Re: Hisense Plasma PDP4235EU

Im trying to take the Y Buffer board out, but the ribbon cables dosn't come out,

i opened the latch who secure the ribbon cable, and tried to pulled it out,

i don't want to put any power to the cable, im afraid to break it

am i doing something wrong?

by the way Tom66 the problem got worst,

it happens all the time without starting time issue.

Re: Hisense Plasma PDP4235EU

Lift the latch, push very gently downwards and it should slide out. Those cables are bonded to the panel, so you're right to be careful, as they cannot be replaced if they break.

Re: Hisense Plasma PDP4235EU

ok got it out!

tried to reseat the flat cables with no luck,

couldn't find a replacement Y buffer board.

model :42F1_YDRV

so i guess i will have to order a single chip and do that nasty work of soldering that chip back

i saw on Youtube that in order to check a chip, look for shorts between the power and ground.

Re: Hisense Plasma PDP4235EU

Do you have no picture at all or is the top 1/3rd black permanently?

Re: Hisense Plasma PDP4235EU

1/3rd top is black permanently,

Re: Hisense Plasma PDP4235EU

OK, then the buffer is not shorted. Replacing just that second IC should be all that is necessary.

Re: Hisense Plasma PDP4235EU

i will open an account on aliexpress and order that chip.

hope to update with good news.

thank you very much for now :-)

Re: Hisense Plasma PDP4235EU

Have a look around on several different sites first and check if it's available elsewhere for less.

Re: Hisense Plasma PDP4235EU

couldnt find this chip on ebay, and i don't really know any other electronics online stores,
i know it's not cheap but i got it for 11 dollars including shipping to israel.

i hope it will solve the problem, and even if it won't, its still worth the risk.

Re: Hisense Plasma PDP4235EU

Are you sure? I have never heard of a main board causing the part of the panel that should be glowing even with no signal to go out completely.

Re: Hisense Plasma PDP4235EU

hey william,
i've tried factory setting reset, it worked when i just got it,
(the problem was happening randomly)
(so i think it was just luck)

but over time it became permanent.
and the reset doesn't fix it.

Re: Hisense Plasma PDP4235EU

my problem was that the pic become smaller in the 1/3 off the screen (up to down) and after a wile become smaller from left to right.
so I make the reset process and its works costumer happy.
do you make the reset ok?.
