Over driven color

Over drive lamp fails. I guess or is it flashing for errors.
the service manual covers all that , buy it and read ?
problems with 4R70e transmission , not told. clearly
scanning the PCM now is what is best done.
any time a transmission like this fails to shift the PCM tells you why or how it was detected. via what. with DTC codes
why not scan it.?

OD function. real name is 4th gear is overdriven
so if the tranny stops at 3rd gear we say 4th gear is dead.
4th gear is 0.70: 1 ratio.
engine spins 3/4 turn(near) and drive shift goes 1 full turn
as in overdriven gear.
now lets talk dead 4th gear, all the ways it can happen
sadly lots. for sure you not scanning the PCM first to see why.
speed sensors lie
transmission sensor shows overheating,
engine load is too high. 4th gear makes that worse so why wreck clutch packs doing that and it sure does not.
learn the transmissions are shifted by speed and loads.
load on the engine if tops.
VSS errors, OSS errors
and more, even a weak engine, is a cause.
sorry but this is how it all works
and you can not fix modern cars and trucks lacking a good scan tool..

Depends when it makes these crackling noises.

If it's when the sub isn't being driven, then it could be the amp. (Check for bulging capacitors on the amp board). If it's when you move cables about then it could be a broken lead or a dry solder joint on one of the inputs.

If the crackling is when the sub is running then it might be the voice coil has distorted due to being overdriven with a poor and highly distorted signal.

You might have overdriven the amps and burned them out. Might be too expensive to repair and maybe cheaper to replace the receiver.

Your model does not have a color wheel. It is lcd driven, which means you must replace the entire Optical Engine. Here is the part # 939P977020. I found a price of $385.00.

Any foreign bodies inside the driver bay, or something magnetic? Just a thought.

Unless they've beed damaged though being overdriven

I can't find a manual. If it has both analog and digital outputs, compare both for sound quality and report the results. Also try them on different INputs of your electronics to eliminate that as a problem.

Let's examine THAT side, too. What are the components involved and how are they connected?

did you check the board could be that issue check with a tech guy and verify that

woofer circuit problem! it could have been overdriven causing overload to the component on the circuit. check woofer circuit for damage components, most likely power ICs and capacitors bulging

clipping as indicated by its light? if so then you have overdriven your output. i dont know about Crown their protection but normally such indication you have problem with either your load speakers maybe shorted but still audible or maybe your input stage overdriven also.

I had the same problem with a PS2 connected to a small Sanyo TV. To fix it, while the game was playing I pressed a button on the remote control adjacent to an icon that resembles a square with a black dot in the bottom right hand corner. On my remote the button is directly behind the TV/AV button. As you press the button, one press at a time, this takes you through the various video format options available, including PAL, NTSC, Auto etc. When you reach the correct format the colour will return to your game.
In my case, I suspect this button was accidentaly pressed instead of the TV/AV button.
I hope this helps someone else as the problem had driven me mad all day before I stumbled over the solution.
