Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
Thanks , I've been searching allover and all that I can find is foreignforum pages and no schematics, anyway I'm using a new Samsung led now but I may try swapping the psu at some stage in the next few weeks.
If I find a fix ill update the thread then.
Thanks to all who have helped to find a solution anyway .
All the best ....

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
So does this seem to indicate the psu is faulty as its not supplying voltages correctly to the connector that goes to the logic board?
obviously i am new to this but it seems to me some components have shorted/failed in the circuit from AC power in to the output socket that goes to the main board.
Im thinking of replacing the psu completely if this seems to be the board that has failed .

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
Thanks alot Marty!
Edited to ask : To measure the caps pins would it be ok to take the psu out of the chassis and have it plugged in on its own with nothing else connected to measure the voltage ?
Should i be measuring the caps for volts or Ohms? Thanks again
So this is the 11 pin Connector first , strange
+7.5v raising to around +7.8v
+7.2v raising to around +7.8v
0v

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
Hi again vince i have looked but no there is not any markings for voltages , I really need to find out what they should be but cant find a diagram.
Ive been testing the caps on the PSU and the results i have marked on the following picture .

Does this seem abnormal readings ?
Thanks alot in advance in the meantime im going to take the readings of the caps on the mainboard.

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
I have that .pdf already and looked through it but i dont have a clue which part is which and i cant seem to find any diagrams explaining which points should be certain volts.
Its hard to understand it to be honest....Leave a comment:

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
I know what you mean on the not much info on the 2 blinks , Ive searched for ages but there is only a handful of threads i can find that seem to have the same problem .
I have taken a picture of the underside of the board as you mentioned but unfortunately no markings or anything .

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
Thank you for the advice vince!
I have included some more pictures of the connectors and board. The first picture is one i found on google images at a better quality resolution as my camera is poor.
ive noted where the AC power connects to the PSU and where the cables leave the PSU and go to the logic board .

Thank you for the reply
Unfortunately the board near the connector does not show the voltages printed on the board. I will try to get a clear picture of the connector and report back asap.

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
I found the only available logic board for this tv on ebay . If i knew it was definitely this that was malfunctioning i would order it but i dont fancy spending money if it will not solve the problem . Is there any cheaper places to buy parts for this model or are they pretty much unheard of now?

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
OK , First sorry for all the double posts i should of taken my time and just posted once.
So, I have inspected every cap on the power supply and all of them have current running through them .
I inspected all the caps on the main board and all of them are them have current running through apart from one which shows 0 M OHMS.
I have pointed out in the included pictures which capacitor is displaying 0 value at all.

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
i had it on the wrong setting so its at 246.2 v at the mains so is that about right for UK ?
Where do i start testing from here ? a little basic guide for what components are important to test first on the board would be great , Thanks in advanceLast edited by rigby; 02-10-2016, 06:56 AM.Leave a comment:

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
Thank you vince , I forgot to mention i upgraded the firmware with the newest available on the philips website a couple months prior to this issue . Wonder if that may of caused it or maybe the age of the set as it is quite old but i would love to find a fix for it .

Re: PHILIPS (42PFL7623D/10) 2 BLINKING RED LED's
Thanks i located it by searching the q529.1E la service manual , im looking through the .pdf .
I cant see any chart that indicates what the led flashes mean. I must admit although i am ok at soldering im not too clued up on what different parts of electronics codes and names mean .
If , say i just ordered a new power supply board for the set instead of locating certain caps on the board to replace , and installed would that be an ideal thing to try first ?...Leave a comment:

I cant see any chassis number on the sticker . Thanks again for the help
