Sceptre X505BV no power


Could be an open internal fuse or power supply failure

Sound but no picture


Try replacing the bulb, checking the power supply for a short circuit and examining the motherboard for burn marks or other signs that the screen's gone bad. Worst-case scenario, a new 32" TV costs a lot less than it did a few years ago, and Newegg.com often has good sales.

Sceptre X7G komodo II Power light and screen flash about every second. Could it be the blanking circuit?


Look for bad caps with domed tops as shown in my pictures here: http://s807.photobucket.com/albums/yy352/budm/SCEPTRE/Sceptre%20X7G/
should repalce the caps in a set.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

Sceptre X9G Komodo IV 19" Monitor


Hi dgp1952, Check with www.lcdrepair.net if you want a repair. Something is wrong with your backlight or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. Dust can cause the circuitry to heat up faster and put the power supply into Clamp mode. Clamp mode will turn the supply off to certain circuits which may be the reason your display is going black after 5 minutes.

Sceptre X9G-Komodo IV


I recently came accross one of these monitors (Planar PE191M) with the identical issue. The resolution was to replace the two 470ufd 25V capacitors that are located on the main power board. The main power board also contains the audio circuit and more importantly the inverter circuit that drives the CCFL backlighting. The suspect caps were identified using an ESR meter; if you happen to have one of these meters you can confirm this is the issue with your unit(s), alternatively you can just replace the two capacitors and see if it resolves your issue. Hope this info helps someone out there.
