Question about RCA HDLP50W151 50" Rear Projection HDTV

1 Answer

Hd50lpw175x7 I made sure to check to make sure they have same polarity up and same uf rating. I know I'm not very electrical sound but what do you mean by unsolder and solder? j

The capacitors are solderd into the circuit board so you have to melt the solder with a solder Iron to remove the legs of the capacitors from the circuit. Then you have to install the new capacitors in the same pin holes and resolder the legs. Be sure that the negative side of the capacitor goes back in the correct hole like the old one was.

Anyone who know what is the size of 2 big capacitors on the board of R92U-LD3 ,256MB D33053 ATI AGP graphic card


First.
By the "size" you refer to... I assume you mean the Value's of the Capacitor.
These are written on the Capacitor as Voltage and uF.
The "size" of an Electrolytic Capacitor depends on the voltage & micro farads(uF) it is storing. (Like a Battery)
You can always add more uF and the voltage rating can be more (but not less).
Does the Cap have signs of leakage around the leads or does it have a Bulge in the top of the can. If so, it's probably bad.
The Electrolytic Cap's wires are marked positive & negative. (Negative is marked down one side).
Do not swap the polarity + - of the cap or it can blow.

The Radeon Graphics Card in a computer would run on probably 5v for logic for circuit boards & 12v for hard drives etc. No more than 12v DC max. So you can replace with a 16v replacement electrolytic Cap. But would be easy to check across the Cap with a voltmeter to find out.
Always buy a Cap with slightly higher voltage rating than the circuit it is going in to.
If it's large and attached to the main power input then it will probably be around 1000uf to 2000uf. The voltage and uF are written on the Cap body.
You can't hurt the electronics (in a power supply circuit) by adding more Capacitance.
Large Electrolytic Cap's are used to remove noise ripple from the power supply. They smooth it out. More Capacity = less ripple.
Because Electrolytic Cap's usually fail as open circuit and loose capacitance it's easy to attach another Cap in Parallel over the bad one. If so...
For troubleshooting purposes, you can leave the current Cap in place and attache a couple of wires of say 1-2 inches. Use coloured wire to keep the polarity correct. Attach 1000uf 16v Cap to wire ends and run the device to see if it's working OK.
Hope all this Helps

Bose 20 display failed


Older Bose Lifestyle systems are prone to electrolytic capacitor failures. Replace all electrolytic capacitors on the main control board with identical uF value, equal or greater voltage rating, equal or greater temp rating. There are about a dozen on the board with at 2-3 different values. Disassembly and reassembly is straight forward. Those with capable skills in mechanical and electrical areas should find the project will take about 1-2 hours. I recommend grounding the board when working on it. Find a spot on the board where the ground is marked, and attach a jumper to a ground point. Take caution during the disassembly -- take photos, lots of plastic parts, etc. The eCaps are polarized, so be sure to check polarity as you unsolder, and install new eCaps with same polarity (+ & - ) as the old.

Once caps are replaced the voltage levels to correctly operate the display will be back to factory settings, and the display should show brightly. Good Luck!

I just want to know what the designation 216/259 means and if it is a non-polarized electrolytic capacitor. This is to increase my general knowledge.


generally electrolytic capacitor is polarized..and if im n0t wrong 216-259 stand for tollerance microfarad- uf and 110-125 stand for tollerance volts-v pls check for the symbols on that capacitor

I have a 9-inch drill press and the motor capacitor is smoking is there a replecment part for that or where can I buy one


you should be able to go to any electrical supply house and with the old capacitor they can match it up for you, check in your phone book for electric motors repair and you should find one. If not let me know the area you are in with your zip code and I will see what I can do.

No display flashing power button


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 www.ccl-la.com/badcaps.htm 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

Buzzing in TV is from part sdt sh 112dm. will changing the part quiet the buzz?


C622 is the real problem. It is a 470 uf capacitor filtering the power to the blue relay. Radio Shack sells it for $1.29 part number 272-1030. make sure you observe polarity when you replace it. In other words, the side marked minus goes on the negative side. Check the markings on the old capacitor and replace it the same way with new one. The new capacitor has a higher voltage rating which is even better.

the clicking is the relay -- check the fuses on the supply board and you might need to purchase a new board

You have to unsolder the old capacitors and then solder in the new capacitors. You have to make sure to observe the correct polarity and install the new ones the same way as the old ones one side is marked negative dont mix them up do one at a time and notice which side is marked negative on the old one and install the new one the same way. also make sure they have the same uf ratings as the old ones.

The SDT-SH-112DM is a SPST Form-1A relay. It was hard to find, so I went to Radio Shack and bought a similarly sized and rated relay that was a DPDT (also from OEG). broke off the NC pins, joined (soldered) the switch source lines & removed the unused NO pin so it would fit in the drill holes... works fine!
