The protect message is an indication that a problem was found at the final stage of the amplifier. Typically, this is caused by defective output transistors. A confirmation of this can be made by removing the speaker wires and turning on the unit. If the protect message still appears, the problem is internal to the unit and it will require repair. The DAV series of units are not the easiest to work on and replacement parts are limited. I would suggest that you get a detailed repair estimate from an authorized Sony service center. Post the results here and we should be able to walk you throught the actual repair.

I have tcl led m. no 24d20 only displays tcl logo and then no responce


Unplug the tv and hold the on/off switch on the tv (not remote) for 30 seconds. This should clear any power left in your electronic boards. Then plug it back in and try again. Also try bringing up the menu, and see if there's an option "factory default", and try that.

Printer unable to clean


This most likely means that the over flow tank is full. You can order a replacement tank but you have to disassemble the printer pretty far to get to it. You would also need to reset the counter so ..... if you want you can just reset the counter. Doing this without replacing the Ink Absorber will mean that once it is truly full it will leak into the printer itself. Do so at your own risk, but then again these are cheap printers....

Brother Maintenance Mode Commands:
- Quickly press Menu/Set * 2 8 6 4 to enter maintenance mode.
- Display should read maintenance.
- Press one or more of the maintenance mode commands below. After each command display should read re-init for a few moments then redisplay maintenance.
- Press 99 to exit the maintenance mode.
Maintenance mode commands:
01 Full RAM clear (see 91 below for retaining user programming)
02 scanner initialize (feed a white sheet, then a black sheet)
05 white level
09 print test
10 modify soft switches
11 print configuration list
16 panel test
19 CML test
20 signal test
21 tonal test
23 filter RX
54 scan edge
55 scanner area
66 test print memo
75 display drum life (if enabled on laser models)
76 reset drum life counter (laser models)
91 parameter initialize (user programming remains intact)
95 protection
99 Exit maintenance mode"

I would use the 01 and reset everything. Otherwise you can go through the 91 parameter list till you find the counter.

The pen drive indicates write protected and does not allow to write new files.


Three possible sources for this problem, and three separate solutions.
The following procedures assume your flash drive is assigned by MSDOS to drive E:
---------------------------------------------------------------------------------------------------------------------------
PROBLEM 1: Pen drive write-protect switch set
SOLUTION: move the tiny switch on the pen drive from the icon of a padlock locked
toward the icon of a padlock unlocked
---------------------------------------------------------------------------------------------------------------------------
PROBLEM 2: MSDOS attribute set incorrectly on any/all files on pen drive
HOW TO DISPLAY CURRENT SETTING: START > Run... > cmd
C:\> E:
E:\> attrib /S /D

HOW TO FIX WRITE-PROTECTION PROBLEM: START > Run... > cmd
C:\> E:
E:\> attrib -r /S /D
----------------------------------------------------------------------------------------------------------------------------
PROBLEM 3: REGISTRY set incorrectly (targeted by virus or other malware)
HOW TO DISPLAY CURRENT SETTING: START > Run...> cmd
regedit
display HKEY_LOCAL_MACHINE\System\ CurrentControlSet\Control \StorageDevicePolicies

The valid values for this are 0=Disabled (meaning READ/WRITE), and 1=Enabled (READ only)
HOW TO FIX WRITE-PROTECTION PROBLEM: START > Run... > cmd
regedit
set HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\StorageDevicePolicies
to a value of 0 (Disabled)
----------------------------------------------------------------------------------------------------------------------------
A fourth way to "Fix" the write-protection problem would be to reFORMAT the flash drive, but
this "solution" merely resets the ATTRIB characteristic of the top-level directory of the
flash drive (while erasing all files on the flash drive), which is done better with the ATTRIB command,
and completely fails to address the possible write-protect switch or Registry issues.

I cant send any messages keeps saying hook uo to


Switch off your broadband connection for ten seconds and try to switch it back on. Go to control panel and click Internet connection as soon as wizard displays. Examine if the settings is enabled. Close the control panel and open run command and type cmd. After typing, when it prompts a command, type ipconfig and see if IP address and provider is listed with gateway and subnet. If it has all the addresses, so you can connect back to GMAIL. Thanks.
