Mitsubishi VS50VA2 rolls for the first minute after turn on.

Look for red capacitors by jungle IC.Look here.

This symptom is typical of the infamous PIP module with the leaky electrolytics. If the corrosion has not become so bad that the board is unrepairable, you can change all of the surface mount caps and clean up the corrosion. If the traces are eaten up or the black corrosion has reached the IC, don't bother. Just bypass it.

The details of the bypass and repairs of the PIP modules can be found in the archives of this group and on the NESDA-Ohio organization site.

There have also been some sets in this chassis series with problems on the 9 and 12 volt lines. Check the caps on those lines.

Concur! This is 99% surely a PIP issue. Bypass that beast!

I've done a few PIP bypasses on 27" sets. Is the board used in these projections and the procedure for bypass the same as the 27's? Lenny

Yes. Essentially the same. I think the connectors might be lablelled differently, but we use the same bypass technique.

Note that only a few models of the RPTVs used these. A lot more of the direct view sets did.
