Again, this should be C6 that appears to have a blister around the narrow ring. You can also see the acid ate away the plating on 3 legs (might be DA1).

This looks like a good example of a failed capacitor. It should be C6. Note the abnormal blister along its bottom edge.

Again, the capacitor on the left looks like C6. DA1 and TR7 is front and center. Use an acid brush with isopropyl alcohol along the legs and bottom edge of these components. I see a green tinge on the bottom of TR7.

What capacitor is on the left? Is that C6? That one looks like it "gave up the ghost". Notice the swelling/deformation along the base.

These 3 capacitors are the ones that fail the most. They are C3, C4, and C6. They appear to have swelled tops.

These red boxes are very BAD! Bad as in they look fried. I suspect the board may be physically charred in certain spots.

This is a different angle that shows capacitors C2 (left) and C4 (right). Take closer photos and verify their tops are flat or bulged out.

Take a closer look at these 2 capacitors, C16 and C17. Their tops looks bulged out, especially C17. Again, this is a sign of replacement.

Take a closer look at these 2 capacitors, C4 and C6. Their tops look bulged out, which is a sign of replacement. Take a closer photo then post. Take another look at IC3. It looks crooked. Make sure that each leg does not touch one another. This chip stores the odometer reading.

The red box shows what looks like burn marks around the solder joint. This is 1 of 4 solder joints to the speedometer face. It must be de-soldered then soldered in place when necessary.

The yellow box is the Speedometer connector, CON1. Please verify the flex print is properly seated and secured by the push-down clip. The green box is the 3-Series connector where you need to measure the VSS voltage.
