If this system is still under warranty get it to a warranty service center. This is an early stage symptom of failure with the Power Amp IC. Fender has a good warranty policy on this stuff - 1 to 3 years
If not under warranty you may want to wait until it the problem is more persistent - easier for a tech to fix - unless it IS every time right now. A good tech can identify the issue quickly once "on the bench". My 'gut' feeling is the Power Amp IC when the system is first energizing to full stable power.
The circuit is blown a couple of the connectors crossed. It is going in
protect mode to keep it from further damaging the internal electronics. Open it up and double check all connections.But if you don't have any idea how to check it then i suggest you to take it for a repair,the cost will be between $100-$150.
You have to get it serviced and replace whatever has blown up inside and after that you won't get the protected message again.
System is stuck in Progressive scan (P-SCAN on display viewer)
SITUATION: You can hear the movie playing, and you are certain all connections are correct. Your Television may not support Progressive Scan Video so all you hear is the Audio Track. Here's what to do.
Step 1: Remove DVD from player.
Step 2: Unplug from power source for 20-30 seconds, plug back into outlet.
Step 3: You need to press two buttons at the exact same time.
Step 3a: Prepare to press #1 on your HTS remote Step 3b: Prepare to press OPEN/CLOSE button on your HTS.
Step 4: Press both OPEN/CLOSE button and #1 on your remote at the same time and HOLD until P-SCAN on your HTS display turns off. Should take no more then 20 seconds max.
Step 5: Repeat all if human error occured and no improvement. Or call 1-888-PHILIPS for HTS tech support
NOTE: This solution was given to me by Philips Tech Support Division when I encountered same issue.
It depends on how the sound is heard, if the sound is distorted then the amplifier section must be checked, It can be fault in the power output IC, fault of the bias or fault in the pre- amp section.
Secondly if the sound is jarring then the speakers needs to be checked, it can be problems on the diaphragms or coils.
You will also need to check or switch source of sound to confirm if this was from a source.
Also an AF signal test and injection will confirm the stage that is effected.
These are prone to power spikes...and for that reason have a fuse located on the power supply board...known as fast blow fuses...which are glass and easy to see if they have blown..sometimes all you need to do is replace the fuse on the rear of the unit if you can locate a fuse cap...just unscrew and replace....Always unplug televisions and audio equipment and routers during power outages and thunderstorms as a preventative to blowing psu panels on electrical devices connection to your house mains for this reason .
You won't get voltage if you completely disconnect the lcp106830 power supply from the board. The connection to the front panel is required and is used as feedback. I just repaired one and found one of the power diodes faulty.
Concerning the problem...it is extremely likely that you have a corrupt EEPROM. A very common problem with this TV.The correct EEPROM (IC location IC 002) is dependent on which microprocessor (IC location IC001) and which stereo decoder (IC location IC 1001) are present on the board being repaired. Take this info to a TV tech and they will find the correct EEPROM to replace. Your TV will come back to life. If not, give me the numbers of ICs IC001 and IC1001. I will forward the correct EEPROM part #. Then the tech will repair your TV. Thanks for asking and show all hands of support!
Turn the power off, and then unplug the home theater from the wall outlet. Plug it back in after about 30 seconds, and turn it back on. If it still won't eject, then the HTS needs repair. Philips will replace it if it is still in warranty.
