    I appreciate the info. Sorry about your tv crashing again but I'm going to try this anyway. Let me know how the power board works since that may be my next move. Thanks

Well there were the (2) from this original solution:
http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen
And I replaced a third that was right by these two. However now my TV has died again. I just bought a new power board and will install tonight (like $120.00). It looks like this is my only option...I'll advise if this fixes our problem. If not I'm chunking it!!!

Olevia 242 S11, began having sound issues; first turned on pic with no sound. Cycle 2-3 times sound would return. Now it would not turn on. Would have to unplug power for 5 min. HELP


That sounds very much like a failed electrolytic capacitor in the power supply board. It's easy to spot; the top of the capacitor is bulged up and may be leaking material. Usually, there is more than one bad capacitor. See the attached photo - two of the three capacitors shown are bad.
https://s17-us2.ixquick.com/cgi-bin/serveimage?

To get replacements, you need the following information: Capacitance, printed on the capacitor label (e. g., 2200 uF where the u is actually the Greek letter mu and stands for micro-; this would mean 2200 microFarads),
Maximum Voltage, printed on the capacitor. The replacement may have a higher voltage rating, but not lower.
Maximum temperature, printed on the capacitor. The replacement may have a higher temperature rating, but not lower.
Diameter of the capacitor in millimeters. The replacement may have a smaller diameter, but smaller diameter capacitors may not meet ripple current or endurance specs (described later). There may not be enough space on the board at that location for larger diameters.
Length of capacitor in millimeters. If it is too long, you won't be able to fit the cover back on without damaging something.
Endurance: at least 6000 hours at maximum temperature. For 10 mm diameter capacitors or larger, you should be able to find 10,000 hour parts.
Ripple current: You want the maximum ripple current rating available consistent with the other specs, otherwise the new capacitor may burn out prematurely. Higher voltage capacitors often have a greater ripple current rating, and physically larger capacitors likewise.

I have had excellent result with Panasonic FR series capacitors. They are much better than the Chinese off-brands usually installed in LCD TVs. When you install the replacement capacitor, make sure the polarity band goes in the same way as the original (the board is probably marked to show which way), and use lead-free electronic solder with an iron that gets hot enough for it. There are static-sensitive parts on the power supply board. Do not touch the circuit conductors with your fingers; handle the board by the edges only. Do not place the board with the wiring side down on any surface except an antistatic mat.

I would replace the entire inverter board. Picking and choosing will cost more.

Replaced 3 capacitors for start up issue, now have radom with vertical lines


You will need to replace all the capacitors in the output side of the power supply. It is possible you have other bad capacitors that are not bulging at the tops. The power supply generates a voltage used by the the video processor on the main board. If this voltage is out of whack, it can affect your video. I would recommend you check all power supply voltages for accuracy and ripple.

TV comes on, but, no picture, no sound


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

I think our TV is around five years old now. Over the last year we have had the same problems about four times the last three this year. It just turns its self off. The red light is left flickering for a...


hi there, hope this helps. Why not try to replace the filter capacitor in the secondary section. you said you have it repaired before and now the same problem happens. sometimes we should replace the capacitor for this is usually the cause of defects in the power supply. In long usage of capacitors it becomes leaky that results to insufficient power output. you can see the defects visually (sometimes it become bulgy) unless you use the capacitance tester. having it replaced can surely extend the life span of your TV. if you're not sure which one is the leaky one try to replace most of the capacitor especially the big ones. like I said replacing any of them can enhance for better performance of the unit.
Good day, please rate and vote.

power board 15-860-az0-ipos150h capacitors or to light weight they heat up and burn out replace with heavier capacitors if you dont know how to do it take to tv repair fixed mine very cheap works great now unplug tv take off middle black center section after u unscrew it push black panel downward take off only three screws remove metal panel the board that has the defective capacitors is the top one that your power supply cord plugs in to remove board dont touch electronics of the board because of static electricity in your body take board to have capacitors replaced or pick up some at radio shack and replace them yourself soldering iron is required to do the work yourself

I have 3 Polaroid TLA-01511C 15 in. LCD Televisions that have no picture but does have sound. Is this a common problem with this model?


I replaced three capacitors on my power supply board and the unit started working again, There was two 680uf 10v caps and one 1500uf 10v cap bad.

Samsung 50" plasma tv with no picture but has sound.


I just had a similar issue with my 46" Samsung LCD and fixed it myself for $5.11! I realize we have different tvs, but I bet it is the same issue ... crapped out capacitors.

I researched the problem online and most places, like samsung's site, referred me to call a repairman and called for the whole control panel or power supply to be replaced for anywhere between $400-$1000. I was like ... "screw that" ... I refuse to put in a fautly part in the place of a faulty part. So I continued to research.

That's when I stumbled on youtube. There are many how to videos on how to tackle this daunting task. I read that the issue was more than likely faulty capacitors and there is a very easy way to tell if it is in fact the capacitors that are blown. instead of having a flat top, faulty capacitors are crowned or even ruptured! When I opened up my TV I saw 3 blown capacitors!

So I bought 3 new capacitors all with the same uf and higher volts ... I think all three of my capacitors were 1000 uf and 25 volts. I kept the uf the same (recommended) and raised the voltage to 35 volts. It doesn't mean more volts, it just means it COULD handle more volts if it had to (which was the problem those cheap Samsung bastards screwed up on). This is a very common problem with Samsung TVs.

Anyway, I have never soldered before, but I did it. I warmed up the solder on the bad capacitors and removed them them slid thenew ones in and soldered them in and popped everything back together ... and PRESTO .... the damn thing works better than ever!

3 capacitors= $5.11
1 solder gun and solder= about $18
fixing an incredibly intimidating TV by yourself= PRICELESS!


Seriously ... don't be afraid to F up ... check it out on youtube and other place and save yourself a bundle. Source(s): I just fixed my TV!!!!!!!!

What capacitor should I use to replace it?


470uf 35v -located on the power main board this capacitor is slightly larger in diamiter than a pencil and about 3/4 of an inch long. there are three of these next to each other. the center one is usualy the bad one but for two bucks each your better off replacing all three.
