20 Most Recent Microtech JTX V5 15" Flat Panel LCD Monitor Questions & Answers


The back light is failing, and possibly the power capacitors for the HT circuit are failing to store the voltage necessary to power the screen, which would explain the flickering. This needs tested by an expert in monitors and TV's to confirm the actual source of the issue

If the brightness issue is simply the setting: open the OSD (press the left most button) Highlight the Graphics option sub menu (by pressing the Function button, the second one from the left). This has an icon with three vertical bars (labeled RGB). Press the third button from the left to navigate to Brightness. Then use the +/- Adjustment buttons to change the brightness.

Unfortunately, this may be a symptom of a failing backlight (if you can see a dim image). These are sandwiched on the perimeter of the TV (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your TV size. Separate the panel from the bezel. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything. For more information, seehttp://www.lcdparts.net/howto/default.aspx but for an overview: http://www.inventgeek.com/Projects/BacklightFix/overview.aspx Then push the new backlights into place, reconnect the wires and close up the sandwich of tape and other parts around the screen. Then replace it in the bezel.

With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight. Usually if the inverter fails, you will not see any image on the screen. However the inverter is easier to check or replace. For an out-of-warranty TV, open up the back of the TV and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.) The scorch mark and smoke may indicate a resistor or zener diode that had been used as a fuse and is now gone.

If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the inverter board and power up the TV. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.

In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one (shopjimmy.com or lcdparts.net are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.

I hope this helps.

Power supply section will be the first place to check.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Once you're ruled out your PC and video card by trying a different monitor, I would suspect the problem is a bad video / signal board inside the monitor. If so, it needs component-level electronic troubleshooting to locate the bad part(s).

One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.

what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.

CAT6 cables & jacks are better than CAT5E.
CAT5E cables & jacks are better than CAT5.
CAT5 cables & jacks are better than CAT3.
CAT3 cables have problems going faster than 10Mbit/second.
CAT5 cables support 100Mbit/second, and seem to work with 1000Mbit/second ("gigabit") devices.

IF they are new, get a replacement, the wires in those are very small and subject to breaking. IF you cannot return them, get another set.

You will need the sort code, account number and name of the account holder. If you are doing it online you need to go to your bank account details and look for payments to individuals or companies.
