Baird LC-37W18S intermittent red-green-blue-white screen
« on: January 05, 2012,08:11:01 »
Happy New Year to all.

I had fixed one of these Xoceco made sets last spring - inverter had 2 large ceramic caps in series with a transformer primary - both of which had cracked solder joints.

Now the same set has a different problem - it will be fine for between a few minutes and a few hours, before displaying a single colour screen - which changes every second or so (i.e. red, blue, green, white....). The set does not respond to the remote after getting into this state, and power cycling always seems to fix it.  It is as if the processor has crashed or entered a set-up mode.

Daddymayhem had a set with a similar issue about a year ago, someone said EPROM but this is intermittent so I would doubt EPROM. Service manual was included with that post (THANKS Daddymayhem).

Before I get my hands on the set again, armed with freezer spray, anyone seen this or got any advice?

Thanks in advance.

Matt
