    If your service manual is not available better take it to an authorized service station to check if it is repairable.

I have a 22 inch proscan television. i hadn't used it for about six months prior to now. The picture is perfectly fine, but the audio will not work at all. I have tried unplugging it and letting it sit...


It sounds that the audio output section circuit to your TV has the fault. The audio output IC, or speakers should be suspected. Contact any service technician. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

Proscan flat screen went black and no sound


The power supply regulator section of your tV has the fault. The set need service. Contact any experienced service technician, as it will be dangerous for an unexpereinced person to work with the power supply regulator circuits.

I have NO sound!


Check for two locations - on the back of the set itself, lower right hand side. A switch for the speakers (EXT -up-, INT -down-) should be in the down INT position for the TV's internal speakers. Also on the TV screen go to MENU> AUDIO> SPEAKERS> press enter to check the ON button. Of course the other option is a separate amp (using the rear Audio Output RCA jacks), or below that the LEFT/RIGHT external speaker connectors.

Does not power on. Q951 charred


you can look for the model and brand, look for it on the internet and see if you can have the schematic diagram, you're lucky if u can. Lightning will strike first the tuner side, if there is a red blink, the primary side may be okay in switching type regulator, just replacing the charred part may not solve the problem. look for shorted components on the secondary of the power section.

No picture or sound


You probably have one or two diodes bad which would have to be unsoldered to replace. Since it is a small TV, it may not be worthwhile to take it to a repair shop -- if you can find a good electronics tech with soldering equipment and a multimeter, have them check out D951 a 12 volt zener diode near the power relay. If good, then I would check out D941 and D942 in the power supply. If all three diodes are bad, the set probably took a power surge or lightening strike and could have other shorted components as well.
