| Lightbox from a discarded LCD monitor. |

Hot glass is basically anything to do with molten glass. In my partners case she's an artist that makes anything from simple glass birds (as in the picture) to sculptures by melting various colours and types of glass together in a kiln. The light box is useful to her since it allows her to see the colours and properties of the glass (saves holding them up against windows!). Most light boxes are sold to artists of one type or another, useful for painting on stuff, copying etc etc. In terms of reliability - out of all the 'broken' monitors I've acquired only one had a duff inverter for the cold cathode tubes. You've also got to look at how long a lightbox spends turned on compared to an LCD monitor which may never get turned off! Also, sooner or later there are going to be LED backlit stuff floating around... ;-) |

now I know what to do with my dead monitors very often the monitors fail, when the capacitors in the power supplies go high resistance the capacitance may be ok but the ESR will of increased ,a domed top will give them away, some times use 105 c types for replacement if you decide to repair the monitor depending on the monitor size an external 12v dc @ 1.5 amps psu could be used to power just the back light ps the acer x221w I fixed several weeks ago had 1000v drive to the four tubes !!! the large brown in the photo could have 340v on it if not discharged |
