Prob with CRT Replacement

OK, I have 2 Toshiba 9" TV/DVDs. One (brand new, ebay, $20)had a gassed CRT, so I took the tube out of the other one (ebay, $1, scratched up case) which worked perfectly. The first one works fine with the replaced tube. Now 1 1/2 years later, I buy a "new" CRT, (ebay) same part#, to get the second one up and running. After installing the tube, just a bright dot in the center of the screen on power-up. All the connections went normally. Is this indicative of a defective tube? The set worked fine before removing the old CRT. JR

That was almost too obvious.

I missed it because he said "all the connections went normally".

I really can't see how anyone could just "miss" the deflection cables, let alone the coils...

How did you miss that? Normally the yoke is swapped over from the bad tube to the new one.

Guess he pitched the bad tube with the yoke.

Good luck. It's unlikely that the yoke is available anymore, and it's a critical component specific to the chassis it's designed to work with. Best bet is to find another identical unit with another problem and salvage the yoke. Some tubes have bonded yokes, the rest will not include a yoke.

As James said, they tend to be chassis-specific, and it's unlikely that a 'transplant' from a different one will be successful in terms of geometry etc, even if you persuade the set to start up after fitting them ...
