An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

Just to be a little more detailed, since I just fixed this problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

I have a Proscan plded3992a . When the TV cuts on you can see and hear everything, currently via hdmi. The screen however is dim. Still visible and blinks steadily to normal brightness.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The power light blinks blue, no screen, unable to turn on or off.


Hi Lewis,
Your tv needs to be checked by a TV tech. There is nothing you can do about it unless you are handy with electronic repairs.

Pictures keeps going out


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.

Why does my HP vs17 monitor screen keep going to blank black screen like it turned off but did'nt.....blue power button light is still on? Everything is running but no picture.....keeps happening everytime...


this old monitor has 2 issues.
1: it has CCFL tubes that love to burn out (backlamps)
most this old are long go, yell,dim.,blinking or DEAD.
2: push the menu button on front of mon. turn off power saver.

3: if the PC goes to sleep, or hibernete mode (parked)
then that is 100% normal
if you dont like feature then go to windows control panel
click power, ICON and turn off all monitor sleep /hibernate modes.

that assumes windows, no OS stated.


if the lamps are dead,
use flash light pointed to sceen, see data. ? bingo for bad CCFT tubes.
as seen here

I have model 1975NW. When power is turned on, green light appears, then orange light. No picture is present.


The ORANGE light indicates "power-saving" mode -- when no "output" from a video-card is being detected, the screen will dim itself. Try a different monitor. Try a different video-card in your computer. Try your monitor on a different computer.
