It has power but no sound and no picture. TV turns on and power button flashes about 12 times and then stays blue.


Hi Dustin,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

I found a replacement Scheda power module at you guessed it, not at Toys R Us but rather at www.tvmodulesrus.com for $79. The same module is used in several LCDs, including our PowerSpec 30" LCD sold at Micro Center. It is listed under several numbers at TV Modules R US:

P/N: 6693006610
Model: HOAU242001(A)

Sceptre X30SV LCD display goes black with sound... Inverter? and other parts...


I too have the same problem...Searched and waited long time for parts. I have replaced everything and the thing still flashes and goes blank but has sound. Not worth anymore stress. My neighbor is an electrical engineer who I used to think can fix anything. He too is baffled. My fix suggestion... Getting a new LCD (not a Sceptre) tonight...with an extended warranty...Sceptre (and their tech's) no help if you don't have a warranty. I learned my lesson!
