Default Radio Shack HTX-202 low transmit power

Just over a year ago, during an event our club provides communications
for, my Radio Shack HTX-202 ht started intermittently transmitting at
low power even when set to "high". Since then it has gone to low
power all the time. This happens using battery or external power with
the whip or external antenna. The Google search revealed KB8ZCJ's fix
for his problem but I don't want to solder unnecessarily and am not
convinced that mine has the same malfunction as his did.
http://www.phreak.org/radio/mods/htx202fx.txt The LCD's on mine light
up as low power.

And the http://www.mods.dk/view.php?ArticleId=2721 page told how to,
apparently, make the radio permanantly either high or low power. Any
recommendations on a switch replacement or a repair facility?

Thank you for your efforts. Remove nospam for email reply.

Update. I started to try the mod below. Get the switch cover off
about half way and decided to stop for fear of permanently damaging
the radio. Put it all back together. Works fine now. Full power
restored.

Curious!

A few years ago, my own HTX-202 came up with an error code that
indicated that the PLL had failed to lock. I decided to open it up to
take a look, and while I was at it to perform a simple mod intended to
remove a birdie on 146.76.

When I got it open, I took a look, chickened out and carefully put it
back together again. It has worked perfectly ever since -- birdie and all.

I wonder what opening and closing the case has to do with fixing the
control circuitry/software in that little box.

You scared it. The more technically astute the repairperson, the faster
the radio restores itself.

A bad solder joint would be a good first guess. It would be common to all
those issues listed thus far. A component bumped just enough to get it to
make contact. OR a mechanical connection like a ground - disturbed when unit
was disassembled and reassembled.
