This old CRT set has provided ten years of trouble free service and I would not mind upgrading to newer technology BUT I'd rather wait a bit longer to see how the 2008 offerings pan out. Nobody local will do a housecall on the set to diagnose the problem. Getting it to the service center and back will cost around $200 plus unknown repair charges if indeed it is economical to fix it.
So, the questions are:
1. Does this sound like it might just be a blown bulb? How can I check out that possibility? I don't have a service manual. Is bulb replacement something a tech challenged owner can do?
2. If it is a bulb, what is the approximate replacement cost?
I am leery of dumping too much money in a ten year old RPTV but I wouldn't mind investing a bit of cash to extend its' life another six months or so.
Any insight, comments or suggestions would be appreciated.
There are no bulbs in your set. There are 3 CRTs, one each of red, green and blue.
The chance that it is a blown CRT are nil to none. CRTs virtually never blow, they usually hang in there for good and are usually still very much alive and well when the set is eventually put down. Something else is most likely the cause, here.
They are not easy to fix, tho, once something bad has happened to them, I personally won't work on one except for the convergence, because they are extremely technician unfriendly.
That said, the older TW series Tosh's had the incredible Designer service menu in addition to the regular sm, which D menu was later disco'd in favor of a much simpler and much more highly disguised regular sm, where if you didn't have the key, you wouldn't know the registers because they were no longer labeled. Just ID'd with totally generic hex numbers.
Your series of unit was the one Runco chose to be their flagship CRT RPTV at the time, great things can be done with it.
Very few calibrators will be able to really do it justice, tho, as very few present day calibrators know CRT tech very well, only us old-timers.
I typically find 2 of the 3 lenses on the typical CRT RPTV to be out of focus OOB, the grayscale will have drifted substantially over time even tho it may have been perfect OOB, and the convergence will have drifted off substantially as well, by now.
While the set doesn't have an awful lot of red push (blue-green diminish when fleshtones are prioritized) compared to lots of other brands, it can be totally realigned in the Designer menu. It could also benefit from overscan reduction.
If you want the best performance your set will deliver, you'll need to fly someone in. Plain and simple. Be ready for that and be shopping for who you want to do the job.
I vote me, because I have done many of the TW series and know the Designer menu inside and out. I can make your set look absolutey stunning. But you'll have to get it fixed first.
Good luck in any case, your set is excellent and capable of greatness -
