Philips 50PFL7956k/02 3-at villog, távra nem reagál

Sziasztok!

Kerestek a fenti TV-vel, áram alá helyezve 3-at villog ütemesen. 3,3V készenlét megvan, előlapi gombokra pittyeg, de nem kapcsol be, távra nem reagál.
A táp át lett méregetve, zárlat nem található benne, szemre is jól néz ki, elkók nem puposak.
Van valakinek tapasztalata vele?

Üdv: Jácint

Philips 40PFL7007K/12 does not power on - Chassis QFU1.1E LA
Hi everybody, I have Philips 40PFL7007K/12 on repair. TV does not start up. I have checked the PSU and it seams to be OK. There seam to be problem on the main board. What I have tried… Well, there is +3V3-STANDBY coming from PSU to main board. This feeds up the main processor. This voltage has also been used to switch TV on. I have checked that switching signal from POWER ON button goes back to main board. But I did not check this whole path towards the processor as it is BGA package and it is covered by ceramic cooling plate. And here comes what is not clear to me. 1. How to check if the main processor works? Does it work on the +3V3-STANDBY when TV is is standby mode? 2. Can I somehow check if the PSU is working? May be by activating some pin? 3. I have noticed by measuring (ohm-meter) some capacitors on the main board (in circles on the picture) that there is very low resistance on them (4.5ohms). In the scheme it is shown that these capacitors are on the 1V5 (1.5V) line. Is this OK? Basically it does not give much current as I = 1V5 / 4R5 = 333mAmps. What do you think? Certainly there are low voltage data parts (RAM. Processor …) connected and such resistivity might be correct….?.... What I have also find that this 1V5 is split into 1V5M0 and 1V5M1. See the picture. I have removed the coils and measured resistance. Then 1V5M0 shows about 15ohms and 1V5M1 shows about 6,5ohms.

PHILIPS 55PUS7809 power up but no image, screeen staying black
Hi everyone,

I'm trying to repair a philips 55PUS7809 with power but no picture.

After disassemblying it, I found out that a Q3 transistor had blown away on the T-Con board réf. 6870C-0502B (LG Display)

Anyone could help me finding the diagram of this board?


Thanks a lot.

04/07/2019 : I ordered the board on aliexpress.com

10 days after, I received a refurbished board with one inductor case broken. Also I had to pick up a LVDS lever from the old board to replace one missing 
on the new board.

After plugin everything back, Tv is working again !!

Bought 1400€ 5 years ago, I'm happy to fix it with only 8€ (shipment included)

THanks Aliexpress !!!

Sziasztok! Elakadtam ezzel a géppel sasszi AA5AB, alaphiba nem indul a sor csak a led villog mindössze egy kattanást lehet hallani és egy ugrást lehet látni a TDA8362 H outján,és a sormeghajtó primerjén a tranzisztor bázisán már semmi nincs, amit cseréltem eddig: sorkimenő, sorvégtranzisztor,TDA8362 61-re sormeghajtó tranzisztor, eredmény nem változott. Valamit elnézek ugyérzem ebben kérném a segítségeteket.
