Question about Olevia LT37HVS 37 in. LCD HDTV

Speakers not producing any sound

I hit the power switch and then cut it back on the TV was on when I did this.  When the power was back on the TV made a loud electrical sound and the screen was fuzzy.  I immediately cut the television off and then back on and the picture was fine, but the speakers made no sound at all.  The mute is not on...we tried adding additional speakers but they will not work either.

Re: "When the power was back on the TV made a loud electrical sound and the screen was fuzzy."

That means that the power source had caused an internal damage.
If you heard noise, then it is either a blown component on the sound board, or a blown capacitor on the input board.

The TV must be taken apart and inspected by a technician to fix this.

Had a similiar problem on our Sam, I would have bet it was a speaker issue.The service man said it was a vibration problem caused by the plastic cabinet. He tighten the screws and it was perfect for about 6 months. It's time to call him again...

Hi and welcome to FixYa,

Offhand, your description indicates a probable fault in the audio amplifier section, most likely the audio output IC. This of course would require opening the unit, familiarity with electronic circuitry & components, use of a DVM/VOM and a soldering iron. It would be to your advantage access to a service manual or at the very least a schematic diagram. Should you be uncomfortable performing a DIY (do-it-yourself) perhaps your best bet then would be to seek the service of a qualified professional.

If you are considering a DIY, pls post back, confirm that your unit is a Olevia LT37HVS, availability of the DVM/VOM and a soldering iron.

Good luck and thank you for using FixYa.

Poor sound quality


A new LCD TV has expansion sound capabilities requiring adjustment to acheive viewer experience. First, the TVs default sound is what is heard soon as the powered on. Tempering with the remote controls volume fucntionalities to achieve adjustment suitable. The volume feature on the remote produces adjustment either reduceable or increasing sound magniftude. Hower, the LCD TV is capable of producing extensive qualility sound with separate devices that generate sound. For example, acquring an external speaker system mentionable as home theatre system has already build blusting capabilities requirements. Once an external home theater sould producer devices are connected to the LCD TV, the expansion capability is increased. For example, the home theatre devices have woofers as bass magnifiers, tweeters as sound impression magnififers, and additionally, speakers with magnifier capacities. The LCD TV is designed to accomodate any extenal devices only mentionable example as the home theater sound sytems acquirable at retail. LCD TV sound capacities are capable of being modulated by using the remote control to access the settings areas on which sound is alteratered. Consult the LCD TV user guide for additional details on manipulating audio sound functionalities.

Sound keeps cutting off


Let verify first to narrow down to where the problem can be, attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits are over heating, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

I have a panosonic plasma tv when i switch it on it tell me there is a speaker short and then switches it self of model number pdp507xda help


It's the internal circuitry problem. Try muting it and put audio connection to other speakers if it repeats, your TV audio system is internally dying.the audio connections has to be checked and faulty components should be replaced.
1. Speaker short.
Open it up and check the speaker connections. ONLY if you have basic skills working on electronics and don't have a warranty.
2. Sound Volume "Leveler"
Look in your sound option menu for a sound "balancer" option and turn it off.
If this doesn't work disable the sound and invest in that surround sound system (external speakers solution of your choice)

-----------
try this.for first unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the audio circuit board are getting short in between so the circuit is not getting completed and cutting in between so the tv starts and turns off. if the tv is connected to externalk speakers then check out without connecting the external speakers and see whether it works.if it works that means tv is perfect.but if tv is having inbuilt speakers that its confirm problem with inter audio circuit of tv.so try connecting external speakers at the back of tv and check out.

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.
