the right direction?

At 800 lines, seems like a great candidate to RGB mod if possible.

According to the manual it has a TDA8361 jungle IC. This has RGB inputs, most likely you'd need to mux with OSD. If you cant find a schematic, you'd need to trace yourself. Pin 22 is R, 23 G, 24 B. I think blanking is 21. You'd then inject sync at composite in.

In my experience with clones of these monitors there are usually just caps that go to ground hooked up to the RBG pins of the jungle. The OSD is post mixed into the RGB out of the jungle so no need to mux.

Just need to lift the grounded legs of the caps (or remove them and replace) on the RGB lines and feed in 75R terminated RGB. Inject 1-3V into the blanking circuit.


EDIT: Try this schematic for a similar model from my collection..

Caps C124, C123 and C122 are the RGB caps. Blanking inject 5V through a 1K resistor into the leg of Diode D104 farthest from the jungle.

Easiest mod you could ever wish to do.

It's as simple as OSD/Ext RGB mod's come. 3942, 3944 and 3946 removed and replaced with 910R twisted with 75R. The legs of each of the 75R goes to ground.

I can't guarantee this will fix your issues though.

Now just so I'm clear, I'll lift the (-) leg of the RGB caps and send the 75r RGB to that leg of the cap?

I was probably unclear. All three lines will have 75r to ground ( cross resistor from scart pin to ground for each line) then from each line run wire to neg terminal of RGB capacitor that was lifted off the board.

Does that make sense?

I have searched around the internet and not come up with much.

What i would like to do is get my sony tv rgb modded.

It is a kv lx34-m31 .

Any suggestions or links to a service manual?

The RGB will come in from the external source (Scart or RCA or VGA or BNC, whatever) . Each will need to be connected to the monitor's chassis GROUND via their own 75 ohm resistors. This will be the 75 ohm termination. The RGB lines will continue on to the lifted legs of the caps identified earlier. The legs you need to lift are the legs of the caps that are grounded, which are also farthest from the jungle.

The grounds of the "Scart or RCA or VGA or BNC, whatever" will need to be connected to monitor chassis ground (not the AC ground).

I often use RCA and connect the ground pin of the RCA socket to the ground of the chassis and connect the signal pin of the RCA socket to one leg of a 75 ohm resistor whose other leg goes to the ground pin of the RCA socket. Similar patterns can be used for Scart/VGA/BNC. Scart has pins for the "colour grounds" for instance, so does VGA...


EDIT: I missed that the 75 ohm resistors are connected to TV chassis ground

Got my Sony KV27S26 (AA-2D chassis) successfully OSD muxed. I couldn't wrap my head around how to wire inside of a SCART connector so I just made a PCB with the schematic in MarkOZLADs signature. Used RCA jacks for Sync, Audio and Video (confirmed RGB instead of composite by removing the sync jack). The blanking pin works fine on the SCART so no need to tie it directly to 5v from L003. Pictures Below. Thanks for your assistance!

One of the pictures looks really off because I was displaying a lack of sync to confirm RGB.

Spoiler: show

Hi there!

I wanted to give a big shout-out to all those who post on this thread. ❤️

If it weren't for all of us helping each other I would have never been able to complete this mod.

Without further delay.. let me present my Sony Kv-27TS29
http://imgur.com/gallery/eHa7J4F (also posted in the FB CRT collective group)

Loving the results! I can't stop thinking about modding another CRT lol

So.... hehe
I got some help to load/carry in another CRT today lol

Model: Sony Kv-27v66
Question: Is this tv able to be RGB modded?

https://www.manualslib.com/download/744 ... 27v42.html

I had a look and I am not seeing an R, G, B in on the jungle chip but I see a YS for the OSD Blanking so I am partially set lol

Any help you all could provide would be lovely :)

That model is s BA-4D and can be easily OSD Muxed.

The instructions are in this thread somewhere.

If you look at my thread about the BA-5D you’ll be able to get an idea of the theory behind the mod.

Here are the artefacts I have.

Can you tell us more about your setup?

What is outputting RGB?

What is the circuit you are using?

Hard to help when you give us very little info. Take a heap of photos of your work and maybe someone can work out what's wrong.

It's as straightforward as mods get.

Hi Mark the tv is a small philips 14gl1319 I already did OSD / Ext RGB as you said and it worked but the problem is that the image is dark and with a lot of interference like this picture and I no longer know what to do.
https://imgur.com/L9QAlel
Regarding the photos I do not have a camera just a very old phone and the image is horrible so I did not send more photos.

The photos don't need to be Picasso's, and not of the TV picture. Take photos of your wiring and the TV circuits.

OMG YES!!

That’s the model I own.

Can you share which lines you used on the schematic? That would be super helpful.

Way to go man

I have a hitachi 32fx48b and I see there is a jungle chip on the PCB and "RGB in" with blank do I just directly solder to the jungle chip or do I need some resistors in spots?

https://www.manualslib.com/manual/10097 ... e=8#manual

This tube looks great so RGB would be super nice on it.

Thanks!

Hi I am attempting my first OSD mux. I have a few questions. The set I'm attempting the mux on is a KV-20V50. It has digital RGB for the onscreen display and a separate RGB in for the closed captions. The closed captions are generated on a different board and then fed top the CXA1465AS chip.

Image

Image

The existing OSD RGB Inline Resistors are 4.7k. I used the RGB Mux calculator and came up with 690 Ohm for the Ext RGB Inline Resistors. I have a couple questions. The existing circuit has no .1uf caps. Should I put them in. On the RGB lines there are exisiting inline 0 ohm resistors near the pins I could remove and replace with .1 uf caps.

Second question, the closed captioning RGB lines each are terminated to ground with 820 ohm resistors. Does this matter? I didn't see anywhere in the calculator to figure this in.

Last question, where along the circuit do I tap in to inject the EXT RGB?

Thanks for the help!

Sony KV-20V50 looks to be exactly the same as one already tackled in this thread. It is actually a teletext/closed caption hack. No need to snip OSD/mux or anything. The text board uses a seperate set of analog RGB inputs. The OSD uses a set of digital RGB inputs that are unsuitable for analog RGB.
