I am not giving up my B&O LX2800!

Okay, spilled coffee in the TV. A good dash. Because the cup was on top.

Problem to align picture, a small grey stripe on top and R108 turned all the way down.

After taking out all boards and cleaning them, I discovered two loose resistors

just by POT 108. One was kinda big, other small.

Installed boards again, dried... washed them in water...

After re-soldering them, picture aligned.

Everything 100% now.

Not my first choice. IPA (Isopropyl Alcohol) would be a lot better.
Trapped and conducting water inside coils and underneath IC's, multi-plugs, resistors and capacitors isn't something you want and then there's the chance of corrosion.
Of course drying with a blowdryer minimises the problems but did you before applying power ?
Really nothing much else to be said. Who put's a cup of coffee on top of a TV ? Especially one you're happy about.
Keep an eye out for corrosion over the next month.
Good luck.

No worries, only one IC got covered in coffee. Rinsed circuit board under tap water... used hair drier. Better than new!

Lesson learned.

Now I need another restoration project.

Yes.. fair enough way to deal with coffee.. better than letting it dry while hunting down some isopropyl. In phone world we often use water to wash out the worst of any contamination (anybody for urinal phone? ewwwwww) before dumping the whole board into a bath of 99% spirit to displace the remaining water, then we bake the board in an oven for around 30 minutes at 80C to drive off any remaining water and spirit.

The spirit can them be bottled and stored away for next time until it starts to look a bit mucky.. that's when my spirit stove comes into play. I hear industrially they distil the contaminated spirit back to 99% over and over.

25 years ago I had a placement at BBC Radio in 'outside studios' (anything not in BH). Coffee-in-the-Calrec was dealt with by removing the affected channel strip, flushing it in the toilet, and sitting it on the radiator!

Clean tap water is very suitable to clean boards and rubber pads.

I repair many remotes by dismantling them, and using good dish washing liquid and a quick rinse in tap water.

I then let it dry using a fan with little or no heat.

Now to enjoy some TV and
