Hi,, Yes all the problems are linked, They are all controlled by the same power supply, or the ACC (accessory) supply unit. This is just a fancy way of saying a fuse and a relay. Now there are 2 fuses , 1 in the kick panel under the dash by the drivers side, and the second is in the fuse box under the hood. the relay is in the fuse box under the hood. from what your describing, seems like of of them has run slack and shorting out.

  1. locate kickpanel
  2. remove cover , under the cover is a diagram showing the fuses, locate the acc fuse or accessory fuse.
  3. pull it, make sure its good, replace it.
  4. close ip panel and pop hood
  5. locate the fuse box
  6. locate the acc fuse or accessory fuse using the diagram on the cover
  7. pull it make sure its good replace it
  8. locate and pull the accessory relay
  9. pull it, and replace it.
thats it for now,, that should solve your problem however its not the only possible cause just simply the most likely, remember i aint on the spot so you are my eyes and ears, if this doesn't work respond and we'll try another approach.. which we'll call my second best guess.

My 2006 LX470 seems to have a music-loving ghost. The CD & radio will turn itself on and the CD will switch to radio & vice versa. This has happened 8-10 times in the past month. Any thoughts?

The Phantom rides in style......Awesome vehicle
Sounds like an internal fault in the audio switching, check your warranty, since that LX might still be under the 4 years and if so get to a dealer ASAP.
You could go online to Lexus owners club at Lexus .com and search the issue too. Never heard of this one but the LX is a niche market so I don't see tons of them....Is yours a Mark Levinson sound system?It will say on the dash.

LS430 radio display went blank; letters, numbers etc. won't appear but there is a white backlight and the radio plays fine. Is there a simple fix short of replacing the radio? thanks in advance.

Im sorry to be the one to inform you but its bad news. Once the liquid crystal display fails, there is no more hope. It may come back on by itself but it will surly fail again. Replacement will be inevitable.
