CR 820 new problem

[Jpowell1]

I found the bad solder connection and now the receiver clicks on so I gave it a good deoxit cleaning to clear up some scratchiness on a few of the pots and now the tuner does not work and the lights all went out
Help please

You have to be very careful taking the case on and off with those CR's. Take the case off with the dial at the end (At least that is how I do it) be careful not to snag the string or pointer...go slow.

No problems when taking it out, only after

check the fuses .

check the fuses .

All 4 checked out fine

I just checked it again and saw slight movement in the tuning needles so I put a fan on it and hopefully I just got some deoxit in the wrong place and it will dry out

Check the solder connections for TR809 ansd/or solder bridges in the same area as TR808. 809 is right beside 808.

Tap around all over the front panel and the bottom of the unit. Wiggle the heat sink, etc. They might come back on. If that's the case you have some loose grounding points.

The lamps are wired in series - parallel. If two lamps burn out in the right area, all the lamps will extinguish. Check your lamps for continuity as well as check for broken/loose lamp wires.

The two outside meter lights went out first and then recently the dial pointer and the center meter light went out
All four bulbs were replaced 2-3 years ago
Thinking about an led change

You had mentioned in one of the post an excellent source for Yamaha compatible incandescent bulbs, I recall that maybe his name was Dave. Please send his contact information again.

He is no longer in business. PM him he may still have what you need.

Do you have an alternate supplier (CR-820 & CA-2010)?
