Hi,

With the indulgence of Drummernick and coolguy008,

May I offer a brute force remedy?

Individually adjust the screen and focus controls of the the three FBTs. You probably have to wing it and adjust to best possible setting.

This is of course assuming no hardware fault but the unit has been in operation for some time and there are no other remedies available.

Good luck and kind regards.

    Hi again,

    Appreciate the point out.

    The FBTs are inside the cabinet. As standard extreme care when adjusting internal of live sets. The screen and focus controls are married to the rear end of the flyback transformers. It would be a good idea to use a mirror while adjusting to show the screen front. There are no specific guidelines since one who is adjusting can see if the adjustment would be ok or not by looking at the displayed images.

    Should you be uncomfortable going through these route or unfamiliar with electroni circuitry and compnents, then perhaps the suggestion of coolguy008 is your best bet and seek the services of a qualified professional.

    Cheers.

    BTW,

    Adjusting the screen and focus controls is more of a "tweak" rather than a "fix", it is squeezing a few more out of your system before due replacement.

It is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels.

I am further looking into ur problem..

Goodluck..

    Do you observe any strange colours like red or rainbow in between the screen??

  • Priya darshan Feb 07, 2008

    No there is nothing like that.You have to get it repaired by a technician and thats the only solution..

  • Priya darshan Feb 07, 2008

    Alright give this a try:

    do the reset test. I give this a 50/50 chance of
    clearing it up. Disconnect the power cord for 4 hours. Then when you
    power it back up
    the internal soft codes will automatically reset to factory defaults.

  • Priya darshan Feb 07, 2008

    Dude i never said it is a right remedy and anyways u have to get it repaired by a tech even if it is the bulb problem..

  • Priya darshan Feb 07, 2008

    I also want you to have a look at this once but they charge you for this:

    http://fixyourowntv.com/servicemenu.php

  • Priya darshan Feb 07, 2008

    Ya dude i know that we have told her all the possible ways to get it fix and what if he/she can't solve the problem by self then u have to call a technician as the problem can also be inside the TV.

  • Priya darshan Feb 07, 2008

    Please follow whatever i said and if nothing works out call a technician and get it repaired fully so that you don't face any other problems in future..


    And thanx for agreeing wid my solution Benimur

Fx 115 es can't see the display


First, try adjusting the display contrast. Press SHIFT MODE down-arrow 6 then use the left/right-arrows to change the contrast. If that doesn't do any good, try replacing the battery.
Contrast adjustment is on page E-5 and the battery replacement instructions start on page E-71 of the manual.

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.

Hello

It is not the code problem. There is only one code, and it is for adjusting its parameters , and have beed done at the factory, and havenot, and should not be changed at all. You just inform them to check its chroma section, with its schematic dagram nearby him, whether the colour and contrast pin control voltage of the chroma IC is vaiying according to the increase or decrese to the parameters with its remote or with its fron panel control. If it does not varies, tell him to check its system control side. OK

Need to change tint, color on screen using the remote of course


Since you do not provide the make and model number of the TV so we can look for the user manual for you to read on how to make adjustment to your TV.
You just have to get to the MENU button on the remote for the ON screen setup menu and look for Picture adjustment set up to adjust the Pictures.
It should show Brightness, Contrast, Tint, Color adjustment choices.

Hope you have adjusted with your remote. Even with this if the problem repeats, there may be resistor gone in high value or open.

Try the circuit associated to red gun ( cathode of the picture tube). If you have a digital meter, switch OFF TV and give a check on all the resistors. Check whether any value is changed to higher side.
If you notice any ohmic value changes replace them with identical type.

If variable potentiometers are provided try adjusting them. But note down the orginal position.

If it is service mode adjustment, contact SONY service center as the service pass word code is known to them only.

Hello Paul. I have this same monitor, but rebranded, Access the service menu with the remote control:

With user’s RC
1. Power TV On
2. Press Menu button and call up User OSD Menu
3. Select Sound-> Balance
4. When Balance value is “0”,Enter 0->5->3 ->2 in sequence.
Note: If necessary, re-do number keys.
5. Factory OSD appears.
6. Press the standby button then AC turn off and restart the TV, which can exit factory

Display problem


the adjustment box for colour, brightness and contrast stays fixed on the screen. i tried pressing the exit button.... after a few times it disappears only to reappear within a few minutes. also the auto adjustment option, for which we are supposed to manually press the i button, keeps auto adjusting the screen whenever it feels like it. the box appears right in middle of the screen and is a real nuisance as it blocks out the main portion.
