No power, but still i can control in remote the power switch, i heard the relay "click" but still i can't obtain the power. i measure the capacitor and it work normally, i try to measure the 120v going to mainboard but it suddenly decrease the voltage to zero.

Re: power supply of tv

If voltage drops means there is a short circuit in your tv. 1 disconnecting 120v line if supply becomes ok then there is short ckt in horz.section &if it does not gives 120 volts then there is problem in power supply. please check as per instruction &let me know. good luck.

I have a SONY TRINITRON TV Model no. KV-XR29M80. Unfortunately, the Remote Control supplied with the original TV set is not working. How can I obtain a replacement Remote Control for the set ? I live in...

The original remote control of your TV is available at Ebay. It is priced $8.99. Just order them with the exact model number of your TV and order for a remote control of the set. They will get it at your doorstep. OK.

TV will not turn on

Hi, If the clicking noise is metallic, could be a relay switching on/off. What's curious is that once powered on by remote, apparently the clicking doesn't affect the TV, meaning it continuously work. The relay is suppose to turn on or off a function of the TV and apparently it is trying to but there is not such effect since the TV, as I understand from your post, works. The relay can be for the degaussing coil, power supply, over voltage protection. Since this involve a little diagnosis of the electronics, soldering and probably a minor component replacement, an on-site service/repair man would be your best bet. Even if it were a nuisance/minor repair, you can at least get the clicking noise out. Other than you get to get a checkup of the TV and diagnosis of what caused/started the clicking sound in the first place. Hope this be of help/idea. Post back how things are or should you need further information. Good luck and kind regards.

you need to check the voltage output of your power supply section.This power supply supply is a switching type power supply.there is a chopper transformer in there.its supply is a dc voltage unlike any other transformer which is AC supplied on the primary..First step.
1.Using a multitester measure the primary supply it is a DC voltage around 220v - 110 VDC
2.Measure the secondary output.The out put is AC voltage the supply for the B+ going to plyback is 115vdc the second output is 12v run through a regulator and the regulator lower the voltage to 5vdc.this 5vdc supplies the system IC and the jungle IC.this ic process the switching of the plyback transformer and the plyback transformers output supplies the voltage of the whole system including your relay in the degaussing section....once the plyback is activated the tv will now turn on...

good luck!Hope i helped you..

please rate my help..god bless!

Sony tv wont turn on, standby light just flashes

check for an open resistor on the power supply, it is actually a fusible resistor, (white) if open, then check the converter, some sets have two separate and some have it as one. it will be on a heat sink on the power supply. if shorted then check for a shorted horizontal output transistor and repair cold solder joints on the horizintal drive transformer which is the real cause of this problem

Won't turn on - relay clicks, power supply squeals, relay clicks, etc,

need check B+, standby power supply, and Horizontal defletion and components

Toshiba cf32c50 tv will not turn on

This is a typical condition if the power supply has failed or a power-consuming circuit the supply services has exceeded a predetermined current draw. The relay you hear is preventing further damage or even fire.
You will need local tech help with this.

isolate power from hor.output section. if voltage becomes normal 130v &it does not drop then power supply is ok. now check hor output for leaky compnents near eht specially capacitor & diode. check hor output tr. at last eht. you can clean print near eht.

Stand-by LED blinks-no picture or sound

the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician
