Question about Sony KV-32V35 TV

1 Answer

No power. I have a 1997 Sony KV-32V35 tv. Tv turned itself off while we were watching it. Now it won't turn on at all. Do I really have to spend $300 on a power supply?

Re: No power.

Usually, in those Sony sets, a crack developes on a small transformer in the horizontal drive circuit, which causes the horizontal output transistor to short. This immediately shorts out the switching transistors in the power supply and blows the Sony 0.1 ohm resistor fuse. A shorted flyback (high voltage) transformer will also have the same result. The power supply does NOT need to be replaced. The parts should be replaced, the flyback checked and the board resoldered by a qualified tech familiar with Sony sets.

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Sony KV-32V26 turned off while watching, now I can't turn it on

I have a set I'm working on right now, same model number and symptoms. It is a fairly common problem and the repair consists of replacing 3 transistors, one resistor and one VDR (voltage dependent resistor), along with re-soldering some connections on the main PC board. You'll need a technician to do the work, and it will likely be well over $100 to repair. I would consider replacing the set with a HDTV model if you can afford to. The picture tube may be the next to go.

Sony kv 36xbr400 - Won't stay on

Problem is in the secondary power supply which provides power to high-voltage and scanning sections of main board. This is called BOARD D, and has the high-voltage section, flyback transformer, and control IC on it.

Can't be fixed by user, needs service tech and new part, around $300

Could be a problem in the shutdown circuit,in the HI Voltage detection circuit,or the flyback transformer. If your not a tech, you shouldnt be experimenting by adding parts as its going to knock you against the wall if it bites you. You should start out with a service manual and check the voiltages as now thinking it could be the power supply voltage regulator also. Please call a pro to assist you with this repair. Good Luck
