My husband is at radio shack now looking for the caps for our polaroid tv the salesperson dos not know what that looks like can you help?


The caps are electrolytic 1000uf (microfarad) 10 volt capacitors. I tried to get them at the radioshack locally and they didn't carry any smaller than 35 volt. I didn't want take the risk so I ordered them from this site. Try it if you can't find them locally.

A very common problem with that unit is the power supply. You could probably open the rear case yourself and locate the power supply module. Look for the electrolytic caps EC18, 19, 20 all are 1000uf/16v Then EC9, 10 which is 1000uf/35v and EC14, 25 both 470uf/35v Replace these and you should resolve the problem. If you have some basic soldering experience and be patient it's not a difficult repair. Just make sure that you get the new cap placed in the same manner, they are polorized, having a positive and negative side.
You'll need some solder, desoldering braid and a GOOD soldering station or stick. Most of this, including the caps you can get at ACME sales in Florida.
Good Luck!

37"polaroid FLM-373B


Hey guys, I read the solution about replacing the 10v 1000muf caps in the power supply module. I was ready to throw the set out. I tore apart an old old old Jerrold 700 converter and found a couple of caps that were 1000muf. One was 26v and the other was 52v. Anyway, the set works great now and I now have a 37" LCD in my shop to watch the Leafs!!!!
Thanks for the advice.

Same problem


If you don't have real good soldering skill I would advise you don't try it. they are hard to change and have to be put in in a particular direction "polarity" one wrong thing and you will smoke the board. But if you try ... any electronic parts supply has the caps ie Radio Shack

Yes, I am a computer / electronics person and by brother's tv had the same problem, here is a complete description of the problem and the fix. Many thanks to all that have come before

Symptoms

1) While watching tv, there will be vertical grayish lines that move around a bit on the screen
2) While viewing a menu, the menu will be all hacked up as if the bits are all out of order
3) If you unplug all of the sources and then re-power the tv, unplug from wall, the tv will seem it is working fine. Menus will work until a video source (Component) is plugged into the tv.

Tacking the back off

WITH TWO PEOPLE Lay the TV on a table with a blanket, etc to protect the tv. Do not try and move the TV with the back off in general. You may flex the screen and damage it.

Remove all of the screws from the back including the one under the sticker near the left bottom. Remove the stand from the bottom. Lift the back up from the left to the right. Power is hooked to the right of the back. Remove the two screws to remove the power jack from the back.

Remove the back and place aside

Remove the RF cover from and the board will be underneath

Remove all of the screws from the board and from the RCA connectors from the outside bottom of the board.

Carefully remove all of the wires, taking time to remove the glue from the connectors. The glue should "Snap Off", take your time here. Remove the wires, noting where they all are. Take your time with the big connector on the left side.

You will see that all / some of the caps will have a discoloration on the bottom.

Replace and replace ALL of the caps on the upper left side of the board. It's OK to replace with a higher value Voltage, they must be the same uf value of equal or higher voltage. They must be electrolytic caps (+/-). Make sure the line up the - properly with replacing. Radio shack may not have all of the them, but other electronics supply place should. They are call fairly common.

If you have never done this before, find someone that has, or find another tutorial on how to do this. You will need a small soldering iron and solder ****** and very thin solder from Radio Shack.

Replace the board, we tested by putting the board back. Sliding the TV on a table so the top could be seen and then plugging a source in and verifying it worked before reassembly. You HAVE to have a component source plugged in or it will false positive the test. We found this out the hard way....

Replace the back and the screws. On the right side of the TV MAKE SURE that the AC power wires are NOT in the way the screws on the right hand side.

Replace the TV to the original position and test....

Reason for Problem.

Either they have a flaw in the design, but more probably they had a poor supplier of the Capacitors. I have seen this before and we will probably see it again. This really should be some sort of class action suit since they are all failing about 1.5 years of use.

Any question, please contact me....

Akai lct3201 power problem


I fixed my Akai LCT3201AD in about 30mins. using 3 small parts from Radio Shack. Once I got the back off, I found the power supply board (PSB), mine was part# MLT-169B rev1.2. I looked at the capacitors (caps.) first, because they are usually easy to diagnose. I noticed the caps. bubbled out on the top of the board (where all the cables connect to it). There is 3 of them in a row, positioned between the two large heatsinks. My guess is that the heatsinks are generating a LOT of heat over time, because of bad ventilation, and causing the caps. to fail.
I went to Radio Shack and found 3 caps. (only had 3 in stock). The original ones were 16V-1000uF, Radio Shack only carried 35V and 50V in the 1000uF caps., so I bought the 35V ones and headed home, I removed the old caps. from the board, and installed the new ones. The 35V caps, are a little bigger, so its a tighter fit on the board, be careful. It took longer to remove the back from the TV than it did to do the soldering. YouTube.com has excellent videos on how to de-solder caps. on PSB's.

Total money spent on repairs:
$1.59 ea for 3 Caps. (part# 272-1032) $4.77
$2.99 for new soldering iron tip + $2.99
$1.00 donation for St. Jude's + $1.00
Total including tax $9.30


So for less than $10, I did a repair that my local TV repair shop wanted $575 for. Online stores want anywhere from $100-$275 for a PSB. If I get another 2 yrs out of it that's well worth $10.
