"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

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... ???

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 !

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

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..

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

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.

Dont suppose any1 knows how to install this zeus correctly..ALL I WANT TO DO IS READ THIS FRIGGIN SERVICE MANUAL..thx

[cashkennedy]

Re: toshiba regza no picture

What is zeus? why are you trying to instal it?

To download the service manual

IE9, chrome, and firefox's latest versions should all work

To open the service manual

adobe reader , or nitro pdf .


those are for pc though, if you have a mac why are you even trying to fix shit, everything just a disposable electronic.

Re: toshiba regza no picture

You need this to read the service manual for some stupid bloody reason:

Re: toshiba regza no picture

Hehe sorry it was just a joke about mac people being idiots (wasnt aimed at you in particular as im pretty sure you have a PC)


What file ending is the file you downloaded?

Or does the file you downloaded from elektro tanya just have an exe that the manual is part of?
