SOURCE: Onida crt tv picture ok but no sound .supply also ok I replace sound ic tda2616 I checked both speakers

Have you checked the supply voltage and other pin voltages to this IC? Check it. If all are found OK, and still you do not get sound, main IC is likely to be faulty. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

How can fix a 33v tuner in the place of 5v tuner

33V is used as the tuning voltage, which has supplied to the varactor diodes inside the TV, and not is the supply voltage. The supply voltage is 5V itself, and this is a 5V tuner. The only thing to note is, whether it uses SDA - SCL or Bl -BH. This is the type.

When I turned on my TV,I saw channel 1 and then everything turned to snow. It will not even turn of by remote.

Hi

Your tv tuner or associated circuit has somethig wrong. It may be the 33V zener diode in he tuner supply line or the tuner itselt. This task require a qualified technician or a keen electronics hobbist.

I have Universum FT 81804 tv with 11AK19 chassis that wont save channels. I replaced IC Memory chip and it still wont save any channels.

Check whether there is AGC voltage change at the AGC terminal of the tuner, when a channel is tuned. It should change as soon as a channel is tuned. If there is no change in this voltage, make sure that the tuner is faulty.
