Sziasztok! Tolmácsolnám egy ismerősöm gondját :) Hátha tudtok segíteni:) "Tárgybeli tv-ben áthúzott a sortrafó. Csere után indult, majd leállt azonnal. A sortranzisztor kollektorán kb. 600V-s impulzusok jelentek csak meg. A tápban kicseréltem az SE130N ref. ic-t, ezután nem kapcsolt ki, képeltérítés is működött az eltérítő tekercsből jövő jellegzetes hang alapján, mivel képet nem láttam, mert a g2 teljesen le volt tekerve. A következő indításkor ismét letiltott. Kiderült, hogy megfut a táp. Természetesen az új se130n miatt. Csere után táp rendben, sor megy, képeltérítés semmi. Mérés alapján, nincs meghajtás. EEPROM csere, függ ic csere, diodák ellenőrizve, tápok jók. Kb. 2 cm eltérítés van, zaj nélkül, csak tejföl. A DDP3315C ic-ből kellene kijönni a vezérlésnek meg a képjel is ebben ic-ben kerül feldolgozásra. Találkozott már valaki ilyen hibával, amit ez az ic okozott? Vagy esetleg valamit még nem ellenőriztem? Egy biztos eeprom tartalmat még belepróbálnék. A procin 030.12SP verzio szam van. Ha valakinek van tapasztalata, jól jönne a segítsége." Üdv: Pityesz
Panasonic TX-32PS12P CP830FP időnként újraindít, kép eltűnik, hang, sor tovább megy
Üdv Mindenkinek! Fent nevezett ezt produkálja. Újraindításnál rugdossa a demag relét, miközben a sor él, hang van. Képcsőt mérve: R 0,6, B 0,7, G 0,75. Csöve:W76MAF 185X72. Tápok rendbe, (mind a prim mind a szek). Függ. cserélve, imp kondik szintén. Mégis a képcső? Köszönettel.
Panasonic TH-48LFE8E LCD Display No standby LED but power on LED and no display?
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

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
 
Stephen Fry
