Problem is on Amp Assy. Resolder transistors and regulators that are mounted to the heat sink and replace both convergence output ICs. Replace the existing STK392-110 ICs with STK392-180 for improved reliability.

My office has the Prostar 816 phone and the manual is not detailed at all.. I needed to know how to change the time (due to time change) Our manual says #55 etc etc... Help me please!

To change the time on a prostar 816 you first need to be at a display set (doesn't matter what the extension number is).
with the handset down, enter #20 the screen should say MMC DISABLED
1) enter in 1 2 3 4 1 # (that enables programming

)
2) enter in #55 the screen should say YYMMDDWHHMM
3) enter in the year, month, day, day of the week, hours and minutes(the day of the week values are 1= mon. 2= tues. etc.)
press # when finished.

When I Turn on my toshiba 32AV500U there is sound but no picture

The problem isn't with the lcd panel, its with toshiba not willing to sell the backlight master or slave inverters seperately from the panel. If you check either the master or slave will have a blown 5 amp fuse, ussually 2 or more transistors inline with the transformer will be shorted.

TV Won't Turn On

Are you from US or Canada? I'm Panasonic authorized and allways Pana covered the warranty after 1 month from the expire date. Call Panasonic Viera service and tell them the story. I'm sure you'll get refound.
Anyway, a horizontal line doesn't mean the PDP is defective. It's one scan IC burned on the SU or SD board (depend where the line is). We allways replaced the SC bord each time SU or SD got burned. If after SD and SC replacement it still defective...yes the PDP has one scan line in short.
Call Viera and insist to get warranty. Let me know. Good luck!

Replace the FU303 fuse

I have just been buying it at radio shack. However in my case it seems once the fuse blew for the 1st time, it happens now every few months -- so must be a symptom of a larger issue.

Toshiba 50H81 TAC0151 Blowing Fuses, I Need schematic

Well without the schematic, knowing Toshiba they have alot of convergence problems, so see if the fuse blown in the convergence area, if you you may have to replace convergence amps. These are the big STK's. Most of the time there was a color problem with set before going out. If no problem with this on your set then look in the HV area Hor. and Ver. area. Hope this helps!
