Re: Philips LED TV 40PUT6400/12 With Powerboard 715g6677
HI
yes i have checked all the pins, I get no DC voltage on any of this section of the board, all the diodes seem to be OK, fuses OK, rectifier seems ok (on a dead test).
I can do compoent testing but it takes time, hoping to just be pointed in the right direction of common faults on these boards if there were any
thanks

Philips LED TV 40PUT6400/12 With Powerboard 715g6677
Hi people.
got another TV i'm stuck with
Philips LED / LCD panel Model 40PUT6400 NO POWER OUTPUT
I have done all the basic testing, fuses, ac input / dc output etc.
I found no DC out to the main board, but I have never worked on a Philips TV before, and I'm not familiar with common faults on their boards.
Before I really rip into it, are there any common issues with philips TV power supplys?
thanks for your helpLast edited by loadedboyuk; 06-08-2020, 10:52 AM. -

Samsung UE55NU8770 TV Blink Error Codes
Hi everyone
I have TV Samsung UE55NU8770 Full Smart 4K
No Pic No Sound, No power up.
When I plug it in I Get a code flashing out on the stand by LED
1 Long / 3 Short
I can not find any service manuals or anything for this TV, and I have never seen a code on the newer models so I'm a little confused.
Before I get the back off I was hoping someone might have a clue to what is potentially the problem -

Re: Vestel / Luxor TV 50 inch UK Not reseting
this is driving me crazy, all the update and downgrades seem to work but even though the profile file says "HOTEL TV NO" when I boot the TV it says YES! and will not save the retune, or allow me to "reset" the TV from the TV tuning menu! a new board might be needed I thinkLeave a comment:

Re: Vestel / Luxor TV 50 inch UK Not reseting
Thanks for your help but it has not worked, TV is still acting in the same way
I added files to folder called profile, used the USB operations option in the service menu, when I retuned the TV and switched off it forgot all the channels again. it is not storing the changes I make.

Re: Vestel / Luxor TV 50 inch UK Not reseting
ALL SAYS OK
apart from DDR Settings that says NOK
I should also say, when I do a reset from either menu (service or retune) the TV looks like it will reset then goes to standby modeLeave a comment:

Vestel / Luxor TV 50 inch UK Not reseting
Hi people,
I have not posted in a while glad to see the forum is still going strong
I ahve a 50 inch luxor branded TV, it works well but it will not let me reset / return and store the updated TV channels.
it works fine while powered on BUT...
Every time I switch it off (stand by or mains) the channel lists reverts back to the old channel listings.
I have reset it multiple times, tried to reset via the engineers menu, ran to see if any updates are alavilbe over the internet.
its about 2 years old and "smart"... -
