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.

Unplug it, otherwise more damage will be done to other circuits. It has bad power supply due to bad caps, replace them in a set with the correct type.

I have exactly same problem


Sound like your display is having issues with the inverter board. When the power supply detects a short circuit, it turn off by itself. When you try several times, you may be able to "bypass" the circuit protection but the damaged parts still having problems. This issue may be related with the DELL display issues.

The display needs to be fixed by someone with experience in electronics repair.

Screen goes black but power light stays on


Hello. I had the same problem with my X2gen 19" (model MW19R)monitor. In my case, the monitor would turn off after 20 seconds or so but the blue power light would stay on as well. I had to replace a high voltage capacitor located in the backlight power supply board. There are 4 blue capacitors on the board which are identical and they are marked as 27J 3KV. Fortunately, I only had to replace one of these capacitors ( it was turning a yellowish brownish color ). Hope this helps.

MONITOR KEEPS SWITCHING TO STANDBY


Either the power supply is going bad (power light will be orange or off when it goes dark) or the screen itself has the problem (inverter?). If the power button stays green but the screen goes dark, that'll be the problem.

Power Problem


The hissing noise on your speakers is because of arcing. Do not try to operate repeatedly or you may do severe damage. The most likely culprit is the inverter board but you will have to disassemble the monitor to find out. Any loose connection that results in an arc will create noise on speakers. Hissing is usually a result of the high frequency/ voltage output small enough amperage to not blow your power supply If it were a DC arc you would just get a one time pop.
