Question about Televison & Video

1 Answer

We have a 20MF 251W Series LCD TV. After the set is on for approx. 20-30 minutes the sound goes off ???? After approx. 5 minutes it comes back on. Can we correct this problem? Please don't ask me to enter credit card information. I do-not want to pay for advice that you should give to your customers for free! Thanks

    What a shame, this was a replacement for the original we had problems with. We received the replacement in 2008. I don't think we will buy this brand again. Thank you for your help.

Well first let me ask this, how are you a customer if everything is free? You are a customer of the TV manufacturer... and the store you bought it from.

Anyhow, it sounds like the sound board for the tv is going bad, also known as the S/T Con Board.... It is going to need to be replaced, I am sure the problem will continue to get worse otherwise. If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

Thanks
Tim

Just do a hard reset to this set and check. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. This must make it a hard reset.

that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..
