Question about Televison & Video

1 Answer

Service Remote Hi. I was going through the service menu on my 44sz8r tv and changed an option by accident and now my remote control doesn't work. The option said something like "CHREM=0" and changed it to "CHREM=1" then the menu came off before I could change it back. As I needed the remote to get into the menu in the first place, i'm just wondering if is there a way to reset the service settings or get in to the menu WITHOUT the remote? or have I had it. I've just read your post about the service remote you got and was wondering if it connects to the back of the set via a Pc serial cable or if it just works by itself. My set is the LG 44SZ8R. Hope you can help. Thanks.

    Hi.

    I knew that you wasn't a "problem solver" but i figured you might be able to help. thanks for the reply anyway.

    I've just got a reply back from lg UK and they too are saying that I need to purchase a new remote from a partner company. I'll probably find that it's the same remote that you had to buy.

    Are you saying that because it hasn't got instructions you still can't get into the service menu? i hope not.

    Thanks again.

    Hi.

    I'm not an engineer but i managed to reset my lg 44sz8r lamp
    timer by pressing (and hold) MENU on the set & then press and hold
    MUTE on the remote.

    The lamp reset menu should pop up allowing you to choose reset.

    Good Luck.

    I can't get my light timer to reset. I press and hold menu on the TV and press and hold mute on the remote. I can't get the time reset to show. How long do you have to hold down the button and do you have to have a special remot to do this. I have a LG RU-44sz51d TV

Sorry, I'm not a problem solver. I had ask a question myself several month's ago that went unanswered. My tv is a LG RU44SZ63D. Through my own diligence I discovered that the special set-up remote for accessing the service menu is a 105-201M. I have no idea how many different model tv's this remote works on. I purchased the remote from www.newremotecontrols.com. It "IS" a tool and unfortunately doesn't come with instructions...

    There's a button on the remote labeled IN-START. Pressing this button brings up the service menu then you navigate using the left/right/up/down buttons and close the menu by pressing the IN-STOP button. There's a whole bunch of other buttons that don't have anything to do with "normal" tv operation. That's where an instruction manual would come in handy. I intend to use my remote for only one purpose, which is to reset the lamp timer the next time I have to replace the lamp.

Press the helpful button and check link below for various models

It'll show the hidden service menu on your TV screen.
Once you enter into service menu, you can press Menu (or Options) button again on your remote to switch between various service modes such as Digital, Chassis and VPC.
To navigate between available options press 1 or 4 buttons. To change or modify their values press 3 or 6 buttons.
To save your changes, just press Mute + 0 (or Enter) buttons on the remote.
To restore settings to factory defaults, press 8 + 0 (or Enter) buttons.

Tip

Service menu codes panasonic


I provide this information for those that are qualified and trained to do TV repair work. Entering or making changes in service mode by untrained persons can cause significant and permanent damage to your television. If you are not qualified to service your television, please DO NOT ENTER these service menu codes.

Panasonic TV's after 1996 can be set to "Serviceman Mode" with the
following remote control sequence:

-select the SET-UP icon and select CABLE mode.
-select the TIMER icon and set the SLEEP timer for 30 minutes.
-press the ACTION button twice to get out of the menus.
-change to channel 124.
-adjust the volume to minimum (0).
-Hit the VOL down button on the TV itself (not on
the remote) and a red "CHK" should appear in the upper corner.
-press the ACTION and VOLUME DOWN buttons (again, on the
TV, not the remote) you will toggle between AGING and SERVICEMAN modes.

Select Serviceman mode. The POWER button on the remote control will
select one of the five Serviceman Adjustment modes.

The modes are:

B - Serviceman VCJ SUB Adjustments. These include sub-tint,
sub-color, sub-brightness, sub-contrast, colorkiller/ABL/gamma,
audio and video adjustment, and vertical size.

C - Serviceman VCJ Cut-off adjustments. These include Red, Green
and Blue cut-off, red and blue drive, automatic fine tuning
(AFT), RF AGC (RF gain control), horizontal center, beam limit,
etc.

S - Serviceman Options Adjustments. These involce the PIP and
clock.

M - Serviceman MTS (Stereo/SAP) adjustments.

CHK - the mode you first entered. Normal picture and sound, lets
you check things over and still have a hotkey into the
service menu.

There is one more adjustment that isn't in the five modes, it's
global. When in either the yellow or red CHK mode, you can press
RECALL on the remote control to enter the purity field check mode.
This lets you select a pure white, red, green, or blue screen. A
good thing to walk away from if you just want to temporarily freak
out the floor manager, but it will be fixed as soon as the TV is
turned off. Oh well.

To get out of Serviceman mode, press ACTION and POWER on the
receiver simultaneously for at least 2 seconds. The TV will momentarily
shut off and then comes back on.

I have a 42inch sharp aquos LCD tv and there is no power. The power button keeps blinking. There is no picture and sound. What is the fix to this problem.


Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

You need the factory remote only for this model of set!

Contact the service rep for your set and order a new remote.

As for the service mode, most RCA sets require an external service interface.

In many models of sets, the results and commands are in HEX. You will need the service manuals, hardware interface, and instrumentation to do proper setups and adjustments.

As for accuracy of adjustments, from factory these sets were very accurate. If there are changes, this is due to failing parts, and not from adjustments going out. The setups are all uPC controled and are exact. The set should be serviced to make it work properly, and not adjusted to offset faults.
