Sourcing a suitable CRT

    Typical :(

    As I posted in a previous thread, my CRT TV died on me a few days ago. It's a 21" 4:3 Sanyo CE21DN9-R, just under 9 years old. I wasn't in the room when it happened but I saw a white flash coming from the room and when I went in, it was dead. Not a peep out of it, not even lights. Tested the fuse in the plug and it's OK.

    This TV had two RGB SCARTs (one was switchable between S-Video and RGB) and also supported NTSC via composite, which I'll need for my US NES which should be arriving next week. As much as I'd love to get this repaired, I assume it wouldn't be financially viable. So I'm going to need something equivalent. While there are people literally giving away CRTs, it's a minefield - most people don't even post the model of the TV, let alone whether it can take NTSC input!

    Any advice or recommendations on where to go from here?

    I'd open the case and take a look first.
    If you can find the busted part there easy to fix.
    Just don't put your fingers under the red suction cup.
    And don't be put off by people saying you'll die if you open it!
    Worth a look anyway

    I normally have no problem opening electronics, I've been taking stuff apart for years, but the voltages inside the CRT and line output transformer would have me terrified. Not too sure what I'd be looking for in there, either. Also, I live alone so if I did take a belt, there'd be nobody to help me! :o

    The fact I saw a flash is making me suspect a HT failure of some sort.

    So I grew a pair and took the back off! No obvious signs of damage in there. It was much cleaner than I expected; I remember my dad working on old Bush TVs in the early 90s and they were quite sooty.

    I tested the switch and fuse with a multimeter and they're good. That's about as far as I'm willing to go, though. A little knowledge is a dangerous thing.

    What happens when you plug it in?

    Nothing at all. The power light doesn't even come on.

    CRT TVs are cheap cheap cheap now, no need to even bother fixing this one.
    Chuck it in the bin and source a 20 inch Sony PVM :)

    Regarding the Sony PVM, would I have to do the RGB mod on the NES in order to use it on RGB monitors? I know that composite is terrible but it doesn't look easy to get RGB on the NES.

    All those Sony PVMs have composite in as standard. In fact, quite a few of the cheaper models are 100% composite with no RGB.

    You just need to get these BNC to Composite adapters.
