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 42PFL7403D (Q529.1ELA) nem indul (Error 2), és megoldása
Sziasztok! Rég jártam itt, de megosztanék egy tanulságos javítást. A fent nevezett lapost azzal hozták, hogy random kikapcsol. Szétszedtem, a tápon szépen látszott az invertertrafó lábának kimelegedése. Megforrasztottam és még egy csomó gyanús pontot, majd próba. A táp ciccen, aztán kiáll hibára, kettőt villogva a STBY LED. Na mondom f@sza, mit csesztem el? Táp ki, nagyítóval nem találok semmi cinpacnit és mégsem megy. Irány az internet, hátha. És lőn, egy külföldi oldalon egy bejegyzés, hogy kettes hibakóddal leáll, illetve el sem indul, ha szakadt, vagy kontakthibás a hangszóró ága. Mivel ennek a szutymadéknak a hátlapjában vannak a hangszórói és a hátlapcsavarok meghúzásával van kontakt, így természetesen nem voltak rajta a hangszórók. Összerakva kifogástalanul működik. Ha lett volna kéznél egy fejsze, biztos beleállítom.
