I have a Toshiba Regza 32" LCD TV.I get sound but no picture. I can get picture after turning the TV on-off-on (results vary).Any suggestions?
Model: Regza 32" LCD
I cannot locate the model#. I have taken the back off to see if i could identify the voltage inverter but have no clue what I am looking at.
Hi,I cannot be exact without the model number, but from a Toshiba LCD training manual for the 32 inch series the inverter is identified below as the DC-DC converter:The white wires on the left, from the power supply should be providing about 24vdc (most models). If the back of your set does not look like this - look for a board that has a few chips like the square ones with the round imprint on the picture - and that will be the inverter module. Your symptoms do indicate an inverter failure, but check to see if the 24vdc voltage is present.Thanks,Rod
I found the model #32HL67
I don't see anything like the picture on my set.
If the invert is the problem, is it worth replacing?
Hi,I only have technical specifications for that model. It has two inverter boards - a master and a slave. Normally, its the master that fails, your master board looks like this:A refurbished/salvaged unit can be purchased for about $80. None of my suppliers show a new board available.As I mentioned, double check to ensure that there is 24vdc provided to the board - this will be located close to the white connector on the right of the picture - you can use the + side of the capacitors as a measuring point.Thanks,Rod

It is behind alot of other electronic boards. If I try and get to it, I am going to break something else. I may as well cut my losses.
