REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

SHARP LC-40LE810UN - LC46LE810UN - LC52LE810UN - LC60LE810UN – HOW TO ENTER SERVICE MODE – LED BLINKING CODES – ERROR DISPLAY CODES AND DETAILS

SHARP LC-40LE810UN - LC46LE810UN - LC52LE810UN - LC60LE810UN – HOW TO ENTER SERVICE MODE – LED BLINKING CODES – ERROR DISPLAY CODES and DETAILS

Error Display details – LED blinking code details – Service Mode – Hotel mode – SHARP LC-40/46/52/60LE810UN LCD Televisions
When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed.  This is not a malfunction, and the unit will recover when the temperature returns to normal.
Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a heater, as this may cause the cabinet to deform and the Liquid Crystal panel to malfunction.  Storage temperature:-4°F to + 140°F (-20°C to + 60°C)
ENTERING AND EXITING THE SERVICE MODE 
1 Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.
2 At the state TV is turned on, touch the power key for 5seconds.  NOTE: Picture will disappear when you touch the power key, but keep touching the power key.
3 When the center icon LED blinks, release your finger from the power key.
4 Next, touch the power key with “VOL (-)” and “INPUT” keys at the same time.  TV will turn on and the letter “<K>” appears on the screen.
5 Next, touch the “VOL (—)” and “CH (▼)” keys at the same time.
6 When the center icon LED turns on, release your finger form the keys.  (The “VOL (—)” and “CH (▼)” keys should be pressed and held until the display appears.)
Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.  When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
7 To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)
CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the settings are tampered in this mode, unrecoverable system damage may result.
Remote controller key operation and description of display in adjustment process mode
Input mode is switched automatically when relevant adjustment is started so far as the necessary input signal is available.
PUBLIC MODE SETTINGS
There are the following 3 ways to get the public mode setup screen displayed.
In the adjustment process mode, turn on “PUBLIC MODE”
1 Plug AC cord and turn on the TV.
2 After picture displayed, touch the “POWER” key for 5seconds. NOTE: Picture will disappear when you touch the power key, but keep touching it.
3 When the center icon LED blinks, release your finger from the power key.
4 Next, touch the “CH ( )” key and “VOL (+)” keys on the set at the same time.
5 When the center icon LED turns on, release your finger form the keys. It’s same as from 1) to 3)
4 Next, touch the “INPUT” key and “CH ” keys on the set at the same time.
5 When the center icon LED turns on, release your finger form the keys.
6 Get the password input screen displayed.
7 The 3-digit password is now verified.
The password [0] [2] [7] provides for the public mode screen. (This screen comes on with whatever adjustment process settings.)
With any other passwords, the screen changes to the normal mode.
Procedure
The input starts with the leftmost digit.
Use the numeric keys [1] thru [9] and [0] keys on the remote controller.
The other keys are not acceptable.
With a numeric-key input, "_" will change to "*".
The input position will move one digit to the right.
With all the 3 digits entered, the password will be verified.
HOW TO EXIT THE PUBLIC MODE
There are the following ways to quit the public mode setup screen.
Turn off “PUBLIC MODE” in the adjustment process mode. (*) ß This way alone is not for quitting the setup screen, but for quitting the mode itself.
Turn off the power with the “POWER” key. (*)
Select “EXECUTE”. (*)
(*) “PUBLIC MODE” stays on in the adjustment process mode.
(*) The settings will be back to the factory ones.
PUBLIC MODE SETTING VALUES
With the factory settings made, the public mode settings get initialized. (The adjustment process remains intact.)
PUBLIC MODE MENU
The guidance is not displayed on screen.
Setup procedure
> To move the cursor up and down, use the “cursor UP/DOWN” key (remote controller) and “CH▲/▼ ” key (remote controller and set).
> To change the settings, use the “cursor RIGHT/LEFT” key (remote controller) and “VOL (+)/(–)” key (remote controller and set).
> To save new settings, keep the cursor at “EXECUTE” and use “ENTER” key (remote controller and set).
