Sharp 20v-w70m speaker and IC ok but no sound


Check the input voltage to IC. If it is absent, the IC won't work. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts.

No picture. Sound is OK on Philips DPTV345 model 51PW9303/17F


I would check the solder on the Vertical output IC as ofetn the soolder will crack and the CRts will shut down to prevent damageing the CRts when vertical drops out. If the solder looks good I would try replaceing the vertical IC very inexpensive and you can get the vertical IC from www.tvrepairworld.com

No sound picture ok adio output ic good sharp tv model 21V-FW150M


If this is confirmed the fault seems to be in the preamp section or the SIF- sound intermediate frequency section. If you have confirmed that the output is workingg by conneccting an input to the audio input then it should be confirmed that there is no output from the audio line out.
If so you will need to trace using a AF- audio frequency- signal to confirm the area of loss of the AF.
Sometimes this can be some coupling stages or an OP-Amp.
Please trace using a signal and a voltage test. If not get help.

No sound


Hello
You haven't mentioned about the picture at all. Assuming that, picture is ok I suggests. Ok
If the picture is Ok and there is no sound output from the speaker, your TV has either speaker problem or output Ic problem. To assure where is the fault, you just place your ear very near to the TVs speaker side, and switch on the TV. If you hear a "thumb" sound or a "HUM" sound, your TVs output ic has blown out. If you did not hear any sound at all, the speaker of your TV has gone.
If you have a little knowledge in electronics, you can do it by yoursef. This is a minor mistake. Opwen the back cover of your TV, locate and note the type and number of the audio output Ic, go for that and get it replaced; if the fault is related to Ic. You can do the speaker replacement also by this way. I have given this much advice, assuming that picture in your TV is Ok. Otherwise the fault may be different.
