You can have bad lamp problem, you need spare lamp to verify if it is the inverter circuits or the lamp problem. How are the 5vdc for the logic and the 12~18vdc for the inverter circuits?

This Acer 2416w has problems with weak capacitors on the inverter board causing shorting of the driver FETs. Replacing caps and shorted FETs may solve the malfunction.

I have Toshiba 15" lcd tv with vestel 17ips01-2 psu/inverter board.the tv will show a picture for a couple of seconds and then the inverter cuts out.


There are a few things that can cause this fault, but the most common is the High Voltage Capacitors that feed the backlights going bad. The invertor and power supply are on the same board (Vestel 17IPS01-2)

The caps are on the power supply board and are C355 & C356 (12pf 3kv) and C354 (4.7pf 3kv). If you replace these caps it will solve the problem in 99% of cases.

If replacing these three caps do not solve the problem then it may be easier to replace the power supply board... as fixing means replacing a tiny surface mount chip with loads of legs.

WARNING: The Power Supply/Invertor board can contain LETHAL VOLTAGES even when turned off and unplugged. if you are not sure, Pay someone to do it for you!

SCREEN GOES BLACK AFTER A FEW SECONDS AFTER TURNING MONITOR ON.


More often then not, this is attributed to a failing Backlight Inverter. A Backlight Inverter, is a power board mounted below the screen that actually send power to the Lamp inside the LCD itself. Check to see, when it goes out if there isn't still some images faint in the screen. If this is the case take it to a local repair shop and have them order one and replace it. repair cost for this shuold be around 65-100 dollars.

If this helps, please rate my solution. Have a great day.

Replacing Inverter Board


I did some poking around and only found a few places that sold inverter boards for this monitor. Ebay has one that sells for about $80: http://cgi.ebay.com/Backlight-Inverter-for-Gateway-FPD1930-LCD-Monitor_W0QQitemZ160070918225QQcategoryZ174QQrdZ1QQssPageNameZWINQ3aPOST0Q3aRECOQ3aBINQQcmdZViewItem I wasn't able to find any specific instructions posted, however, taking a typical LCD panel apart and replacing the board shouldn't be too difficult. The only hard part is not getting shocked, which is why this is not a job for the typical user. Anyway to disassemble the typical LCD you remove the pedestal from the back of the LCD then remove the screws around the back of the LCD, remove the back and look for the inverter board. Typically it is covered with a metal shield; again the hard part is knowing how to correctly handle the parts. Considering you can buy a new 17" LCD for $120 to $150 (and has a 1 year warranty) you might want to consider investing in a new monitor instead. If you have any other questions let us know, otherwise please don?t forget to rate this posting.
