Hi,
If you've already checked and confirmed that the bulb is not the caused of this symptoms, there's two probable caused of this fault.
1. Most likely the inverter board problem - Once this board was dead, there's no high voltage supply will produce to lit the backlight resulting to black picture. You must check it for open fuse, fusible resistor in line with shorted driver transistor, open driver transistor, open high voltage transformer.
Another caused why the inverter board is disable is when it gone to overload which is caused by shorted high voltage transformer.
2. Power supply failure - once the supply voltage feeding the inverter board is gone, the inverter board is disable. You must check the output of the power supply feeding the inverter board to determine where the fault came from.
You must prepare some tools and test instrument and know safety precaution in troubleshooting, know how to test the affected parts if you are going to fix it yourself or else I would advice you to look for a qualified technician to isolate the faulty parts.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hello i have a toshib 42 rv530u lcd set and it just went blank on me after watching it. the sound is still heard but no picture


Either your screen went, the bulb went or the bulb's inverter went. Bulb replacement in LCD screens, especially this large, is a very sensative procedure and not recommended without years of skills. Replacement of the inverter board is easier adn do it your self would cost betwen 60 to 150 USD. If it is the bulb or the screen, it will be more cost efficient to replace the unit. screens for this would cost 300+ USD

The new bulb that went bad I purchased for less than $130.00 from http://www.Discount-Merchant.com/ . When I called them they immediatly sent me a new bulb free. Their number is 1-619-710-2637. A very good coumpany to do business with. They are also considering selling ballast for dlp TV's for around $200.00. The TV repair place that I have been going to told me that maybe the ballast made the bulb go out and it would cost between $600.00 and 800.00 to have them fix it. My TV is a Mitsubishi WD52725. dodger1
