Monitors dying :(
Black 1084S went a couple of years ago. switched off, never came on again
1084 on my c128 died a few weeks back (no sign of life when switched on) CM8833-II - screen went mental a couple of days ago, and it makes a real high pitched sound inside when switched on now - black screen). Got one working CM8833-II left.. .. What do you suggest ? Probably not worth repairing, as you can pick up em pretty cheap, but annoying. Pretty worthless broken anyway. not really after support, but just wanted to post my frustrations here. annoying to lose so many monitors recently. my 27" NEC multisync 4PG needs recapping and maintenance too. Wonder how much that will cost. I guess I should go and get some lcdtvs, but the one I have already doesnt give the best picture. do you think I can take my a1200 into pcworld or something and try some out? ![]() |

The LCD TV (Non HD) that I've been using for the last 2 years for my Amiga's via RGB Scart just died yesterday
![]() It was a great screen too, no flicker via RGB Scart with Interlaced modes & great for my consoles too. ![]() |

I have a 22" LCD HDTV Goodmans that works with my 500+ and 600 fine.

which model # ?
one of the problems is, someone finds say a good LG screen, you go to buy it and its no longer available, replaced with a newer model number (but similar looking), and then you find the new monitor isn't as good. I'll take an a600 into a few shops or something ;-) despite my issues with my current lcdtv it's still usable, but id like one with a more stable display, especially if im going to buy a couple of them for c64/amiga etc. |

I've been using an LG M227WDP with Stedys SCART cable , pretty good picture and it's a TV, and if you're really desperate you can plug a Mac or a PC in as well !

has anyone seen any lcd above 19" with a 4:3 ratio? Who decided widescreen was better for computers. for films maybe, but for coding, i need height not width!

Not for a few years I'm afraid .
It's all widescreen now . I'll have a look on Monday , but I'm pretty sure you can run the LG in "narrow screen" if you want , so code in 4:3 and watch Freeview in 16:9 . |

I think my Goodmans is an LD22#### can't remember all of it.
I just use an RCA cable for mine, just the usual you would use with any electronic appliance. |

sad but true. most CRTs die because of plastic. the voltage converters inside usually are cast in plastic, which is meant as an insulator to prevent shortening the coil. if these would be ceramic, they would last "forever". but heat makes the plastic porous, because the plasticisers evaporate.
there is not much one can do, and getting these parts replaced is very costly and usually more expensive than buying a new CRT. looking at CRTs and LCDs at work... there's a reason CRT was invented. still much more responsive, more vibrant colors... but flat is modern. ![]() you should find somebody that does repairs. maybe two or more can be frankensteined into one working model. |

Some years my 1084S died so I bought one from a friend. Some time later it died too. Luckily I could repair one with the parts of the other.

@BuZz
many LCDs have an option to rotate by 90 deg, but I guess you know that already.. |

Sony Triniton FD/Wega Line CRTs, e.g. KV21xxxx. The last great picture tube from Sony. Sure, application user/programmer probably wants a monitor, but there is nearly nothing better for lores games.

My #1 tip for someone with a dying monitor will always be to check the switches before throwing them in the bin!
They simply fail mechanically inside, giving some in between state or never reaching the on state. On 3 TVs/monitors last 20 years, all I had to do was swap or solder (permanently ON) the power switches to fix them - on RGB monitors there are often more switches though, to switch analog/digital RGB and input sources, which of course if the switch was bad could give the same symptoms as a bad on/off switch - no picture. RGB circuitry can also go bad, so check with composite to get a good diagnose, and vice versa. With a composite enhancer it could be quite good even without RGB. If you've done all that and it's up to measuring the kV (failed power supply), you might as well skip one step (and one risk of getting electrical shock) and throw it in the bin. The best way when you have 0 real monitors left is to convince a store clerk to let you attach a PAL device (Amiga, PS1, PAL DVD player with PAL DVD Disc) to a number of screens to pick one out in a store. If they won't let you, have them promise to let you return it if it can't handle PAL. |

![]() Thanks for the info. I certainly will have a read - although I'm not sure I want to mess with a monitor, im more of a software guy than hardware :-) I'll probably just try and give the broken monitors away and buy some replacements Last edited by TCD; 24 July 2011 at 18:46. |

Group buy.
I've got 3-4 monitors which need working on. Lets hire that local TV guy to fix all of them? |

Heads up people .
Voltages in a CRT monitor will kill you to death , or worse . Really , don't poke about unless you really know what you are doing ! |

I've heard that most of my life. It's not that bad.
Switch it off for a few hours and you'll be fine. Discharge with a ground wire if you're worried. If you have to work on one live put one hand in your back pocket. |
