    I have a ProView flat panel also. It had a beautiful picture one minute and the next time I looked up everything was blue. I turned it off and on again and now I have a grid pattern that seems to be missing parts of the picture where the lines on the grid are.

    Any suggestions?

Dear Fixya Team, I have a problem in my LG flatron F700B 17 inch CRT monitor. My monitor was connected to an external TV card. The adapter of the TV card was defective and my brother plugged in the direct...


The "IC" (Integrated Circuit but often called a "chip") you have been told to be the problem, is a generic diagnosis. There are dozens (or more) of IC's in modern electronic appliances - including your monitor. ICs are what has allowed electronics to become miniaturized as they combine the functions of one or more circuits that may have needed large, bulky, heat producing vacuum tubes to something before that now is the size of a pin head. They look like these:

Drawing of the inside of an I.C. Actual I.C.

ICs come in all sorts of sizes and perform all sorts of different functions. Some are very common and cost significantly less than a dollar, while others are very specialized and cost hundreds or of dollars or more.

Since the power indicator of the monitor is lit, some or all of the power supply circuits are OK. Unfortunately, there are a great deal more circuits inside the monitor - one or more of which have failed.

Your repairer may have not even bothered to diagnose which IC had failed as the prices of monitors have been falling for so long, many people simply replace them with new, thin screen devices instead. If you wish to attempt the repair yourself, you should ask the repairer *which* IC has failed and then obtain it yourself to for replacement. Without the required knowledge and test equipment, knowing which IC to replace will be impossible to determine.

This is only an overview of the problem your monitor has. You will probably find that repairing the monitor is too time consuming and / or parts and other information about it are too costly or difficult to locate - or both. Good luck to you.

I have a proview lcd monitor model pl866s .What is the size of the power connector for the 19vdc @3068a psu?I have an extra psu with the correct voltage /current .Thanks Robert.


For the above LCD Monitor, I actually saw a small spark at the top part of the main board once the power input jack was connected. It prompted me to the exact location and when I check the SMD ceramic capacitor (that generated the spark underneath it) with analog meter set to X 10 K ohm range; it actually developed a slight short circuit. Replacing only the fuse and the SMD ceramic capacitor solved the no power problem in this 19" LCD Monitor. This Monitor uses the inverter IC (OZ960G), A1084-25CM (2.5 volts voltage regulator), AMC1117-3.3 (3.3 volts voltage regulator), ADC IC (MST8136B) and CPU IC (MYSON MTV312MV64).

TV turns on for about 5 minutes the the picture cuts out but sound stays on. Its a Proview 19 inch LCD TV


mrhackshack, Part of "switch-mode-power-supply" is going into SHUTDOWN mode having detected FAULT with other circuit (INVERTER) maybe???? Inverter lights-up the "cold-cathode-fluorescent-lamps" that provide RAW WHITE LIGHT so you can see all the pretty colors on the LCD GLASS PANEL. Technician will need to evaluate it!! Try YOUTUBE for vids on LCD TV repair and see if you can pull-off a DIY repair. Also see vids of LCD monitor repair and LCD monitor disassembly FYI. 12fixlouie Hope this points you in direction you need to go?????

Proview 15" screen turns white


probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver ic thus you could only see white display. A replacement of LCD panel is the best solution. I suggest to bring it to an authorized service center. best regards

Colored lines on screen


This may be caused by the death of a display driver circuit and these might be integrated with the display itself. 
The pixels on the screen are controlled by an X-Y matrix and the matrix may have signal lines that are somewhat shared for different screen positions.
I doubt that this is DIY project and the failure can only be located by an equipped and trained tech.

I would change the caps anyway, they're cheap. The IC's may be running hot trying to make up for the bad caps.
