Title: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 16, 2014, 10:29:00 pm Ok...So I m a beginner...I'll admit it. I am at a total loss right now. I bought a DK cocktail non-working for cheap and I have managed to determine it plays blind. I have recapped the audio board which has drastically improved the sound and in the process I have put in a new flyback, HOT, and recapped the chassis for this Sanyo EZ 20 13" monitor, but I still get no picture. I have no idea where I should go to check now. I have no blown fuses at the moment and no neck glow. What's next???? ???

Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: VertexGuy on August 17, 2014, 02:08:03 am 3 options.
rebuild it and pray. replace it . Or Just bite it, take the chassis out and send it to buffet. Ive been so busy lately ive been sending my chassis out. buffet is getting two of my chassis to rebuild end of this week. Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 17, 2014, 10:03:27 am I've done the cap kit, flyback, and HOT....what's left? some other caps that don't get done in the cap kit? Other pieces that I'm not sure what they are called?
Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 17, 2014, 10:45:00 am I have been following this flow chart...which I don't have an option for after both fuses are good...

I am assuming that should be adjusted down. That needs to be done while on?

That needs to be done while on? Yes, it's easiest to adjust while on. If you are afraid, you can turn it down while the monitor is off. Turn it on and test. Then, turn it off again and adjust pot accordingly if needed. Rinse and repeat until you are 108V. Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 17, 2014, 09:46:19 pm Adjusted the pot and it still hovers around 130v.... voltage regulator? Q901? This is quite the learning experience.

This is quite the learning experience. yes, replace it. Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 18, 2014, 06:01:10 am Anything else to replace if I am shotgunning this board?
Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: OriginalTHK on August 18, 2014, 06:03:51 am I am curious...who is (buffet) ???
Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 18, 2014, 09:29:30 pm Apparently he is a monitor wizard!
So I have learned how to test a pot and I think I have determined that the pot is bad and basically completely open with no resistance. Time to get a replacement and cross our fingers. Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 21, 2014, 11:03:49 pm Seriously....what the falfieaifeljfalejfael!

I am about to go put the last parts in...it better work. Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on August 29, 2014, 11:05:23 am So....all these new parts and I still can't adjust it under 130v. In fact...if I take out the B+ pot and turn it on I still get 130v....shouldn't I get 0v?

Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: Xeno_Dragon on December 19, 2014, 12:49:47 am Did you end up getting this working with the new ic401.
Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: yocke on December 21, 2014, 06:17:39 pm Is the board working? RGB are connected?
Do the tube get a glow? Title: Re: Sanyo EZ 20 13" in DK Cocktail Post by: mrdude on January 08, 2015, 10:31:30 pm So I have still not gotten this thing working despite replacing IC401, IC601, etc
I have tried a total of 3 IC601s (original, new, and from parts board). I brought it to a weekly arcade gathering for another set of eyes and it appears as if everything is working as it should, but it's not. I left with a parts chassis to try things on. I may try to see if I can get the parts chassis to work, but that's for a 19" monitor and not a 13". I just don't know what the subtle differences are other than the adjustments knobs for the picture and volume aren't on the chassis and are on a remote board instead. http://youtu.be/RuO2rFrJXwU?list=PLbHiYDImGdzCvhVYmfFw_2AlTjtyc6wVV |
