Accroding to your model number:(KV-...) In sony tv units power supply porblems is very low unless a power surge.
You have to check these things.
1. Stand by 5V available or not
2.If stand by 5V available press power and check B+ is getting or not
3.If B+ available check Horzontal oscillation
4.May be H-out transistor or video amplifier is bad.

Sony kdl55hx800 red light blinking 2 times

Expert: Shahid replied 2 years ago.
OK, 2 times red blinking light shows problem with main power supply board that isn't working and need to be replaced in TV.
Power supply board has two type or supply, one is called standby power and other is main power, main power supply isn't working for some reason like defective regulator chip etc so TV shows that red blinking error code.
Power supply board replacement would resolve the problem.

Sony crt tv (KV-BZ14M70) led blinking four times in stand by mode, so it means?

Hi Ullah,

LED blinks four times on KV series means that the Vertical deflection circuitry encountered a problem. You can repair it yourself if you have knowledge in electronics, knowledgeable in soldering and desoldering of parts on the board.

SONY KP-61V90 tv will not power on, red light in front,

Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.

Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10
Let me know for further query, if any.

No picture

I disagree with given info, this tv has no horizontal output transistor because it is dlp tv.
3 red light blink means lamp cover is not placed back properly after lamp replacement/ lamp checking. Make sure lamp cover is fixed back in its place securely and tight.

ALL the next is with the tv unplugged (NO NO power)
  • resold the jungle (video processor) all around
  • following the horizontal drive pulse path and arriving to the horizontal area just after the horizontal transformer and in the base of the horizontal DRIVER there is a electrolytic capacitor (if this chassis uses this one,) Change it (maybe is dry)
  • solder all components i just told you in the last step. horizontal driver, transformer, etc
  • remember:
  • if a transistor is blowing with no reason (there is a reason: the collector receives 130 volts but cannot hold it forever, It has to be in some place. if the switching pulse doesn't arrive to it the transistor throws this 130 volts and burning itself. i hope it is help full.

I have a Philips TV Mach3Line 29 inch 29SX8771/75R that wont power up. No Picture, No sound, no power LED, just a high pitched chirp sound every second (not coming from speakers). Is it likely to be worth...

The chirping sound indicates the power supply is starting finding a problem and shutting down hence the cycling trip can be caused by any number of faults but I would first try the Line output transistor for a short collector to chassis if this is ok then Philips TV are prone to the small blue high voltage capacitors (2/3 Kv.102k/222k) becoming short usually indicated by being burnt or very discoloured.. If you are not technically minded its best left to a Tech.. Hope this helps.SUPER8

TV - worth fixing or pitch?

Horizontal output and regulator transistor often short out on this model causing a dead condition. Also the resistor right next to the regulators goes open as well. has a sony repair kit to fix the power supply. You just have to check the numbers on your Horizontal output transistor to make sure you get the right kit for your model.
