REPAIR GUIDE - TurboExpress/PC Engine GT: Video Fix

[Duo_R]

Give that a shot, swap screens on both units and see what happens

Are you sure the unit is even powering up? Do you hear sound? Sorry if you answered this already back there, I'm way too lazy to backtrack through messages.

If your friend f*cked something up when he was haphazardly replacing caps, he could have easily blown the unit's fuse. It goes south at the drop of a hat. Trust me, I've been there.

Hi People!

alas - I was so happy when I found this repair guide, because my PCE-GTE had exactly the symptoms described here (backlight + sound but no piture). I have thorougly followed the instruction and replaced the capacitator. Unfortunately the problem did not go away. The cpacitator seems to be firmly in place. Any hints? 

[Duo_R]

need more information to really give some guidance. Did this unit work before for you? Did the install go smoothly? Do you have pics of the install area?

Yes the unit did in fact work before. However the display went dark after some time leaving the backlight on. When I removed the old capacitator, it seemed that it had actually bled. Please have a look at the picture, to check if the new cap is correctly installed. For me it really appears to be.



hints?   O:)

The thought occurs that one of the solder pads may have inadvertently been removed when you took off the old cap.

[stimpy]

I that turned out to be true - can you think of a way to fix it? Thanks.

Which pad was lifted?

[stimpy]

Sorry, I meant: "If that turned out to be true ..."
I'll need to check first.

Which pad was lifted?

[Duo_R]

If you did we can find somewhere else to solder. But need to know specifics.    

[stimpy]

OK then - after having a closer look, i would say that the left pad (see picture above) is still in place. If you look at spot where the left pin of the cap is attached to the board - you can notice some black spots around the solder. That may indicate that the right pad was in fact lifted. I bought a desoldering wick today. Should I detach the new cap?

Do u have an ohmmeter?

[stimpy]

No - I'm not a soldering freak to be honest. Perhaps a friend of mine can lend me one.

Also - of course in my last post I was talking about the _right_ pin having black spots around the attached area - sorry.

[stimpy]

Hmmm ... it seems I cannot get my hands on an ohmmeter so easily. AFAIK, those things are expensive. Do you think I definitely need one for the fix?

I bought a cheap one at Harbor Freight.
