Question about Sony KV-32S66 32" TV

Open Question

No picture, no sound and flashing red led

This set was running fine and just turned off. When powered back on the Stby timer LED flashes and power relay clicks on but that's it. Found Horiz output Q502 (2sc5148), MX0841 (IC601), (R607) .47 ohm fusible, and D648 B+ zener (EZ0150AV1) bad and replaced. All replaced and even swapped out Flyback without any luck. Suggestions would be appreciated. I really don't want to replace the 'A' board but...

Sound, no picture, Red LED 4 flashes


Hello Thanshar, Hi, you TV has sound, but no picture. this could be several things, and let us add the red led flash. In my analysis, no picture means no high voltage is reaching the picture tube. this could be due to a bad Horizontal output transistor, and/or a bad flyback transformer. This bad transistor is causing an overload to the power supply section, causing the 4 led flash to blink. Now i want to know if you want to do this service or get professional help. if you decide to do this by yourself, this needs to be performed: the Horizontal output transistor must be checked for short, the horizontal flyback transformer needs to be tested, the deflection yoke also needs to be checked, especially to horizontal coil.

Sony Trinitron TV. No picture; red standby/timer light flashes.


My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

Toshiba 36HF71 has sound but no picture


Same problem with mine. Relays click, sound, no picture and a flashing power LED. I finally found a schematic online. I went through the high voltage circuits and found the power transistor 2SC5570 was shorted out. There is also a pico fuse in that area but my was not open. I replaced the transistor and prayed the flyback transformer was not shorted. It wasn't, I'm watching my old 36" right now. Not a bad fix (17.00) bucks. Wonder what a service tech would have charged ;)

When your set first turns on it runs a systems check to see if the boards inside are safe to apply voltage to. also it checks the power supply to see if it is safe to power up.
Either it needs a factory reset which the procedure changes for each model. or it simply has more wrong with it after the surge and requires more to fix it then the cost of a new set.
The best bet is to look on EBAY for a similar set with something like a broken screen. swap out your screen into its chassis. 
if you do not feel up to the challenge of doing that you may be looking at repair costs and parts that are more then a new set.

Picture wont turn on


Red LED flashes probably five times.
You have not mentioned the model no, so I have to guess it is few years old model.eg FE2 chssis or similar.
Most common reason, R618 270k ohms in power section has gone high.
Second, screen voltage control is slightly misaligned.
Third, high value resistors on tube base, normally two connected to screen voltage control pot have gone high.
You need to have some knowledge , a multi meter and soldering iron and know safety procedures before trying yourself.

No picture, however there is sound


Is this set hooked to cable? Is there a cable or satellite box? When you press the menu button, do you see the menu on screen? Do you see anything on the screen, such as snow, or is it completely black? If the signal is OK and the TV has no picture at all, the red LED on the front of the set should be flashing a certain number of times. If the LED is flashing, the computer has detected a problem in the set and shut the picture off. If this is the case, there is no way for you to bring the picture back by pressing buttons. The number of times the LED flashes is the computer's way of displaying exactly why there is no picture. The set should then be serviced by a qualified tech familiar with Sony TV's. If the LED is not flashing and the menu comes up on screen, check your signal source. If you are using a cable or satellite box, that box could be bad, and if you are using RCA jacks, the yellow (video) wire could be bad or pulled out.

Progressive power up problem


Yeppers. Sounds like the standby power supply has a bad capacitor in it and the regulator Ic is defective. These parts should only be replaced by quilified technician as there is very high voltage inside these sets. Good Luck
