Replacing Capacitor on LCD Monitor

I wanted to know if replacing a 470uf 25v capacitor for a 470uf 35v on a LCD Monitor would be fine. Someone said it was fine as long as you're replacing it for higher voltage. I just want to make sure before I do that. thanks.

first you can test the voltage of the multr,and then check which part is defective.From can find those parts
if you have any question,please let us know,we sincerely hope we can help you!

Re: Replacing Capacitor on LCD Monitor

That is good advice. Always replace with same or higher voltage rating. Also make sure it is put in the right way around.

Samsung Monitor Backlight/Power Issue

hi, these mosfets are obsolete now, do you know a good equivalent for them?

Power Light blinks on then shuts down - Black Screen

I couldn't find any fix on this monitor so I had to go it alone.......

My VG500b monitor would power on then the power light would blink off. there was no display at all but I could see the LCD panel change in brightness just a small bit during the power on and then power off. I found that there was a bad capacitor on the inverter board. I replaced the 47uF 25v capacitor with a 47uF 35v capacitor. (The 25v would be okay but I always replace a failed capcitor with a higher voltage rating) This capacitor is the shorter form in order to fit under the shield. You can use a taller capaitor but you will have to lay it down, as in bend the leads down and lay it on it's side in order to fit under the sheld when you put it back together. VG500b fired right up and is going strong once again. Hope this helps someone.

I have a Samsung Syncmaster 932b LCD monitor. When I turn it on, the screen just flashes on and off, as does the blue light around the power button. I read up online and found that the capacitors on the...

savato321, Most black screen lcd monitor owners don't have the smarts to open up their monitors to do a VISUAL inspection of the "switch-mode-power-supply/inverter supply!!!! You're good. Now you will need to know some stuff about electrolytic filter capacitors! First, the "uf" or "UF" means micro-farad! It is just a rating given to express the storage capacity of the device. Next is the voltage rating. A 16v rating means that the capacitor should never be placed in a circuit where the voltage will exceed 10 to 12 volts DC. Your 820 uf cap rated at 25volts will most likely be in a 12 to 18volt dc circuit. Now for temperature rating. All caps have a maximum temp rating. Most clock radios, stereos, will use 85 degree centegrade rated caps. Printers,PCs,monitors, will use 105 degree C rated capacitors. Never replace with lower specification units! You can GO up but never DOWN. If 1000uf 25v is all you can get it's OK. If you can get 820uf 35v units and they are not too big and they will fit on the board sure you can use them. I would stick with the OEM design voltage rating. Electrolytic CAPS are polarized!! You must replace them + to + and - to -!!! If you screw -up they will blow-up!! The wire lead closest to the printed STRIPE on the cap will be the negative and the unmarked terminal will be the positive. If you visit you will get more info on recapping your SMPS. You can also watch some DIY videos at YOUTUBE for "lcd monitor repair" that might be helpful. Also visually inspect the SMPS/inverter printed circuit board for "COLD" FROSTY looking solder joints. They should all have near mirror finish to them. Let us know the name of the BAD CAPS you remove from your unit. You may even want to document with pics with a digital camera what you find. Well, good luck guy. 12fixlouie

LCD goes black after few minutes

I would suspect the capacitors on the power supply board. Other sites show that power up problems are due to the aluminum electrolytic capacitors on the power supply board being defective. Replacing the four 470uf 25v capacitors (470 micro farad, 25 volt) on the board usually fixes the problem. Sometimes also the two 1200uf 25v capacitors could be the culprit. I suggest changing them all. The price is about $7 for the parts online at Mouser electronics plus $7 shipping. I just fixed mine. I bought two 1200uf 35v capacitors, Mouser part number: 647-UPJ1V122MHD6 and four 470uf 25v capacitors Mouser part number: 661-EKY250ELL471MH2 These are slightly larger than the originals but still fit and they were in stock. You will then have to open the unit (relatively easy) remove the power supply board by removing four screws and disconnecting the connectors (Make a note of wire colors and where the connectors came from before removing). Then you will need to remove the old parts by desoldering them and then solder in the new parts (somewhat easy if you have soldered before)

When i switch on my P.C. and my FP 5313 screen it flickers

This is a known problem with a series of components inside the monitor. There are about 11 capacitors that if replaced will allow the monitor to function properly.

The best place to go to

The list of the capacitors that are bad are below with possible replacements.

C922, C925: Hermei LE 1000uF 16V, low impedance, general purpose, replacing with 1000uF 16V Samxon GF.
C201: Hermei LZ 150uF 25V, ultra low impedance, high ripple current, replacing with 1000uF 25V Samxon GF.
C924, C926, C929, C930, C932, C933: Hermei LT 470uF 16V, high ripple current, low impedance, replacing with 1000uF 16V Samxon GF.
C207: Unknown CD110 50uF 4.7uF (general purpose), replacing with a 35V 4.7uF tantalum unit (SCP/Short Circuit Protection pin on TL1451 won't get anywhere near 35V).
C907: WC (with stylized Westinghouse W) SM 22uF 50V (general purpose), replacing with 63V 100uF Samxon GF (used for SMPS controller Vcc filtering).
C905: Hermei HT 100uF 400V, standard, general purpose, leaving as is - generally no problem.

Can changing 3 capacitors on motherboard solve my problem?

We had a power surge and my VL2018W LCD monitor stopped working... blank screen and flashing blue light.

I carefully opened up the back and found the power board (the one the AC plug goes into). There were about 5 electrolytic capacitors that were bulging (but not ruptured). There were 3 with the values listed by the original poster (470uF @ 25V) and 2 with 1000uF @ 10V.

I scrounged a couple of 2200uF@10V caps for the last two and bought 3 470uF @ 35V caps from Radio Shack (P/N 272-1030).

Luckily, the monitor came right back up and seems to be OK. It was out of warranty, so there wasn't a big risk.

Just increasing the working voltage won't do that much for you. If any caps are bad, just replacing them with the same value is good enough, but a higher working voltage won't hurt (usually means a bigger cap).

Good luck.

I replaced the 470uf 25v capicitors and this fixed the problem. I had 2 monitors exactly same with the same problem and it fixed both of them.

Monitor Powers off after a second or two.........

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Bad power board Planar PL2010M

There is a supplier of power boards online, you can google them with numbers from the board but I don't suggest using them. Look for information on the company also. I've seen a lot of complaints for this "international" company.

The fix for most of the problems on these monitors is about $8 on new capacitors (Plus shipping).

First check that you are getting a strong 12V from the external power adapter. If so, the problems may be as simple as changing out a few capacitors.

On the PL2010M monitors you need the following parts. I've added digikey part numbers to make life easier:

P10271-ND 220UF 25V Capacitor (3 or 4 depending on PS)
P10275-ND 470UF 25V Capacitor (1)
P10221-ND 470UF 10V Capacitor (4)

If you're not comfortable with soldering and de-soldering electronics, take it to a local technitian for the work and give them the parts list above. That should work to fix your issues. I've fixed several of these monitors so far. All the problems were related to the power supplies having bad capacitors. Same with the Planar PL1700 LCD monitors.

Good luck!

Monitor Blinking

hello guys

I had the same problem. My LCD ViewSonic VX 924 has been blinking

For repar it i changed the following capacitors : 100uF/400v
330uF/25v and 330uF/35v

if that always flickers you can also change the two 470uF/25v capacitors
