Question about HP Pavilion M70 17" CRT Monitor

White Sharp Horizontal Streak on Center Screen

Started noticing the problem in Subject. Opened the Monitor Cover & found, if I lift up and hold the Circuit Board corner near the Screen Focus / Brightness Adj. control, the display is back to normal. I suspect a Dry solder / Broken Solder contact. Do not exactly know which point to re-solder. If anyone know which point(s) to re-solder it would be great. Otherwise I need to re-solder all the contacts in that corner/area of the Circuit board.

Re: White Sharp Horizontal Streak on Center Screen

Hello RepairKid,

Although it's difficult to pinpoint which solder point(s) are the cause of a problem of this nature, the use of a magnifying glass will help you determine which solder point(s) look "irregular" compared to the other ones. Look for cracks or pits across the solder point and re-solder once found. Sometimes a hairline of solder is shorting out two points and again is might not be possible possible to see without magnification. If you don't notice any irregular solder points, a component could be causing the problem (like a very dirty/oxidized potentiometer or a cracked discrete / SMD). Let me know if this helps.

LG L222WS half bottom screen white

There is a problem with the capacitors in your monitor. This is a normal problem these days with flat screen monitors, I am trying to find out why it is always like tha. This will normally be caused by improper shut down or power fluctuations in your monitor. Capacitrs in your monitor are responsible for holding down the power from the supply, fr the proper display on your monitor. If a capacitor is damaged, or buldged, it no longer holds power long enough for your display, and that is why your screen goes black after a few seconds. This can be solved by opening up your monitor, using a sharp and flat object, opening it starting from the bottom working your way up until the cover is completely out. You will notice finger-like clips that are holding the two covers together. Once you are done, check on the circut board where you connect the power cable.... that is where you are going to find the damaged capacitor(s). You can identify them by noting their bulged head or if there is any liquid coming out of it. Before you replace the, take note of the polarity (+) and (-) so that whenever you replace with the new one it is in the same direction. This will fix up your problem. Note: make sure you let a Computer Technician to do this for you, unless you can do it yourself without damaging the monitor. Thank you

245BW Snap/Crack sound and then does not work

Be very careful! Some monitors/TV's have 30,000+ volts DC in them even when not plugged into AC house current. The crack/snap sound was most likely an electrical component breaking down and shorting against the metal of the case of the monitor. I would take the monitor to an authorized repair center because the danger of getting shocked/killed is very possible while working on this type of problem at home.

Sure it can be fixed, I think some components on the main board needs resolder on their soldered joints. Try this first before thinkig of getting a new one.

Proview PL926Wbi LCD Monitor White Screen

I found in the refuse, a Gateway FPD 1520, 15" LCD monitor that started off losing the screen half-way, losing sync, etc. The "mechanical agitation" method was applied and remedied the problem. Awhile ago, it went to a white screen (or, as it was back in the day- a clean raster). I opened it up and found that the ribbon cable on the left was loose. I applied a series of layers of adhesive-backed foam (the kind you stop drafts in your home with) until it was greater than the height of the metal enclosure to put pressure on the unbehaving connector. It does seem a bit loose and this will keep it snug. Maybe hot glue or other adhesive if it wiggles loose again. Seems to have solved the problem at the moment.

Brown horizontal lines sporadically appearing on monitor

I have exactly the same problem with the identical monitor, but I have not found any solution. It seems to be the monitor causing it because I can't see the lines, when I make a screen dump.
