FL Inverter Board adjustment

I had problems with my inverter board and had replaced it myself. It works only marginally better but seems to still turn off whenever I crank up the contrast too high. I noticed a small potentiometer on the board though and am wondering if it can be adjusted to prevent this from happening or if it shouldn't be touched at all?

Dear User, I would suggest not to tampering with your lcd inverter potentiometer, as it control the amount of voltage being use by the lcd montior. As you have seen from earlier event, it turns off once it reach a certain point. In which, whats really happen is that its reaching a certain temperature and voltage, to which it's shut off to save it's self from burning out. It can also be the lcd inverter was set wrong from the manufacture, and turns off just like before.

I have a hP pavillion dv2620us. I get an intermittent black screen whenever I use the laptop. During normal use, the laptop screen just goes dark/black. There is still power to the laptop and you can sort...


1. Test using an external monitor. If it works, then either the screen bulb or the inverter board might be defective.
2. Test the inverter board. Easiest way to do it if you have a good screen with a good bulb. Connect the good screen to the inverter board & test it. If it lights up, then the inverter board is good. If it did not, then the inverter board is bad & needs to be replaced.
3. If the inverter board is good, then we are left with the possibility that the screen bulb is bad. To fix this, we will need to replace the LCD screen.

Ok I've got the common power inverter problem


Check the SMD fuses on the inverter board see if any of them have blown. You will need a continuity meter to check this.

New Power Supply


Saadi2,

In my line of business I have purchased over 20 of these units. The power supply is listed on the Viewsonic Store web-site. Part# is B00005305 cost is about $65.00. Being a Tech myself I went the route of replacing individual parts but had no luck. Take into consideration time to repair its cheaper to by the replacement board. You can always fix the damaged board later as a back up.

Good Luck, OTBMAN

Sanyo lcd 32" vizion integrated hdtv


I have this tv as well with the same problem. From the research I've done, one of the 16 ccfl's(backlight bulbs) goes bad and they all will not come on then. I have not been able to find a replacement ccfl for this particular tv. The ccfl size if 3mm x 711mm. I have a feeling the scope of this problem is very large with this particular tv and this forum represents the tip of the iceberg. Sanyo unfortunately makes a piece of junk and we have that piece of junk sitting in our homes with no good solution other than to say, dont waste your money on another Sanyo tv.
