Toshiba TV29C90 problem; Image fades to black...

Mark D. Zacharias spake thus:

Been having bad luck lately with lamps from MCM and the like.

Anyone know a good source for high quality bi-pin, fuse-lamps, screw-base,
wedge-base lamps, etc?

6v, 8v, 12v mainly.

I was able to find some of them little "hot dog" bulbs (for a Marantz
receiver) right here in Berkeley at my favorite electronics store, Al
Lasher Electronics (http://www.allashers.com). They were 16 volts, I think.

Dunno if this will do you any good, as I'm not sure they do mail order
(but it may be worth checking), but I wanted to point out that there are
still a (very) few *real* electronics stores. This place has been around
since the 1940s, has tons of old stuff, and is as far from a Radio Shack
as is possible.

Resolder the crt socket , if that doesent work it could be the video
cable , they often get bad connection right after the 15 pin connector
.. Try flexing it while watching the picture .

**Old Marantz recievers were 8 Volt 200mA. Blue Lumileds are a MUCH better
choice. They last forever, consume far less power (around 15mA is plenty)
and look way cool.

How exactly does that work with the LED's? Does one mount them using the old
lamp as a form? Do they require limiting resistors? Perhaps I should just
buy a few and experiment, eh?

Resistors required. Diodes not required but will help dissapation if on AC.
You will have to experiment to get the mounting
and diffusion.

All Electronics carries fuse-lamps.

I have used LED's -- suggest this -- you can get the surface mount variety
and mount several in series such that the forward voltage drop approximates
the voltage available, then use a resistor to limit current -- the SMT
devices can be attached to a rod of plexiglas -- they will last thousands of
hours if you limit the current to a few ma.

That's too bad, because the Marantz lamps are actually little fuses. It
would be nice if there were a snap-in replacement for them, complete
with resistor. As it is, it would be pretty difficult to put in a LED
and resistor without some pretty ugly jury-rigging.

(And yes, they are 8 volts.)

I have seen LED replacements for Marantz fuse lamps on eBay at 5.99 / ea.
plus freight. The pics don't really answer the question of how they are
built.

You could try swapping the original for the 10K or 47K version. For a
mere 38p it would be worth trying it out. My guess is you wouldn't
notice a whole lot of difference (if at all) over the 20K version.

Err. Nope [crossposting to sci.electronics.repair & uk.d-i-y]

I have been given an ex-rental Granada Finlandia Video Recorder. It works
fine using all the buttons on the machine, but, it has a remote control
which has a LCD screen and I have no instructions for it. I can't even find
anything on the net. Certain remote functions work ok but having difficulty
trying to work out how to do timed recording.

Anyone help please....

There is no model number on the unit only a serial number..... and DPSS on
the front of the machine.

The machine is made by Sharp. DPSS (Digital Program Search System) is
their invention.

So after a google for "sharp finlandia" we come to this list
<http://www.hamradio-badarc.co.uk/video/vcreq/eqvcr3.htm>

Granada VHSLY1 Sharp OEM Finlandia
Granada VHSLY2 Sharp Finlandia
Granada VHSMY6 Sharp VCA50HM Finlandia

This might get you a little further with a google search, or someone
else might now recognise it!

for your interest, this is how the model number was made up.

VHS L Y 1

vhs - video

L - year of model. same as car registrations
Y - manufacturer ( y sharp)
1 - technology level. 1-7

1 - basic, 7 - nicam 4 head, top of the range etc


dpss as you say is sharp.

there were lots of sharp models.

is there a sticker or model number on the back ?

there should be

I ordered an ESR meter from John's Jukes on Monday and it got here (Florida)
Friday. Wow! Fastest shipping ever from Canada! That was quicker than if it
were coming from somewhere in the USA.

Thanks for the advice everybody and Thank you John for the quick shipping..
Now I can get started on soldering this thing togeather

All the more interesting considering it wasn't shipped until Tuesday -
we are closed on Mondays. I don't like to promise fast shipping, but
normal seems to be 3 - 5 business days, with the odd one taking 10
business days (two weeks). Customs...
