Sziasztok!
Megtaláltak ezzel a tv-vel. Jó nagy, így nem bánnám ha nem lenne láb alatt... Zöld - narancs színben villog ha bekapcsolom, hátteret és t-con tápját nem próbálja indítani egy pillanatra sem. Vagy fél óra villogás után kikapcsol, led sötét. Ha visszakapcsolom, kezdi elölről.
Az USB frissítés nem meg le rajta, egy idő után átvált lassú fehér villogásra - de ezzel sem végez órák alatt sem.
A dump megvan, és az emmc csatlakozási pontok is.
Viszont nem igazán tudom hogy kell ezt a 7 fájlt hogyan kell beírni - illetve hogy kell beállítani az RT809h szoftverében.
Van 3 db dump, egy 15Gb és két 4 Gb körüli. És még van 3 db extcsd kiterjesztésű fájl is.
Az LG -nél csak a nagy dumpot írtam be (azonosítók cseréje után), és kész. Ez valami bonyolultabb.
Ebben kérem a segítségeteket, egy részletesebb leírást keresek az író szoftver beállításáról.
Azt írják hogy a Netflix kivételével minden működni szokott.
Köszi!

Sziasztok
Fent említett LCD a csatolmányban lévő képet produkálja monitorként is, meg tv-ként is, azaz dupla képet, felső negyedben érdekes mód jó a kép. Elmondás szerint a gyermek belefejelt a kijelzőbe elég keményen, azóta van ez a helyzet. LTY320HM01 A05 kijelző lakozik benne, ez ment volna tönkre, esetleg javítható-e? Vagy máshol keresgéljem a baj forrását?
Válaszaitokat megköszönve: Csaba
Hello
I have on my table this sony kdl32ex600 with backlight issue. It's a common failure of this psu but i do not find any part faulted on this board.
The schematic it is almost the same, with minor differences with GE3B found at page 56 on this service manual:
https://elektrotanya.com/sony_kdl-32ex600_kdl-40ex600_kdl46ex600_chassis_az1-k.pdf/download.html
Uploaded only the page 56 from this sm to easing the search.
The red led it's flashing 2 times, meaning psu faulty. Indeed the led backlight does not light.
With the PSU outside of the tv, just with one resistance of 180ohm between standby ( pin 1 3,3V on connector CN6150 ) i get this values
on in:
starting with pin 1
1 +3,3V ST-BY
2 +3,3V AC_OFF_DET
3 +3,3V POWER_ON (with resistance 180ohm between pin1 and pin 3)
4 +12,56V AUDIO_12V
5 0V AUDIO_12V_GND
6 0V REG_12V_GND
7 0V REG_12V_GND
8 +12,6V REG_12V
9 +12,6V REG_12V
10 +0,1V BL_ERR
11 +3,3V BL_ON
12 0V DIMMER
13 0V DIMMER_DC
14 0V T-CON_Vcc_12V
15 0V T-CON_ON
All measure done at secondary ground point C6800 GND as reference.
Meanwhile, the led connected to CN6800 will remain with no light at all. The CN6800 will deliver positive 91V.
The negative branch will deliver at CN6801 ( both pin1 & 2 ) just -1V.
In the training manual found always in here at
https://elektrotanya.com/sony_kdl-32ex600_40ex600_46ex600_chassis_az1k_training%20manual.pdf/download.html
at page 56 will say "SHORT" at pin 12 DIMMER for testing the PSU, always with pin 3 POWER_ON connected to 3,3V ST-BY - pin1.
If i'll put a 180ohm resistance between GND and pin 12 DIMMER, then the tension on CN6800 will rise to +179V and the negative from the CN6801 will rise to -5V, the backlight led will light very very weak.
All tension from CN6805 will remain the same, except the BL_ERR will rise from +0,1V to +1,1V.
With only power_on pin 3 shorted by 180ohm resistance to the pin 1, i get this weak oscillation at emiter of Q6816 + Q6817

With pin 12 DIMMER shorted ( always by a 180ohm resistance ) at GND, the oscillation will change from 250khz 1,6vpp to almost 70khz at 0,81Vpp. as below:
[URL=https://picturepush.com/public/16067401][IMG]https://www1.picturepush.com/photo/a/16067401/640/diverse/20181117-175255.jpg[/IMG][/URL]
Already checked the capacitors C6828 / C6830 together with D6805 / D6806.
Also checked the L6800 ( trafo ) and i've get 5,5mH instead of 5mH, i think it's ok.
All fuse checked, ok.
Q6814 and Q6801 tested under mosfet tester, ok.
[url=https://picturepush.com/public/16067402][img=https://www1.picturepush.com/photo/a/16067402/220/16067402.jpg][/url]
IC6800 & IC6801 gave +9V and respectively +2,49V
Already checked various components all over the board, i am out of ideas.
Any idea or help would be apreciated.
