Question about Televison & Video

1 Answer


I have the exact model and i am experiencing the same issues except for my issue is with the red color. i run the magic focus and get an error code 5 on the screen after a long pause. i have pulled the convergence board and replaced the stk392-110 chips and i also noticed that resistor RK41 was toasted, so i replaced it, but it was toasted bad enough that it was hard to read the value. i have since re-installed everything and it did not help. do you know what the value for the RK41 resistor is suppose to be
that would help tremendously
maybe together we can fix these tv's

    did you find a solution that fixed your problems, as it seems that we are in the same boat. i did get posted that the rk41 is probably rk42, and that it should be 3.9 ohms @ 1 watt. i will check and if so try it to see if it does the trick.

    that did the trick, thanks a million, replaced that resistor and it works just like new

    have a great christmas

ERROR CODE E57 indicates what?

For most questions you should supply as much information as possible, especially manufacturer & model #.

I'm sure error codes are different by manufacturer.

I found this answer for an electrolux;
Regrettably, error codes E57 and E58 could mean a number of issues, but primarily that the motor is overheating or a higher-than-usual motor current caused by other issues. Typically, an experienced technician would remove the belt to check the motor and motor pulley to ensure all is in working order first. Their next step would be to check the tub pulley and tub bearings. Last items they would examine would be the drive motor and speed control board by ohm measurement. Once the tech has ruled out a number of possibilities, he or she can pinpoint the exact problem and the necessary part to fix the issue. Since parts can often be quite costly, I would personally recommend reaching out to a qualified tech who can accurately diagnose the issue your unit is experiencing.

Magic focus --blue and yellow sag in the upper left area of the screen

This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.

Error 2 on usb reading

I have also been experiencing the very frustrating "Error Code 2" issue half way thru the calibration process. Sometimes the error occurs during measurement No. 1; other times on the 2nd or 3rd measurement.
I am running a MacBookPro running OSX 10.7 (Lion Server) w/ Vmware Fusion v4.1.1 and Windows XP (SP2).
After experiencing over a dozen of failed attempts to calibrate, I started to tweak the Windows setup.
I found out after some experimentation that the issue is not so much the Alpine Imprint S/W, but much so with the USB/Serial interface hardware. The S/W has issues with error recovery, which forces the user to close and restart the application if an exception is encountered...but if the exception can be avoided in the first hand, it runs fine!
Would suggest to try the following tweaks to address the Error Code 2 issue:
(1) If using Vmware Fusion, ensure that the USB/Serial is connected. On the VMWare Fusion menu, select Virtual Machine->USB & Bluetooth->Connect Future Devices USB<->Serial. Ensure this is connected first before launching the Alpine Imprint Sound Manger (v2.10) application;
(2) The USB cable that comes with the calibration kit is quite long and I am not sure the shielding is that good. So try to straighten the cable out and not allow it to coil when connecting to laptop; this should reduce any potential interference and signal degenerating issues;
(3) Within XP, open up Control Panel->Administrative Tools->Computer Management->Device Manager, locate under "Ports" the corresponding port that the USB<->Serial interface emulates. Usually this is USB Serial Port (COM3).
Open up the Port Settings under its properties menu.Apply the following override settings:
Bits per second = 921,600 (or 115,200 is fine as well)Parity=EvenFlow Control=Hardware
Click "Advanced" button and override the following settings:Minimum Read Timeout (msec) = 10,000Minimum Write Timeou (msec) = 10,000
These simple override setting works like magic for me.I was able to complete all the 6 measures without a glitch.Hope this works for your setup as well.
PS. For subwoofer calibration I also found useful tuning down the gain beforehand on the amplifier. On the Alpine head unit, set the Subwoofer output level to very low (close to zero). On the amp-side (I am using 3 x Pioneer PRS-D4200F) set the gain switch anti-clockwise to a voltage slightly above 2V (do not over do this). Then after the calibration has completed, set it to just below 2V (clockwise rotation) to slightly elevate the output. The remaining subwoofer gain adjustment can now be done comfortably from the head unit's subwoofer output control.
