Re: toshiba regza no picture

You're going to have to squint to see the text but it's just about there.

Look in the service manual for configuration of panel options. Looks like you have to set variables individually.

No, I don't know the code.

Got the service manual?

Got the code but cant open owt up to change

Tom is the sevice menu a sequence on the remote? if so i dont suppose you know the sequence fella..thx

Re: toshiba regza no picture

This is caused by having the panel model # set incorrectly.

Go into the service menu and adjust the panel settings until the picture restores.

Re: toshiba regza no picture

Got hold of a 37av55d model with smashed screen for 25quid cos the mainboards are the same..fitted board into 32" and the picture comes on but its not right..i can only discribe it like in the film predator the different visions the alien has..theres nowt loose so i dont know what to try..the only way to nearly have a good picture is to turn the contrast to 0 & thats in every mode ie dynamic/movie etc..

Re: toshiba regza no picture

Ive only gone an bollocked this board up
I was removing a leg on a diode to test & ive caught a tiny smd cap i think that was along side it..so i tried to solder it bk & sort of lost it...so its defo another board now...that micro small soldering stinks!!!thx anyways guys

Re: toshiba regza no picture

Indeed there are many .
From the schematic they sit at the input to and from every regulator and
critical chip Vcc,there are quit a few supplies on this board...
2 x 3.3 v
1 X 5V
1 X 1.2V
1 X 1.8V
1 X 2.6V

All derived from the PSU @
1 X 5v
1 X 12v
1 X 18v (audio)
1 X 24v high current for the supply

All "FL" components read very low ohms as would a fuse.
All inductors are designated with an "L"

Edit found them...typical one BKP2125HS221-T
220 ohm ferrite bead inline
Where they are placed would act as a fuse during an OL situation !

Re: toshiba regza no picture

I'm not sure they are fusible links as you would only have a few of them on the board and only near PSU inputs and things like USB... ???

Re: toshiba regza no picture

"them 2 small diodes are they supposed to measure the same as other diodes infinity or O.L 1 way & a reading the other way cos these 2 diodes have readings both ways..thx"

Which diodes? Probably yes or at least a big difference - can you unsolder one leg

Electrotanya - if you are not registered only allows two downloads (or attempted downloads per day) Im not registered and often double click and get two downloads of the same item "!!£"$%^"

There is only 2 diodes on the underside that measure O.L & a reading all the other diodes measure readings both ways..im hoping they are supposed to do that cos that is some steady hand desoldering..thx

Re: toshiba regza no picture

Yep those are crystals, are those the only ones?

yep they r the only crystals on this board X8001 is 20.000 F:86 & X1301 is 120E8C..thx

Re: toshiba regza no picture

Is this the micro area & is that another crystal at the side?..them 2 small diodes are they supposed to measure the same as other diodes infinity or O.L 1 way & a reading the other way cos these 2 diodes have readings both ways..thx

sos forgot the pics

Re: toshiba regza no picture

Cant download from ET..i wait till its says get manual then it says not logged in..thx

Re: toshiba regza no picture

Do you mean cant download from ET or cant get them to run. If the former have you remembered to disable any adblockers.
