Title: PC 10 duel monitor
Post by: Antman on September 05, 2014, 12:44:01 am
Going to look at a PC 10 duel tomorrow

Guy said the board works but both monitors are out
And it should be full of games

If it's just cap kits im good to fix it or a PS

WISH ME LUCK!   

Any thoughts of  what to check first for the duel  monitor ?

Should I plug it in to try and hear it make noise before I buy?
Should be full of games.   "No exact number given in text"
"Or game titles"
$225

If its full of games, 225 is a great price IMO even if the monitors are out. Plenty of Sanyo guys here to help you. When I try to fix Sanyos, I make them worse  :(

Well I got the machine and I think I got a good score!

I do believe it just needs a cap kit x2

The pcb seams to get power and lights on the board illuminate
Checked the power supply and all voltages are working
I checked the voltage to the monitor and it's getting the 100v it wants so it must be cap kits

I guess the sound boards are in with the monitor board area
Both have no sound or signs of life from the monitor

I ordered 2x deluxe cap kits and 2 "hot" from bob Roberts !

The cab was.  FILTHY FILTHY FILTHY !!

Slight screen burn in the top monitor that I didn't even see until I took of the glass to clean it

The cab has the light gun and holster !

Packed full of games
King fu
Rygar
Contra
1942
Golf
Hogans ally
Mario bros
Super mario bros
And 2 others I forget

He also gave me 4 big case like boxes for Nintendo vs

The case has a marque , glass for marque, license sticker, and game chips

4 cases.   Can these be used in the PC 10? Or is it a vs only?


THINK I SCORED GOOD!

Two dead monitors

Took the top one out tested and removed the chassis

Not getting any b+ reading on ether monitor

Ordered new cap kit and flyback for both just to have them
And new hots for both.  Both hots currently check good.

No neck glow  no sound  fuse is good.
Diaods 401-404 check good I think

What else should I check for a dead board?

All caps look normal ,  no explodes or anything noticeable
No cold solder I can find.
Continuity of traces check good

Any help is appreciated! And thanks !

Rush and attack
Double dribble are the other 2 games

Found a bad trace on the bottom monitor
Jumper installed and monitor is great !

The top monitor got a cap kit installed already but I found a ceramic resistor blown and am waiting for it to arrive as radio hack did not stock the 7w 1.5 ohm or acceptable

I believe after I replace it the top monitor will be good !


I bought a cap kit delux, flyback,HOT.voltage reg,and filter cap for both but only fixed the trace on the bottom monitor to fire it up!
