Sony Bluray Player problem

[caphair]

So I have this smart bluray player that when a disc is loaded says "no disc" however if I keep ejecting and loading real quick it'll eventually read the disc and play fine, no skipping, freezing etc.

If the disc is removed and another loaded it's always a gamble if it'll read it initially. Most times I have to keep quickly pressing eject to get it to load.

I tried cleaning the lens, there aren't any pots on it to try adjusting the power.

What I'm curious about though is if it's a weak laser issue if sometimes it does detect a disc and play flawlessly. Wouldn't a weak laser have trouble reading all the time?

what does it do with dvd's or audio cd's?

Re: Sony Bluray Player problem

Same thing happens with various disc types

Re: Sony Bluray Player problem

then it's not the laser, because there are different lasers for each disc type in the assembly.

have you opened it to do a visual check?

Re: Sony Bluray Player problem

I have nothing looks out of the ordinary and I tried moving the lens forward, back etc to see if it alters the operation. But it didn't do anything.

Any ideas?

poor psu smoothing effecting focus?

Re: Sony Bluray Player problem

Hmm I wonder. I have noticed that if it has been playing a disc, if I change it it'll read it almost first time every time. But if it hasn't been used, it gives the no disc error.

Re: Sony Bluray Player problem

maybe a slightly worn/sticking motor that spins the disk up to speed?

Re: Sony Bluray Player problem

I think the way this one works is the motor spins after laser detects a disc. It's the same laser in the slim ps3s

Re: Sony Bluray Player problem

whats the model number of the player?

Re: Sony Bluray Player problem

Sony BDP-BX37

Re: Sony Bluray Player problem

I've also noticed the lens shifts a quick three movements/jerks before it says no disc, when it works it either doesn't shift or shifts one or two times before disc spins up and loads

Re: Sony Bluray Player problem

Did you try audio CD or regular DVD?

[caphair]

Re: Sony Bluray Player problem

I tried both and same issue

[caphair]

Re: Sony Bluray Player problem

It's just strange that once it loads a disc, and has been playing for a good 20 min it'll easily detect another one until the unit has been turned off for a while then it's constant "no disc"

hmm that sounds like a bad solder joint issue. it doesnt work when its cool cuz the solder contracts and doesnt make contact. then when it heats up the solder expands and contact is restored. could also be badcaps in the psu of the player, mainboard or bluray drive.

Re: Sony Bluray Player problem

There are two smd electrolytic caps that provide 12v and 5v to the motor and lens, I replaced them out of curiosity and no change in operation.

Caps on PSU all look good, no esr meter to know for sure though.

Could check if it's temp related by hosing it down with a hair dryer. Don't the lasers in the ps3's fail quite a bit ?

Maybe the heat thing was a fluke, tried it this morning after itd been unplugged all night. Read disc first attempt, then nothing for a while after that.

If it's the laser, just don't understand why it'd work randomly and read six perfectly until it's removed.

Re: Sony Bluray Player problem

the laser in the ps3 is pretty reliable, they just dont like being dropped or banged around - it makes the optics come loose.
