Ghetto mod Polariod TDA-03211C need help
I read many posts on this model that say it has a defect that causes its death when used as a VGA monitor, to the point of someone saying that whenever one shows up at his shop, he asks the customer for permission to epoxy over the VGA connector.
I got this one in, fixed the bad capacitor problems, it fired up, but using it as a VGA monitor killed it again. This unit is useless to me unless I can use it as a monitor.
So, I decided to ghetto mod it. My plan is to gut out the tuner, power supply, and inverter, and try to mount a Dell Inspiron E1405 laptop which is missing its screen onto the back of the panel so I could use it as a 32 inch all in one computer. If that fails because of video cable or resolution incompatibility, then to attach one of those cheap ebay universal VGA driver boards. The video cable from the Dell would appear to fit, but I'm thinking it might be 3.3V and the panel probably 5V. Does anyone know this for certain?
I would like to hack the panel to use a different inverter method, and I would appreciate any thoughts on using 7/11/13/15/18 watt fluorescent bulb sockets to light the bulbs inside the panel. I realize that this forgoes a brightness control, but I can live with that if I can get it to an acceptable brightness level. Apparently, there are 16 bulbs inside the panel, and two wires / two inverter transformers feeding the high voltage into the panel.
Does anyone know if this panel grounds the negative side of the tubes to the panel's metal back? I take it that this panel is using 2 banks of 8 tubes in parallel?
If nothing else, I will replace the tubes with LED 5050 strip, but I know the bulbs are all good, and I think a couple of fluorescent light bulb socket bases would get the job done well enough if I can figure out the right wattage to use. (I know not to use a dimmer with these lol)
Any thoughts you may have on this would be greatly appreciated.
