Fisher tv monitor intermittently turns to snow and loud buzzing

Fisher Standard TV is about 20-25 years old. Intermittently picture turns to snow with loud hissing sound. Usually after a few seconds it clears up and picture and sound come back. Other times, turning it off and back on with the remote clears it up...and sometimes have to turn it off and try later.

I'd say about the blinking to a black screen would be your cable provider. As for the stripes that means that your board panels can be going bad, you can try updating the firmware of the TV to help but if that doesn't work you're getting very close to full failure on the TV.

It seems that it is a hardware issue with the monitor, as it does the same thing with different PC. You can check the VGA cable going on the back of the Monitor as it may have a loose connection. It may be due to the connector, which is not getting placed properly, you can try changing the monitor VGA cable. OR need to send it for repair, but repair will cost around $50+, you may get another monitor by adding a little more to ie.

My HP w1907 monitor less than a year old is turning pink!


A flickering screen with pink colour is a sign of a CCFL lamp problem.
The CCFL lamp is a mini fluro tube and it provides the back-lighting, it is definitely faulty and about to fail completely.
You need to get it repaired while it is still under warranty.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way.

I hope this helps, if so please rate my solution.

ViewSonic 19" flat screen monitor goes black - intermittently


Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,

Connected to "Y"? That is for the rgb cables for a high def connection method. You need to find the video in connection plug, usually yellow to get a color picture for the games. Hope this helps.

NEC P1250+ hisses and scrren blips intermittently


I had the same problem. Your monitor is warning you of failure. The hissing sound is the picture tube powering up. The momentary blank screen is when the power supply for the monitor has become hot. Your monitor is getting ready to quit. My suggestion is to buy a new monitor. To have a tech repair it would be more expensive then buying a new one.
