I apologize to the RCA guys but I agree with Walter about RCA's.
I would rather work on a Sanyo or Zenith.

Unusaul Coolant Leak - Fixed??Toshiba sucks NOT Reply=A0to:

Toshiba gives us less trouble than anything we sell or have ever sold.
I've had only one Toshiba to fail in warranty in over 2&1/2 years. I've
had 4 Hitachi's in that same time frame, and that's not bad either
considering the hundreds that we sell.
But, I constantly have RCA's in the shop. About the only time I see a
Toshiba is when Lightning gets them.
But anything below a 31" set is NOT built by Toshiba, and we don't sell
those.
I think that they should abandon the small set market, just because they
aren't up to Toshiba Quality anymore.

Just finished repairing this set. It was so hard to figure where the
leak was that I thought this may help someone else (other interesting
defects found)
1. Troubleshot
2. Located and replaced open 2A circuit protector in power supply -
=A0=A0=A0=A0=A0=A0at this time a portion of the green CRT
(picture tube) circuit
=A0=A0=A0=A0=A0=A0=A0=A0board immediately started burning up
3. Examined area around green CRT and found a few drops of liquid
=A0=A0=A0=A0=A0=A0leaking from the CRT onto the circuit board (cause of
burning).
4. Removed the green CRT/assembly - checked carefully for leaks (no
=A0=A0=A0=A0=A0=A0longer leaking! - so obvious sign as to where
it leaked from)
5. After hours of waiting for it to leak, and more tests, a loose
=A0=A0=A0=A0=A0=A0filler plug was found (buried under silicone sealant).
We added
=A0=A0=A0=A0=A0=A0more coolant, tightened it (was not leaking at this
time), and
=A0=A0=A0=A0=A0=A0=A0=A0sealed it with silicone sealant.
6. Repaired burnt wiring on green CRT board
7. Reinstalled green CRT/assembly
8. Adjusted convergence controls
9. Tightened loose lens wing nuts (not done properly at factory)
10. Cemented totally loose convergence adjustment tabs (another
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0big mistake at factory)
DOES TOSHIBA SUCK OR WHAT? -
This is not the
first time I am seen
loose lens wing nuts, not to mention almost every direct view Toshiba
I see having very green grey scale. But then it is good for business.
