PJE mode problem

I cannot adjust picture in PJE mode. I am able to go to service mode, select GRN LIN, GRN PIN and other options, than when I move joystick up and down, the numbers in the upper right corner are changing, but the picture stays the same. I think, I may be doing something wrong, maybe the service mode is not enabled??? The only thing is working is the marker, I can move it around the screen, but the horizontal and vertical lines (crosshatch)are not moving. I have manual for this tv, and I follow the instruction, but for some reason picture stays bowed, and cannot adjust lines.

    the picture started to bow after I replaced STK chips. I sent board to Tri-state Module, so I assume board and chips are ok.

For normal convergence alignment you don't set the linearity or pincushion adjustments just the first alignments in the PJE menu. Your problem is most likely failed convergence output IC.s and possible fusable links (usually 3.15 amps that look like resistors) The IC's are most commonly STK392-150's if memory serves me correctly.

    Then possibly you have a bad "AD" board. it is a module that stands up vertically on the "A" board on the right side of the set. Try pulling it out by releasing the tabs and then reseating it.

My son set a privacy password and now cant remember it. how do i get in to reset password?


There is no way to recover a lost password without erasing the device.

First, turn your tablet off. Then, power the tablet back up by holding down the volume (either + or - ) and power buttons simultaneously. Continue holding the volume button until the screen says "Booting tablet in recovery mode." This will give you a picture of an Android. Tap the android, and you will be given a screen with several options. Move between the options with the + and -, and select with the power button.

Go to the option for Factory Data Reset and select it. Scroll down to Yes, and then the tablet will erase its memory back to factory settings. Once it has completed, select Reboot Tablet Normally.

Picture problem


This is something that can be adjusted from the service menu, to an extent. It's been referred to as the "football affect" as in severe cases your visible screen starts to look football shaped. Here's instructions on how to adjust it. It will take some playing with these settings to get it just right. OPERATION METHOD FOR COARSE ADJUSTMENT (first do it in NTSC Full mode) 1. Enter the service mode and select PJE category. 2. Press the 1 or 4 button on the remote commander to select the item, and then use the joystick to change the data 3. Press button 6 to display the internal test signal (crosshatch) 4. Select GRN CENT (or any item you want to adjust). When BLU or RED is displayed, press the 3 button on the remote commander to change the adjustment color in the order of GRN BLU RED. 5. In GRN, BLU, or RED mode, move the joystick up or down to change the data in vertical direction, or left or right to change the data in a horizontal direction. 6. Before returning to the service mode, press the MUTING + ENTER buttons on the remote commander to write the data. (You must complete step 6 to write the data. If you omit step 6 the set data is returned to the data prior to the adjustment. Like fine adjustment, data can be copied from NTSC Full mode to other modes. And re-register FLASH FOCUS is required for it to work properly (not overwrite your changes). Items available in PJE category for coarse adjustment CENT SKEW SIZE LIN MSIZ (horizontally only) MLIN (horizontally only) PIN KEY (vertically only) For each item (and each color), there are two numbers shown on the screen, one for horizontal data and one for vertical data. Write down those numbers before making any changes, in case you want to change them back. Ok, the things you need to adjust the football effect are pin, and key. Also you may have to work with the bow settings. Pin is what's pushing the corners towards the center of the screem. Bow affects the over all bend of the screen, and key is a wave type adjustment.

Why can't I adjust my color on Samsung Tv. I go into the menu and go to picture but it won't let me move up or down on the settings.


Do a hard reset to this set, and check thereafter. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

If the problem is with its picture linearity [Vertical], you have to enter its service mode to correct it. It is best to replace all the electrolytic capacitors [5 or 6] of it, at the vertical scan output circuit, before doing any adjustments, because, if there is any of it is damaged, the fault to this kind can occur too. After replacing it, just switch ON the set, and check the picture linearity is correct. If not, enter its service mode, and adjust the vertical picture linearity. If you wish to get some details, check the site linked here.Pull up older posts.

3. Select the PJE mode.
4. To automatically store the offset values, press the "FLASH FOCUS"
button on the front panel of the set.
(The offset value is now stored)

Convergence


Have you tried to adjust the convergence in service mode yet?
If not here are the steps.
1) Turn the TV off with the System off (under flap of remote)
2) Press: Display, 5, Volume+, then Power. If successful, service text will appear on the screen.
3) Use 2 & 5 - to select the PJE category. Be careful, like your computer, you don't want to be adjusting the wrong screen.
4) Press 9 - to get to the convergence adjusting.
5) Press 6 several times to get the convergence screen of choice. (I like the grid)
6) Use the remotes arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color(Push it sideways or up and down and hold). Press 3 to change color to adjust(red, green or blue). When done, press center of joystick again, this will turn it back to white.
Note: Try to keep the grid even and square.
7) Repeat step 6 for all parts of the screen that need it.
8) Once done, you need to save your settings. Press: Mute,Enter. Then on the T.V. press "Flash Focus" (it will set it self)
9) Turn off Power.
