Question about Televison & Video

Open Question

Model # L46WD22YX5, 46 inch RCA. Sound went out. Unplugged TV for 1hour. No help! This TV is 2 1/2 months out of warranty. HA!! Go figure! Recently change antenna and all wires. We do not have cable. When setting up TV, picture is beautiful but no sound at all on any channel. I would love to be able to fix this on my own, but this may not be possible. Hope you can help! Thanks.

Hello cote,

This indicates a problem in the power supply either the low voltage switching supply or the High voltage power supply. The sounds you hear is the shutdown circuit activating, I would not suggest that you try to repair this problem because of the dangers involved. I would suggest that you take it to a qualified TV repair shop. This problem should not cost you much, however it is the best choice for the problem you described.

I hope this helps,
Thank you,

I recently had the same issue with a 6 month old Panasonic...the Tech determined that a component on the main circuit board failed. I was lucky and it was fixed under warranty. Good luck!

Tv popped and picture went out


im srry to tell you that you picture tube blew in you tv this can happen from many things as simple as a defective one .. to a bad power surge in your house ... if it is under warranty they will fix free of charge .. if not you'll have to get a new tv .. a new tv in most cases is cheaper then tryin to just by the tube .. oh and if its not under warranty .. you could always just say it surged and claim it on you home owners insurance =]

RCA 57 inch hdtv Model#HD56W58 has sound but no picture.


WOW...had a high pitch noise, came and went...got worse as time wore on. Would shut off the set, times it cleared times it didn't. Warranty folks set out a TV repairman--said he had worked for RCA exclusively for years...anyway, explained that the 1k hertz noise was a known issue with the HD56W58 and that RCA’s published fix was "nail polish" applied on some board, had something to due with power and vibration...long story "presto" noise gone...but after 6 or so months we began to hear it again—say it ain’t so, but yes the high pitch was back. Same repairman, this time bigger problem...along with noise, the network card is broke and Fry’s Electronics (Irving, TX—hear that Corporate HQ at San Jose…your Irving store needs to be leased in and tote the company line...where's the customer satisfaction???) is balking at a “equal” replacement, they see it as take the less than equal product or get store credit…good luck & wish me luck with the equal replacement they tout when pushing the warranty.

No picture with VIDEO INPUT, only AUDIO INPUT works


Hi ,disconnect the cable and leave the three RCA cables in.Switch off TV and DVD player ,then switch on tv and dvd player next .If you see the dvd picture and have sound then i think the cable box is overriding the rca channel.I normaly use a scart connection for the dvd to cable box then another scart from cable to tv.Hope this helps..

Rca truflat with green tinted picture?


Just because a machine has failed, there is no cause for you to call it a stupid TV. And as it is only 6 months old, why not take it to the Company service Centre? There must be warranty.

RCA 27 inch TruFlat TV/ Walmart Feature Item "Defective!"


I AM SORRY ABOUT YOUR PROBLEMS WITH YOUR TV... AS IT IS YOU BOUGHT YOURS AT APPROXIMATELY THE SAME TIME THAT I BOUGHT MINE. I STARTED HAVING PROBLEMS WITH THE SAME THING YOU DID ABOUT 6 MONTHS AFTER I PURCHASED IT. BUT THEN I THOUGHT IT WAS DUE TO SOMETHING MY NIECES HAD DONE TO THE TV. MY DAD TRIED TO FIX IT AND IT WORKED FOR A WHILE AND THEN ON CHRISTMAS EVE 2006 IT WENT COMPLETELY BISERK!!! NOW I DONT EVEN KNOW WHERE TO GET THE CONTROL PANEL.
