Hi
I am having trouble finding any information regarding this product.
The unit powers up and the output is displayed on the screen for between 0 and ten seconds, the unit then powers down, the red standby LED on the front of the unit blinks then remains off for 5 seconds then blinks again.
This cycle continues until the power is disconnected, if the power is reconnected the unit goes back in to stand by (red led steady) it will then power on again.
Also in the error mode (red led blinking) and the power button on the back of the unit is pressed twice it will power up but this does not happen if the remote is used.
I have tested various capacitors and diodes but all seems well, I have also replaced the power supply with a reconditioned unit but this has not helped.
I have been unable to obtain any service information for this product.
So any input would be most helpful.
Thank you
Stephen Fry

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 ?

Van valakinek elado alaplap (Mainboard) LCD Panasonic TXL26C10E.
A fenti masinával lenne egy kis gond.
A tulaj elmondása szerint tökéletesen működött, mind addig amíg d-sub kábelt nem dugtak rá. Ezután jött a probléma. Bekapcsolást követően éles sípolás jön a hangszórókból. A probléma minden bemeneten jelentkezik. Filmeknél a robbanások hangja helyett csat recsegés van, szövegnél lehet hallani mit mondanak, de a sípolást is. Szétszedve a masinát a következőre jutottam: sehol semmi probléma. Az audió IC-t könnyű volt megtalálni. A száma: D5452A. Erősítsétek meg, hogy ez szált el.
