Mitsubishi CT-2893am vertical fault |
|
|
I'm visiting friends who have one of these TV's with a flat horizontal line.
It was in storage for 12 months... then 10mins after switch on it developed
the fault.
I've only got very basic tools and an analogue mm, and no circuit diagram
either :(
I'm not sure exactly what components are associated with this part of the
circuit.
The HV caps C906, 915 and 925 check out Ok as far as leakage and checked a
few low value resistors.
A burnt out track between C956(neg) to D556(anode) has been repaired at some
other time. No history on that fault.
If anyone has had any experience with this fault in , a standard list of
components worth testing or replacing or any other clues... it'd be much
appreciated.
Thanks in advance.

First of all... Sound like a Pro... Say My T.V. Lacks Vertical
Deflection... then replace the 100uf caps in vertical cir. |

You may just need to solder the vertical IC, but check the electrolytic
capacitors arond the IC, even if the IC only needs soldering. Sky

Also any small value electros (1uF-2.2uF) related to the vertical
circuits.

Thanks all for the input.
I'm not actually a TV tech, but electronics is electronics.
BTW - I wanted to sound like a pro, but too long around customers...
I figured it was just a broken wire / blown fuse / needs a clean... it won't
take long to fix because it was working this morning...it probably just
needs a new one of those big globes in the front. :)
