Philips TV 43PUS6162/12 hiba és SSB kompatibilitás kérdés
Üdv!

Adott a fenti készülék Philips 43PUS6162/12 TV, TPM17.7E LA (2017) sorozat. Alig 4-5 hónapja járt le rajta a garancia, és egy pár napja azt csinálja hogy átlag 1 óra használat után ugrál a kép (minden forrásból, TV, Netflix, USB lejátszás, HDMI). Olyan mintha pár másodpercenként hibás frame-et olvasna. Rögtön bekapcsoláskor tökéletes és kb. 1 óra után elkezdenek megjelenni a képhibák előbb ritkábban majd egyre sűrűbben.

A kérdés hogy mi lehet a hibás fődarab, main SSB, T-com board, vagy esetleg maga a LCD panel (aminek nem örülnék)?

Ha a main board a hibás, előástam pár infot, a board típusa: 715G8709-M01-B00-005K
egy kicsit nehezen beszerezhető de van a ránézésre megegyező 715G8709-M0B-B01-005K ami az egy évvel újabb szériába (TPM18.6E LA) került. Mekkora eséllyel működhet ez ez én TV-mben?

Service manual szerint a 2018 board a következő 43" panelokat támogatja
TPT430U3-QVN03.U S0B0H
TPT430U3-QVN03.U S0B0W
TPT430U3-QVN03.U S0B0K
TPT430U3-QVN03.U S0B0K

A 2017-es a következőt:

TPT430U3-EQYSHM.G S1V
TPT430U3-EQYSHM.G S1AD
TPT430U3-QVN03.U S0B0F
TPT430U3-EQYSHM.G S1V
TPT430U3-EQYSHM.G S1V
TPT430U3-EQYSHM.G S1U
TPT430U3-EQYSHM.G S1AC
TPT430U3-EQYSHM.G S1U
TPT430U3-EQYSHM.G S1AC
Nekem a vastaggal jelölt van benne ami hasonló típus mint amit a 2018 tud. Működhet vajon?
 
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 !!!
