Toshiba TP50F60 Failure
 
My Toshiba projection recently failed. Front LED light would blink on and off continously. TV would not power off. I had to pull the cord from the socket.

However, after TV sits unplugged for a few hours, the TV would turn back on after it is plugged in. TV would operate normally for 20-minutes or so before turning off again. Same problem as before - LED would blink continously. Picture is perfect. No distortion when it is on. Therefore, I do not believe the 'digital convergance' is the cause.

Anyone else having these problems. Please advise. Thank you.

Other than just cycling the thing on and off what actual diagnostics have
you made, S.A. Voltage measurements while working and not working, Etc??
Many things may trip the protective shutdown inclusive of the registration,
beam current, etc.

Agreed, there are lots of things that will put the set into protect
shutdown.

That being said, the symptom is typical of a somewhat common failure on
the stand up board that has a high value, 82K I think, 1/8 watt
resistor that is on the 200LVP, 200V low protect, that commonly will
increase in value and cause intermittent shutdown. It has been a very
long time since anyone has wanted to spend the money on fixing one of
those old beasts, good set though as long as the tubes were not
overdriven.

Any good technician will be able to repair this issue with the above
information and possibly a schematic if needed. Most of Toshiba's sets
from that era had the connector pins labeled.

Does anyone have a schematics of the TOSHIBA TP50F60. I need to know which board to remove and exactly which resistor needs replacing. Thanks for the heads up.

Also, if I want to measure voltage what section of the board should I start? and if I want to over-ride the auto shutdown feature, which chip(s) should I remove?

No offence intended but...

Questions like that indicate you should not work on this TV

The problem may be that particular resistor or something else. You will
probably need some troubleshooting skills.

Also, you don't over-ride auto shutdown features except in a rare
momentary time of measuring where the problem is.
If you over-ride the protection circuits, the TV will self destruct.
It may simply go out with a puff of smoke or it may burn your house down
while you're sleeping.
Please be careful.

Glad you cleared that up, Kip. I thought maybe we were going to have to
refer you to Mark for some counselling. :-)
