Hey everyone, this is my first post here.

I've been working on this unit for the past few days, the problem is movies have black and white image or intermitent color.
Sometimes if the screen is blue it gets pink, like some strips of colors, or human face is green.

I've tried messing with all the pots I could find and while sometimes it gets close, in the end it doesn't solve it.

What I've done so far, full recap of all 80 or something caps on the video board and full recap of the RGB board (20 or so caps) in the back.
Audio is fantastic on both analogue output and digital.
Discs play just fine it's just the color.

I'm considering if the crystal oscilator might be the problem but I can't find any info when looking at the model printed on it.
Also since I've messed up with all the potentiometers this unit is uncalibrated again and having no osciloscope I wonder if it's possible to get those right by just looking at the picture on the tv.

Any suggestion or help would be deeply appreciated.

Hi there.
Since the potentiometers and now past the point of calibration guess work won't help... You really need an oscilloscope and potentially a frequency counter to get the colour subcarrier correct. It changes from 4.433Mhz in PAL to a different frequency in NTSC. Because the re-calibration process usually has to be done in a specific order (per the service manual) it impossible to do it by guesswork or looking at the LD output..Some of the calibration must be done in service mode I've found. Sorry to be the bringer of bad news but moving pots without first marking their original position can cause huge headaches and frustrations.. I made that mistake a while back when I was new to this world

In some instances it's just a tiny tweak that can throw off a colour decoder stage because the decoders need to be calibrated to precise frequencies. Crystals usually are fixed and oscillate and fixed frequencies if you had a scope you could see if the crystal was working and near the frequency it should be. Do you have a service manual for your CLD-A100? if so that should have "Electrical" adjustment section that walks you through setting up the video circuitry. Mine is a CLD-1750 and honestly I've not touched the electrical bit because I don't have the right tools/equipment and I am a trained TV repair engineer.

Replacing the electrolytic caps is a good thing to do IF it's proved to be degrading or stopping the signal. There are ESR meters on ebay to detect high resistance electrolytic caps without the need to desolder the cap Very useful.

1: See if you can find a service manual.
2: See if you can get help of a local repair shop to set up the colour decoders again to factory specs.

I hope this advice helps you out.

strikemrb1 is spot on. You need a frequency counter to set it back to 3.579545Mhz.

I have a service manual for your CLD-A100. But I can't seem to attach it here... It will be a huge help for you or a local service shop to get all of those potentiometers back to a working condition.

You can email it to manual at lddb.com

What happens after I email it to that address? DO moderators post it somewhere?

Service manual emailed to address above..

Julien (admin) will post it to manuals.lddb.com - I do see there is already this here (I should have checked first): https://manuals.lddb.com/LD_Players/Pio ... /CLD-A100/ but you might have a different version or better scan.

Today I took the day to work on it, so I looked at some images online that had the pots positioned as default and bang! it worked to revert mine.
Colors were almost perfect but.... I believe I've short something, the unit is dead after so many days of work on it.

Talking to a friend he mentioned that this unit has tons of fuses but I only see one?

The service manual only shows F001.

Where can I find the fuses?

Found the fuses, those IPC. I'm going to check those tomorrow. It's really late here but I'm almost there if I can revive this unit.
