Re: Polaroid P40LED13 powers up then shuts down

Your mb is at fault still, you need to heat it up and see if it shuts off faster.

Freeze spray U46 common fault on thse see if it stays on longer.

Re: Polaroid P40LED13 powers up then shuts down

spent far too much time now warming boards and components nothing seems to make it shut down, just seems to do it when it feels like it sometimes 10 - 15 mins sometimes 30 -45 mins between shut downs. I have noticed though it seems to start back up pretty quick certainly a lot quicker than a normal power up from switched off.
Is it possible I have installed the wrong core update, or would it just not start with wrong update.
May try and source a used mainboard and put that in

Did you download the Vestel Driver 17mb82-2 ? Also got image of the menu system ? Also dont give up yet I wouldn't, if you do I have a board for this set for £20.

Re: Polaroid P40LED13 powers up then shuts down

think update i got off vesteldriver.com was 17mb80*** awkward as all in turkish, I think it is still a software fault on this tv
mainboard number is 23115995 23115994
do you want a picture of menu if so which page of menu
may well have the board off you if it will sort this tv

Re: Polaroid P40LED13 powers up then shuts down

Just the menu in general. Also link I use:

[london-freddie]

Re: Polaroid P40LED13 powers up then shuts down

Yes that is the link that i used to download from MB82 V.0.84
just powered up the tv again to take pics of menu, while taking them tv switched off about 6 times different colours on screen each time red, green, pink etc
will download pics in a few minutes

Re: Polaroid P40LED13 powers up then shuts down

Thats really odd, at this point Im unsure whats causing it to crash like this mate with out having it in front of me Will have a check on the web and let you know if I find anything got to be firmware related unless you missed something obvious. I presume you left the Usb in till the set came back on too ?

Re: Polaroid P40LED13 powers up then shuts down

update!!!! replaced mainboard tv now been working fine for nearly a week now, thanks again all

Re: Polaroid P40LED13 powers up then shuts down

Good work

Re: Polaroid P40LED13 powers up then shuts down

I, too, have this same issue. Used air can on chips but tv turns on then back off. Are you saying this is a MB and not a power board issue?

Re: Polaroid P40LED13 powers up then shuts down

Corrupted F/W on mainboard causes this fault. on the MB82 Vestel...

[speedypro]

Re: Polaroid P40LED13 powers up then shuts down

I have downloaded the firmware, in this thread, and it updated. Once the tv finish updated the tv powers on but instantly shuts off. Same as before.

Re: Polaroid P40LED13 powers up then shuts down

Update. Nothing to do with F/W. Ive remove the led red/black wire from psu and shine a light on tv and I can see images so led driver fail. What to replace?

Charles Hyde do an USB stick firmware update

LED issue, not F/W. Works if backlight wire removed from psu

Re: Polaroid P40LED13 powers up then shuts down

probably a shorted led time to strip down and test them i guess

Yup! I will decline. Last time I cracked the screen! It's sooo.....thin. I'll tell the customer I can repair it.

[vinceroger69]

Re: Polaroid P40LED13 powers up then shuts down

yes that whats bothers me with customers sets too be honest if it was my own i would try the repair, the last 40 in set i repaired i used some think lining wallaper and slid it slowly under the lcd glass then gripped both sides of the lining paper and lifted the lcd up (so acted like a support i guess) it worked ok plus no finger prints on lcd/diffusers.I do find putting the plastic lcd surround back on the hardest thats how i cracked one.
