Panasonic TX-32pm11d shutting down
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.
Panasonic TH-65LFE7E shuts down after few seconds standby led blinks on a 5 second interval.
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

Panasonic TH-37PX8ES negatív képe van
Sziasztok! A fenti plazma tvnek negatív képe van.Az OSD jó.Ha AV-n nézem egy kicsit kontrasztosabb képe van de nem tökéletes.Nem volt valakinek ilyen hibája?Kép mellékelve
Panasonic plazma Y-sus javítás / GT30F131 -igbt-t keresek hozzá - Megoldva!
Sziasztok! Hoztak javításra egy 3D-s plazma tv-t. Típusa: Panasonic TX-P50GT30J. Az Y-sus panelen zárlatos 3db-n csatornás és 3db p csatornás IGBT. Ezzel sikeresen zárlatban tartja a tápot. Az IGBT-k típusa:GT30F131 és RJP30H2A, összesen majdnem 5000 Ft az ára. A tv bőven megéri, de ha valakinek van tapasztalata hogy mit kellene átméregetni hogy ne süsse meg újra az első bekapcsoláskor, az kérem segítsen ki egy kicsit. Biztosan van valami klasszikus oka ezeknek a hibáknak,csak rutin nélkül nem tudom mit keressek. Eddig jobban csak LCD és CRT tv-ket javítottam, a plazmákat csak nagy vonalakban ismerem. Lehúzott csatlakozóval a táp megy, érdekes módon a készenléti 5V-ot előállító step-down konverter nem működik így a 13V-ból 7805-el kellett kipótolnom ideiglenesen. Persze erre még visszatérek ha a többi része működik. Rajzot csak a TC-P50GT30A -ról találtam, (itt a tanyán)de ezzel úgy nézem nem egyezik. Előre is köszönöm!
