With no stand by light, you are not getting power.Unplug TV and check fuse on power supply. You will need a meter to look for shorted components and possibly leaky/bulged capacitors that are killing your power supply. flickering could be part of the bad power supply or possibly a problem with YSustain area of your TV

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.4_3_2012_1_28_26_pm.jpg look at power board for caps puffed up like these

Television only has purple light and wont turn on.


Hi, the standby light indicates that only a portion of the power supply is working. The TV does not flicker or make any type of noise when the power key is pressed also could be a main board problem.

My matsui m32lw508 will not switch on just flickers then the standby light comes on.


Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care .......

I have a Gigaworks 750, the Audio Pod is not working, however, there is power going to the subwoofer though the power light is flickering. Hope you can help me in solving the problem. Thanks


I did fix this problem and the whole bunch of other ones with the s750 system.

"light is flickering" is a very common! It shows that there is a problem with STANDBY power supply:

1) Yellow glue became conductive (needs to be completely removed)
2) Capacitor malfunctioning C61 (68uF 450)

3) mine had TH1 cracked (replaced from PC power supply) and D9 diode.

If this successfully fixed, you will be able to get 2nd stage power supply on (Relay or power on button)

If you will have problems there, there is a whole bunch of test needs to be done (capacitors, IRF740 etc.)

My Sceptre LCD TV Power turns on briefly (blue


Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.
