Composite of screen output problems.

Hello, Mikka_A Mik> 41 it’s heating up, burning. You can boil it. At the exit (10th leg) - what should Mik> be? The same as on D40 (10th leg), shorter pixels running along with the beam. On D41 they just linger (like four parrots). In short, try to depict some kind of art on the screen (just type in letters), if on D40 the picture is in doubt, but on D41 it’s not, then it probably died D41 (yes, rather All in all, she’s warming up so much).

Hello, Mikka_A Mik> Respect to FAN But the problem is :cool; Mik>; 2 Moderators. The topic can be closed and deleted. Thank you. It’s better to create a non-sinkable FAQ and include this incident, because I don’t remember that he was cited as an example somewhere. (it will be useful for newbies and those simply interested)

Hello, Mikka_A IMHO something has burned out from the pixel output garland (the cursor is blinking). I'll torment the D41 and how it steers, as well as the D40 and D39.

Hello, Mikka_A with video memory... Well, well. PeTse has completely weaned people off speck. In spec Video memory is just memory. It is unlikely that anything happened to her apart from main memory. The problem is in the formation of the video signal. You either don't have a TV understands RGB, or simply all the wiring R, G and B are plugged into one input, and without mixing with resistors. Or the resistors are completely broken. In general, in the wires matter. Most likely, you don’t even need to open the case to fix it.

Hello, All Hello everyone. I made a subject here - http://sblive.narod.ru/ZX-Spectrum/Composite/Composite.htm - Even working, but there is a problem with the display. You turn on the car, the car starts, a black screen pops up, white border, black the screen blinks for a second (as expected, but the red stripes from bottom to top do not are viewed) and the screen remains black. And the border is white. If you blindly, say, tell him BORDER 0, then he perceives it perfectly team and paints the border black. At the same time, when you say BORDER, you can see that the cursor pops up and blinks. That is, there is a white blinking cursor square on a black background. It is clear that something is wrong with the “video memory”. Tell me something, otherwise the fantasy is over.... :v2_down; It turned out; broken register D41. I changed it and everything started working. Respect to FAN 2 Moderators. The topic can be closed and deleted. Thank you.

Hello fan Vla> In general, the problem is in the wires. Most likely you don’t even need to open the case Vla> to repair. Vla> If everything were so simple, then I wouldn’t write here... :o What do you think - if nothing is visible except a flashing sign, and the curb changes colors from 0 to 7? :eek; that is; ALL colors are displayed, but it doesn’t work, if you can call it that, although you don’t care I like pussy terms :cool; ,character generator.; :v2_rolley fan> Pomuchy D41 and how it steers, as well as D40 and D39. 41 is heating up, burning. You can boil it. At the exit (10th leg) - what should happen? I have one there. but if 9 is set to 0, then to 1, and vice versa - 10 is switched to 0. (maybe, of course, the register doesn’t count correctly....) 40-39 - there are short needles, positive... (on 10 legs). What, in theory, should be there?
