The freqency /time display doesn't blank any of the center segments on
either time or frequency function.  Any suggestions on a fix appreciated.
The serial number is 59,800 and I wonder if anyone can tell me if this is an
early or late model?

I need a replacement for a diode used on a nissan gauge cluster, when you hold the diode vertically you see M1 and while rotating the diode there is also a  dot ( . ) and then 80...
this is the best way I can explained it .....
thanks
I guess is some kind of SMD marking

Hi and Happy New Year from Sydney!
Im hoping I can obtain some advice on my TX-33V2X currently awaitin

are the problems.

My vertical deflection has collapsed to a 1" line.  If you smack it, i

not worked on this model before. any body had this problem or have any
ideas thanks  jack@allen park tv

Some of you guys misunderstand what I want!
How do I get into the EEPROM, & Micro, in
order to change the parameters! Example: The

Hi and Happy New Year to all,

After few seconds from line power-up, the Led turn ON and  with a relais

I'm looking for a datasheet for the above component - I've searched all over
the net and can;t find anything. Does anyone have a datasheet or can tell
mewhat this semiconductor is?

I would like to know how long for is possible to store, and in wich
conditions (temperature), the out of production mercury cells 1.35Volts
PX625.
They are infact now rare, due to the mercury contained iside that creates
