Haven't found one yet tho i'm wondering... what issue/problem are you having with the amp ?

have you had the OBD codes read ? if not get that done by someone who knows Lexus due to age of vehicle

Do you mean Circuit board?
If so then it will depend on how bad it is. For example if it has broken components on it. These would need to be replaced. A small crack that has broken the printed tracks could be repaired by soldering it back together and using wires to ensure it makes the required circuits.
Really bad damage and broken parts will make it fit for the bin!

Open and solderr the section of the audio amplifier. Possible that the IC is not conneting well when hot. Use a good solderringg iron to touch up all the joints here.
If fault still remains then use an audio test siganl and trace down to confirm on any bias loss.

Check the gain control in front panel. The material use inside them is pretty thin and weak, an could break loose when hurting during manipulation.

common problem with xti series... all the amp needs is a soft ware update contact crown and they can sort it for you... you dont have to send the amp back to them. it was a verry common fault with all the early xti amps..

maybe you should try to check for a HEAT SWITCH or RELAY FUSE or Fuse located inside the amp. the red indicator was telling you that it TRIPED maybe due to SHORTED terminals from speaker or it reached its maximum peak thats why it triped. email me if it worked. im preaty shure it will work. ciao

disconnect your load (speakers) and check.if it is o.k your problem is in speaker.if the problem goen your problem will be short circuit in speaker or cabels.-if not the problem will be in amplifier and this is not logic matter because it is new -anyway try to disconnect all inputs.if the problem goen your problem is in one of the inputs-try to connect input one by one until you find the bad one-if all above failed return your amps back to the shop.(from where you get them)

Your complaint isn't a problem at all. This is a usual characteristic of the relevant amplifier. The protection mode comes on when the main volume/bass/treble or whatever is too loud. Unfotunately, you can not overcome it. But, as they always say: It's a Sony:)
