Go over any place on the PCB that looks "dark" or different very carefully with new solder and make sure it's all reflowed.

Also reflow anything that is big and heavy (like the flyback and big resistors) or connectors (because they get stressed).

It's also likely that the caps need to be checked though.




Andy and Matt's database claim that it is fully an Orion set that was rebranded with a Toshiba badge. But you don't have to take my word for it.

Thanks for the help. I will likely be doing what you suggested. As far as I can tell, it is incorrect that Orion made the tube in the 27A33. Orion did manufacture the circuit boards and TV casing but for the Toshiba 27A33 model but as far as I can tell, they did not manufacture the tube. It was a common practice for Orion to use tubes in their Orion branded CRTs that were manufactured by other companies and in this case, Matsushita (AKA-Panasonic) was the company that manufactured the tube. Like you, I originally thought that Orion manufactured the tube but after having discussions with knowledgeable people on the CRTgaming subreddit and the CRT Collective on Facebook, it seems that this isn't the case.

I also have a Panasonic 27" CRT TV (model CT27D11E, made in 2001) and the tube in that set has the same codes on the label as the Toshiba 27A33. The codes on both tubes are E118951 and LR29056. Another similarity between the tubes is that both tubes have a bold "M" at the top of the label with a square around it. This is the symbol that Matsushita used on their tubes to indicate that they manufactured the tube. This is the symbol I'm referring to, https://deskthority.net/wiki/File:Br...(IE139097).svg. Another piece of information comes from the Union Electronic Distributors website. They have been one of the largest suppliers of consumer electronics parts since the 1950s. The following link shows the tube in the 27A33 (tube # M68LWF088X50) as being manufactured by PANASONIC (MATSUSHITA), (https://www.ued.net/ued/viewItemActi...68LWF088X50Y5P). The picture also looks very similar on each set. I made a post on the CRTgaming subreddit asking about this, http://(https://www.reddit.com/r/crt...icture_tubes/).
