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.

TV has vertical folding of picture and loss of vertical hold.


Hello
The vertical output section of your Jensen TV is faulty. Usually this section has an IC circuit. Check the solder terminals of that IC for loose contact. This IC sill heatup while working. Repeated heaning and cooling will make ths solder terminals to get loose. It is very difficult to detect the loose soldering; as thay may be microscopic in size. Just resolder most of the suspected solder terminals by applying a little more solder, without making any solder bridge in between them. This must solve your TVs problem. Check the electrolytic filter capacitors also. Replace them. It won't cost more. OK.

My Hannspree TV volume goes out intermittently. Any way to fix this?


there's no faulty parts on your unit but sure that you have a dry joints on the sound amplifier section.

Look for a qualified technician to re-solder for a dry joint on the said section and it will fix the problem.

If you have knowledge in soldering then open the back panel of your tv.
Then observe first because you have to pull-out some connector from the main board.
Remember that anything you pull-out will be back to their position as you finished resoldering.

Try to trace the connectors of your speaker to the main board.
It is connected to ic which have a heat sink.That's the sound amplifier ic.
Find the cold solder around there then resolder it.
You can try the tv, if you hit the cold solder then intermittent sound will be cured.
Remember that before you try turning on the unit be sure that you returned the connectors to its original position. gud luck buddy...

Thanks for using fixya...

I need TDA9380PS/N2/2IO968, model tv21bl101mother board how i can get it and also required address of banglore service center


Hello
TDA 9380PS/N2 is now very difficult to get. It is a philips product. Tehre are many types of motherboards, which you can buy fro open market in Banglore, which will cost around RS750/= or so, here in Kerala I gets it for RS850/= and I've replaced so many of them. All are come with all fittings materials including remote hanset, 255channels, and seems good. Most of them are Single-Chip based kits. You can buy it from Banglore more cheaper than here in Trivandurm, Kerala.
Eventhough you can get the above numberd Ic, it will cost aroud Rs850/= or so, and is worthless now. Think well and do.

Hello, I have a student in our electronics class that has an Emerson EWF2702. Problem is the tv has sound but only a white line will show up on the screen when it's turned on. Can you provide a diagram...


Hello
A single white line across the screen denotes the absence of vertical sweep. Its vertical output section, or its vertical deflection coil section [integrated to deflection coin assembly fixed at the neck of picture tube] may got damaged. Deflection coil faults are very rare. You just look into vertical sweep output and its dirve section. Check for all voltages. Check its main supply voltage. The output voltage must be almost about the half of its supply voltage. Usually most of the modern telivisions uses an IC in this stage. Sometimes that Ic may be faulty. Check it also. Schematic diagram of Emerson is not available with us; and is ver difficult to get. If you wants any further assistance contact me. gopakumarg43@ymail.com.

No picture just get a white screen. Can it be reset somehow?


Hello
You haven't mentioned, whether there is sound is Ok or not. Anyway, according to your description I understand that there is no sound too. Assuming this I advice you to replace its tuner. If there is only a white screen, that is a raster only with no grains, tuner or chroma Ic may in trouble. In your case it may be chroma Ic itself. If chroma ic fails there will be no grains. In most of the modern TVs One Chip Micom is used. That 90% of tha sections are integrated to one Ic. Video If, Chroma, vertical and Horizontal Oscilator, sync: circuits, System Control etc. If any of these section inside the said ic fails, replacement of that Ic is the only remedy. You just check the chroma Ic first. If it is fauty, it will heat up more, such that we can't touch it. It will be heated upto 50 to 65 degreeC during operation. But not more. To check this, open the back cover of the Tv, locate the said Ic [it will be larger in size normaly have more than 50pins of connections on both sides; say it as DIL type, means Dual In Line], switch on the tv; without touching its any internal parts, wait for two or three minutes, switch off the set and plug out the mains chord from wall socket; and just touch it with your bare fingers and feel the heat effect. If it is too hot that you can't touch it; it is the faulty. Be caucious during this process. Never touch it with power supply is energised. Keep the power plug out from the socket, before doing anything inside the Tv and keep the children away from you.
