Amiga 500 plus with boot problem

[goul]

Hi all,

i need help to boot my amiga. I cleaned all chips and replaced the faulty battery with a CR2032 one ( i found a guide for this).

It boot with showing a white screen, but the game get loaded, with video glitches, only if i insert the floppy before power on the amiga but with video.

hi again,

@Oldsmobile_Mike
the model is amiga 500 plus with no expansion card
I don't get the "insert disk" screen, just white.
I'll try a wb disk tomorrow, but games boot.
Caps lock doesn't blink.
Rarely on boot up, just a black screen and video signal lost.

@jdupuis
I'll check all tomorrow. However i got the white screen before i removed them.

PS: i attached a "video glitch" example

Hi all again,

few updates.

@vince_6: i just bought an amiga rgb to scart cable replacement for the old amiga 520 adapter. Same screen with the amiga 520, the new cable and composite output.

@paul1981: The fault was present as i connected it, then i cleaned inside and replaced the battery. the battery leaked some acid.

@Oldsmobile_Mike: the board revision is 8A and the rom chip is v2-04. I suppose i can load the workbench (see the attachment). The floppy clicks also with no "insert disk" screen (maybe just a video problem?) and i toggle the caps lock

I'll check and clean denise once asap.

there is a video problem for sure because i saw a guru meditation disapper on boot but clicking the mouse button the amiga has been resetted.

Thanks all.

Hi again,

game sound is good and i got a red screen today.
If i have to load the Workbench in order to run a memtest, as i wrote, probably  i can't run it because of graphic corruption.

The systems are PAL and tomorrow i'll check on a different PAL tv.

Can i try with a new rom, denise or both?
I found different roms but what is the best for my amiga 500 plus between 3.1, 2.04 or cloanto 3.1?

Thanks all.

Thanks all,

my amiga is working now!

I replaced the agnus. Finally i got the "insert disk" screen with no graphic corruptions.
