Gray screen I have a Initial HDTV-320. The power goes on but the screen is dark gray almost black. No sound or picture.

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.
Take it to a repair shop.

Display or its board has got affected partially and might require the attention of a qualified service technician.

check your power supply use a voltage tester make sure your power supply has a 5v,12v,24v output.If no voltage is present replace the power supply.

Hello,

The problem with your lcd monitor is that the picture board of your lcd monitor is faulty that is why it power on for one second goes gray and finally black with only sound.

Since the power led button is on and it still give sound but no display, it means the picture board of your monitor is bad.

All you need to do is to take the lcd monitor to any local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix all alone in other to complicate issue.

Take care

Hello chrisuftring,

Here's a link to the wiring color code for the '95 Chevy Beretta.

You'll need to match the function of each wire from your head unit and the color code for that would be in your manual. Most aftermarket units are somewhat standard as far as power, accessory, ground, and speaker connections are concerned. But the wiring colors may be different for such leads as remote, power antenna, illumination, dimmer, and muting.

An Alpine head unit has the following wiring colors:
Blue - Power Antenna
Blue/White - Remote
Pink/Black - Audio Interrupt (muting)
Orange - Illumination
Red- Switched 12V+
Yellow - Constant 12V+
Black - Ground
Gray - RF Speaker (+)
Gray/Black - RF Speaker (-)
White - LF Speaker (+)
White/Black LF Speaker (-)
Violet - RR Speaker (+)
Violet/Black RR Speaker (-)
Green - LR Speaker (+)
Green/Black - LR Speaker (-)

With this head unit, you would wire Yellow to Orange, Red to Yellow, Black to Black, Orange to Gray, Blue to Pink, Gray to Light Green, Gray/Black to Dark Green, White to Tan, White/Black to Gray, Violet to Dark Blue, Violet/Black to Light Blue, Green to Brown, and Green/Black to Yellow.

Note that there are 2 "yellow" wires in your vehicle color code. You'll have to test them to determine which one is the accessory wire and which one goes to the left rear speaker. Using a 12V "test light" is the simplest. Connect one side of the light to ground. With the ignition ON probe the yellow wires. One of them should light the tester, the other one won't. Verify that the light goes out when the ignition is OFF and your have separated the redundant "yellows". The one that lit the tester is your 12V+ switched wire and the other one goes to the left rear speaker.

Hope this helps.

There are 4 capacitors on the power supply board that need to be replace. They are in the same area, same color, look for bulged caps.

The impoortant thing is if the pc will P.O.S.T.? (This is what its called when the motherboard performs its initial checks) If it is making it past the dell screen and then goes black there is a component that the motherboasrd is getting that just malfunctions and causes the blackout. Most common is a bad hard drive, bad battery, or bad ram
Try switching through thesre and see if that fixes you r issue

DLP TVs work projecting light throught a tube covered with mirrors, called the light tunnel.

The gray shadow it is something in the middle of the light tunnel, probably a mirror that has gone out of place when you moved the TV.

No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.
