LED front panel displays

you have to have that led replaced by a tech

This is how to reset the receiver to factory default- not sure if it is the same reset you would do for an amp error:

Resetting the system
Use this procedure to reset all the receiver's settings to
the factory default. Use the front panel controls to do this.
1 Switch the receiver into standby.
2 While holding down the front panel STEREO/A.L.C
button, press and hold u STANDBY/ON for about two
seconds.
The display shows RESET?.
3 Press the front panel AUTO SURR/STREAM DIRECT
button.
The display shows OK.
4 Press HOME THX to confirm.
OK appears in the display to indicate that the receiver
has been reset to the factory default settings.
Note that all settings will be saved, even if the
receiver is unplugged.

Unfortunately, amp errors are usually not fixable and require you to bring the receiver on for repairs or just buy a new receiver.


THANK YOU AGAIN SO MUCH! I basically got through the 1st step or so and the thing came right back on like nothing had ever happened. Although, I think what ended up working for me was actually pressing and holding the STANDBY/ON button with the AUTO SURR/STREAM DIRECT button together for a few seconds....I didn't have to reset to factory settings, nor did I have to do step 3 or 4.

Now the receiver is working just fine like nothing ever happened. All of the input AND output speaker channels all seem to be functioning normally and in peak form, and I've made sure that I have the area around the receiver well ventilated. So....thank you, again...for getting back to where I really wanted to be without having to go through the hassles of disconnecting everything and having it serviced with possible $ and time expenses.

It is a cable provider setup within the menu. On charter here are the steps - menu, TV guide main menu, setup, Cable box setup, front LED display.... I don't know what these other people are trying to answer for you...lol. You can also adjust the brightness display by pressing power followed by menu (starting with the tv on).

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

A search of prince channel site for 735 timer sent me to the 740 timer >> their other models wer 755 and 840

Here's the prince castle page:
http://www.princecastle.com/products/timers_740series_single-display.asp

Here's the 2 instruction guides:
740 horizontal
740 vertical

The timer is a multi-channel countdown timer which means it can control multiple electrical devices separate from each other
Set the french fry cooker to tun on for 5 minutes
Set the dryer to come on for 10 minutes
Set the blower to come on for 1 hour
Set each item for different lengths of time
The item with least amount of time left shows on the screen

To program timer
Press and hold Prince Castle logo for six seconds
Time displays will change from " ----" to "PROG"

Press timer channel to be programmed
LED indicator light will turn yellow and beep will sound

Current programmed time will display (for example it might show 5 minutes 20 seconds)
Time value will indicate either H:M (hours-minutes) or M:S (minutes-second)

Press SCAN/UP arrow or SCAN/DOWN arrow to change program time
These arrows are located next to Prince Castle logo

If you want H:M instead of M:S, then press and hold SCAN/UP button
When display reaches 59:59 it will automatically change to 1:00 Hour
LED indicator light switches from M:S to H:M

Now you programmed first channel, click next channel and repeat steps above

To FINISH programming, press Prince Castle logo for a moment, and programs are saved
