Wards Signature 2000 TV - no service support anywhere?
Hi all,
I have my Mom's not too old 20" TV which is a Wards Signature 2000 model JSJ12022 Suffix A. It is probably a victim of a lightning hit. I can see a burned diode on the board - so burned, in fact, that the solder has melted on the other side of the board on the diode leads and leads to a couple caps and resistors near it. I have the owner's manual - but there is no schematic in it. An exhaustive search of the net reveals nothing - not even a source of any Wards service info that I could take this to. I know the unit was built by SHARP in Sept 1994. It was distributed by JRI Distributing, Inc; 619 West Chicago Ave, Chicago 60671. I seriously doubt if JRI has servicing info, tho. Probably just some guy who rented a warehouse back then. The main board has numbers: (P8269PE) and PWBF8269PE and also DUNTK8269WE and also 8269V3. I searched on all these numbers on the net. The only results I could find in my search were that Wards is defunct. bankrupt, and any service agreements are taken in the shorts... The problem: The burned diode is D752, with scorched areas at C725 and R754. I don't want to just stick in "any" diode and plug it in, of course.. The set does not come on - I hear a click after the power switch is pushed but nothing else. Nothing else is burning - the damage is complete. Does anyone have a service manual or a Sams Photofact number for this TV? ~Tom in Mn nocone (at uslink) (--dot--) net |

Try visiting Howard Sams website.
http://www.samswebsite.com/photofact/pf_search.asp I didn't see your model listed, but you may e-mail them to inquire if they can get or have info on a similar chassis. I also believe Sears picked up some responsibility for some Wards maint contracts, but not sure if TVs were included. Didn't find any info on Sears site. "Nocturnal1" wrote in message ...

Thanks, Ray. I checked and could find nothing even CLOSE...
The photofact search engine really reeks, too - can't browse like most (that I can see). ~Tom "Nocturnal1" wrote in message ... Still no luck and no responses here - anyone???? |

Well, the only solution I could offer is to try to look for service literature
for a Sharp TV set of the same year and type that is as close as possible in design. - Reinhart |

I think its demanding too much current, or over time heat just killed it.
I had the same issues with my currently working NEC projection set, (yes the picture tubes are shot, IMHO i think generics would work). I replaced and resoldered the diodes, and it works great, so try that. They just die with heat, but then again, your HOT could be bad. "LASERandDVDfan" wrote in message ...

It isn't worth anything to fix, except the satisfaction of fixing it, unfortunately. H. R. (Bob) Hofmann |

Thanks to all who replied. I will try a new diode and resolder the board
connections that melted and see if it does the job. What've I got to lose? ~Tom |
