Question about HP Pavilion F1703 17" LCD Monitor

Open Question

HP Monitor Hello. I am sorry to bother you, however, you posted the comments : ---- I have repaired at least 50 of these monitors. It is a result of cold solder joints on toroidal coils. Since you have to take it apart to resolder the toroids replace the four push-pull transistors that drive the output transformers, they only cost about a dollar each. They fail on overheat and shut down the inverter. I have never had any of these monitors fail again after correcting these 2 issues. ---- I was wondering if you could tell me where I would purchase these transformers that are a dollar a piece. My screen is doing the same and I would rather replace than resolder. My email address is Thank you in advance.

SOURCE: Monitor repair

look in your local paper for monitor repairer,
but as the cost of a new monitors has come down so much ,i would consider a new purchase as the refresh rates and picture quality are far better now than when your monitor was produced,also second hand prices are very low .

good luck

SOURCE: What are the toroidal coils?

On my monitor I had the 8 pin smt FET's short out. The CCFL transformers were not bad. You can use a ohm meter to determine if the transistors are shorted or open. If you use FET's like mine did, you can monitor the out put for voltage. Mine was 12 volts pulsed DC. Good luck.

SOURCE: Screen flickers, turns on and off

Normally this kind of problem needs only the dry soder, cause theres some loose components some where on the main board. Try to resolder any visiual suspicious terminals of components.Try to see carefully if any of the capacitor has any buldgy appearence on top of them. If there is try replacing them.cheers

The picture board on your monitor is malfunctioning, since the power led or button is on and it randomly stop the dispaly signals, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

If your like me you probably have another computer around. We need to "Borrow" its monitor. If not see if a friend of yours has one you can use for a day.

Replace your monitor with the "Borrowed" one and fire it up. If you get the black out right away, try the previous tip with this monitor as well. If this Monitor works, then we have determined that YOUR Monitor has (In gaming terms) "Been fragged". If its an older Monitor its entirely possible that running L4D at max resolution might have been just enough to push it to failure.

If the "Borrowed" Monitor exhibits the same symptoms even after the test. Then the blame lies on your Video card.

Whichever one failed check to see if its under warranty (Not likely for the monitor unless it's less than a year old) But for the video card, if it's by a bigname manufacturer (ie... PNY,BFG, ASUS etc...) then try to scare up your documentation and receipt because alot of these companies offer a Lifetime warranty and you'll get your card replaced/repaired for free. Sometimes if its a discontinued model you even get a free "Upgrade"

If you don't have a warranty. Get a service quote. Find a place that'll give you a free estimate. If you can't find a quote for less than half the cost of purchasing a NEW replacement, then your better of getting a new one. because you'll benefit from "New" technology AND you'll get a warranty with it.

Sorry for the bad news
Hope this helps

Fujitsu c series labtop screen goes blank, the hooked up to a monitor, starts to work then says out of frequence and goes blank

The video resolution and/or frequency that's set in windows is not supported by the monitor you have plugged in. Restart the PC in VGA mode (hit F8 after the BIOS messages but before any Windows messages) and change the video settings to something basic, such as 800 x 600 @ 60 Hz. Then restart the machine normally.

Regarding L1515S 15" LCD Monitor Resolution

Hello mallik, The LCD monitor is actually a active matrix of small transistors (3 for each pixel). They have one native resolution, a FIXED one for example you monitor has 1024 x 768 pixels. This results in 786432 pixels displayed on the screen. Because each pixel is controlled by 3 transistors there will be 2359296 transistors controlling your entire screen. This is a fix number. You can't raise the resolution to 1280 x 1024 because this will require as you can see now... a lot more transistors on the same surface. All you can do is to lower the resolution, in this case 4 pixels (12 transistors) form a larger pixel acording to that lower resolution. The image can look blurry in these situations. THe bottom ideea is that a LCD pannel (more corectly said, TFT (thin transistor film) pannel, has one optimum resolution, it's native one. The higher the better, when choosing one to buy, but you can't raise the resolution over that. You can just lower it. It works different then the normal conventional CRT monitors. Sorry for my bad english as I live in a non english-speaking country. Also if you have anymore questions please post a comment.
