You need to get/buy/download the service manual and
schematics, so you can then trace and analyze the circuit.

A strong knowledge of electronics is required to do this.

Analysis is complicated by the fact that all key functions
within the monitor are controlled by software running on
undocumented digital control chips. The chips are called
ASICs, or application specific integrated circuits, custom
designed for the manufacturer, and programmed with secret
software.

Beyond obvious voltage and continuity checks outside
of these chips, there is little to analyze or repair in a modern
electronic appliance.

There is no magic solution nor red and green "what chu mah
callit to replace"

I have thirty years in electronics and a degree in computer
electronics, yet I stopped fixing monitors years ago.
There is no percentage in it.

I just bought 4 x 21" hi-resolution wide screen monitors,
with 5 Millisecond pixel time constants and 1000:1 contrast
ration for $180 each,

and sold of my 3 year old monitors for 15 bucks each at
a garage sale.

Hi, monitor is HP vs19c less than 2 yrs old. One


Your monitor probably has roasted capacitors. And your warranty is probably passed. Happens to a lot of different brands too. The capacitors are cheap, and not too hard to replace if you posess the soldering tools and skills. If you can't do it yourself, finding a shop to do the work can be tough, and may be pricey. Some opt to sell on ebay and just get another monitor.

I have same problem despite truning off screen saver and setting power options to NEVER SLEEP! I have same dell monitor, running wondows vista basic in dell vostro! anyone with a solution. this PC is less...


If the problems happens on another computer then call dell to get the problem resolved. You could also go into the system setup by pressing F2 when the computer loads up and see if it happens in their, or you can also put the known good monitor in your system and it you get the same problem the problem is with the computer and the issue is either a hardware or software issue. If the problem happens in the system setup or during the diagnostics then the issue is hardware. Please call dell tech support if you find out the issue is points to the monitor and we would be glad to replace the monitor, if the monitor is not tied to the system(not in the order details or was purchased later) then the monitor has a 3 year warranty, if the monitor was purchased with the system , the warranty is the same as the system or if that warranty more than 3 years than the warranty for the monitor is still only 3 years. Thanks and please reply back if you still need assistance.

I need a replacement power cord



Found one here:
http://acebargains.stores.yahoo.net/acpoadforwel.html

and ebay looks to have a few as well:

http://cgi.ebay.com/AC-power-adapter-Westinghouse-LCM-17V2-sl--LCD-monitor_W0QQitemZ360118562836QQcmdZViewItem

Hope this helps. You are right this far from a typical power supply cord. Most just need to the cord with a 3 hole female end that plugs straight in the monitor.

I bought a Frigidare refrigerator today. Warranty needed?


its really just up to you. I am a service tech in grants pass oregon and i know compressors dont last anymore. Its because in the last 10 years they have switched from r12 freon to 134a. 134a has higher head pressures which make the compressor go out. If the compressor warranty isnt too much money i would do that warranty. You dont really need the others.

Faulty monitor after one year


Hi Shirley,

In Singapore, Acer monitor is 3 years warranty.

If the your monitor is out-of-warranty, please consider replacing. It is cheaper than repair.

Performance life is normally around 2.5 yrs ++. Normal faults is due to manufacturing defects.

No power to 1801fp


Less than 5 bucks. Also look at the inverter board, and underneath the board it goes to Yup, common as dirt inverter could be swapped in, or - You could cut off a +12volt and +5 volt lead/connector for disk drives from a dud power supply , drill a hole, and power it externally from any **** no name power supply. Of course, replacing all electros under 100uf may get you going for under a dollar. Canberra

Dell P780 17" CRT Monitor(3 yrs old) issue


That sounds like a monitor issue, not a video card. Gradual fading means components within the monitor are wearing out. However, I strongly advice against attempting repairs. CRT monitors hold a strong electrical charge. People have been injured and even killed by attempting to work on them without proper tools and training. A 17" CRT monitor is too cheap to be worth the risk (you can often get them used... I got mine for $20 at Goodwill).
