LC-40LE830E lampeggia led

[giurgin]

Buongiorno a tutti

Ho in laboratorio questo tv che ha il led che lampeggia lentamente una volta ogni secondo e mezzo circa

Dal SM si evince che è il solito errore led

Ho provato a resettare il tv ma quest'ultimo non è dotato di pulsantini ma di una tastiera touch e la procedura non funziona...

Qualcuno ha la bacchetta magica? Sapete dirmi come si resetta l'errore o se sbaglio io? io premo Vol - e input e quindi do corrente....

grazie in anticipo!

mi sembra non sia quella la procedura completa

è quella che ho letto scritta da Fulvio in prima pagina....

forse la memoria mi tradisce,comunque sul manuale di servizio c'è riportata.

 

 

3. Entering and exiting the adjustment process mode
Please execute the following procedures to enter the adjustment process mode when the power supply shuts down.
1) While holding down the “VOL (-)” and “INPUT” keys on the set at once, touch the power supply key on the set.
Please separate the fingers from key on the set when boot-up is confirmed with lighting of a central icon etc.
After a while, The letter “K” appears on the screen. This state is in Inspection mode.
2) Next, hold down the “VOL (-)” and “CH ( )” keys on the set at once.
Multiple lines of blue characters appearing on the screen indicate that the set is now in the adjustment Process mode.
If you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
3) To exit the adjustment process mode after the adjustment is done, unplug the AC power cord to force off the power.
(When the power is turned off with the remote controler, once unplug the AC power cord and plug it in again. In this case, wait for 10 seconds or
so after unplugging.)

 

8. Lamp Error detection
1. Function
This LCD colour TV set incorporates a Lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp
circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason,
the following will result.
1) The power is interrupted in about 500ms after it is turned on.
(A central icon on the front of the TV flash on and off.: ON for 400ms and OFF for 1600ms.).
2) If the above phenomenon 1) occurs 5 times, it becomes impossible to turn on the power.
(A central icon keep flashing on/off.)
2. Measures
1) Set the lamp error detection to OFF
Enter the adjustment process mode, referring to “4. Entering and exiting the adjustment process mode.”
The adjustment process mode can ignore “5 times count”, so If the above phenomenon 1) occurs 1~4 times, the lamp will go out.
If Lamp Error detection pin (6pin of LB: P9602) is “High” by a trouble with the lamp and lamp circuit, it can boot-up by the adjustment process
mode.
Please execute “Lamp Error detection off-mode”.
While holding down the “VOL (-)” and “CH ( )” keys on the set at once, touch the power supply key on the set.
After a central icon flash off, separate the fingers from key on the set.
Touch the power supply key on the set again, so the power will boot-up.
Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
If you fail boot-up, retry the procedure.
2) Resetting the lamp error count
After the lamp and lamp circuit are improved from a trouble, reset the lamp error count.
(Because the power cannot be turned on, if a lamp error is detected 5 consecutive times)
a) Enter the adjustment process mode, referring to “4. Entering and exiting the adjustment process mode.”
Using the cursor ( / ) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/21.
c) With the cursor ( / ) keys, select the [LAMP ERROR RESET] value.
Finally press the cursor (OK)., the count is reset.
Check LAMP ERROR Count on adjustment process mode Page 2/21.
