Hi

I have a Panasonic TH-48LFE8E display in at the moment.

The standby (red) LED does not come on when the power is connected and the unit is not responsive to the remote control.
However when the power button is pressed on the set the green power on LED lights, but there is no backlight or other signs of activity on the LCD.
I have tried to obtain a service manual but apparently they are no longer available?
I have not repaired many Panasonic units and if any one can help it would be appreciated

I got a broken Panasonic that will not start. It does show the red front LED and the power supply delivers 5,3Volt standby. Only when you try to start by remote or push button on the set it will only flash the red LED and does nothing more.

After a while, the red LED will start to flash repeatedly 13 times.

Since the 5,3 Volt standby run straight to the main board I wanted to check there but no luck finding the schematics.

Any insights?

After several attempts the TV finally started and I could enter the menu screen. Normal functionality. But after switch off it takes again several attempts. What is going on ?

Sziasztok! Ma hozták ezt a tv-t, azzal a hibával hogy nem mindig kapcsol be. Bekapcsolva van amikor a piros led villog, de van amikor a zöld led villog, néha a kép is megjön pár másodpercig. A kezelő gombokra nem reagál, de a távirányítóra sem mindig. Szétszedve két tápfeszültséget tudtam mérni egy 6V, és 16V körüli feszültséget. Ezek a feszültségek elegek ehhez a készülékhez? Vagy frissíteni kéne a szoftverét?

Hello, I am working on a panasonic tv that shuts down a few seconds after it comes on, blinks(red standby light remains on)three times pauses, and repeat the cycle. Any ideas as to what could be wrong? Thanks.
