Ok, I originally had a Sony Wega Widescreen (CRT) and it run like a trooper, displayed everything thrown at it and it could stand being tated.
I subsequently decided that I should get an LCD telly and get a TATEable wall mount for convenience and to get into the HD era.
I plumped for a Sharp Aquos (26") and all was well until I found out that;
1) It did not Like NTSC through composite - just got black and white. I had to then use a Scart adapter as it was fine through the Scart ports. -ok, maybee not so bad as I have 2 Scart sockets.
2) It hated my s-vhs connection for my Jpn PS2 but didn't mind my Jpn Cube. - again not so bad as I have a component cable for the PS2.
But, worst of all:-
3) Major problems with my Sigma Supergun, some early pcb's run ok with a little flicker, but Progear flicks left and right and Ketsui rolls endlessly. Problems also with Batrider and Bakkraid.
I eventually dedided this year to upgrade my LCD and pass it on to my parents, so to be sure I took my supergun to a number of retailers to test and:
Samsung r73 series - Supergun output scrolls
New Sharp Aquos - supergun scrolls
Hitachi latest - supergun scrolls
Sony Bravia - flicker on screen, that settles then starts again
Now what's going on, it would appear that most PAL LCD TV's out there are super fussy with my supergun.
To put this into context, a while back I picked up a cheapy lcd (17") for the spare room and guess what? Despite it being a really dodgy brand, it displayed everything I threw at it including my supergun.
I'm really gutted, I have gone back to using my Sony CRT, although I am tempted to maybee check out a few naff LCD brands in the 26" size range as they may wish to work.
The Sony Bravia soooo nearly worked and I must say that out of all the LCD TV's I have looked at this is the best by far. Possibly some fannying around in the service menu may solve the problem, but I'm not going to mess with that and, well when i tried to convince Sharp to investigate, they basically told me it was all my fault. Last time I buy from Sharp!
So which brands and models of LCD tellys do you guys use?
Branded LCD TV's and Superguns a no-no :( (for Euro only)?

You did take into consideration the pin that tells the telly to switch to RGB mode right? I had rolling of all sorst a while ago too when that pin was pushed back (didn't make contact) and my PAL Saturn doesn't pump enough juice through to that pin 
Or it could be the frequency rates. And keep in mind that these new tv are all digital, they have to convert evrything so if the conversion process is too strickt or lacks support for certain (unexpected) frequencies and resolutions. what you did is what more people should do. Take your console to the store and try before you buy to avoid dissapointment. And even if it doesn't seem to work to satisfactory after a while, take it back, ask for your money back.
I'm curious to find out the true answer

At first I thought it might be Scart pin outs causing a problem, but the composite output also has the same effect.
I am certain it is a refresh / frequency issue and I am also sure that the set could be 'tuned' via the service menu.
For the time being I will make use of my 'old' Wega which gives better colour depth anyway.
Scanlines are cool too

it's not a problem with "PAL" LCDs, it's an incompatibility between the narrow TV system specs and the wide jamma specs when it comes to refresh rates and or sync widths. It's hard to solve the problem (you need to use sync modifier ICs), but you can have your supergun run through an upscaler and output in VGA instead of RGB. Doesn't have to be a $200-300 machine, a $50 CGA to VGA adapter will do the trick as well.Now what's going on, it would appear that most PAL LCD TV's out there are super fussy with my supergun.
I've had several Cave PCBs run on various of my LCDs (Samsung, LG und now a Sony XBR5) and this includes Ketsui.
it depends on how good your TV would handle the RGB input, but in my experience RGBs is heavily mistreated and VGA is better all the time. Don't forget that you're dealing with progressive displays, so any RGB input always has to be upconverted first before being displayed.how does the VGA picture compare to RGB?
