PRoblem is in the start-up circuit for the high voltage power side of the power supply. The 5 volt, stand-by circuit, is obviously fine. Need to take voltage measurements on start-up to 32kv side of transformer to diagnose. Possible flyback transformer or voltage regulator.

Proscan LED TV Will power up the red standby light & standby on amber when turned on but does not show picture or sound unless I unplug and replug over


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

TV goes to blank screen standby after one second of normal functioning green power light on. When in standby state, the TV is blank like it's off and the red standby light blinks FOUR times.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

When turning on the TV all I get is a click sound, the red light remains red and no picture or sound.


Sounds like the tv is on standby, and needs to be switched on after via the remote control.

37PF9731D/10 - when turned on the tv power light remains green but no picture or sound. Just a clicking sound - like it does normally when swiching on from being on standbay. It reapts the attempt to turn...


The clicking sound is from the main power supply relay being turning on and off, it is driven by hte main board and it gets the power from the standby power supply board.
You need to check the main powwer supply board and the standby power supply board voltages.
Check the resistor in the main power supply board also

My Sony KDF-50WE655 does not turn on. Only the standby LED Flashes several times and then goes steady green, but the lamp light remains off.


Hello
You just count the number of blinks of the standby light before it goes out to green. In sony sets this blinking count ic critical for us to locate the faulty stage. You just count it after switch it Off by Power switch and Switch it On by the power switch at the front of the TV, for at least three or four times, and make sure abut the number of blinks, and report it to me. Ok

Hi, I have an LG Flatron TV which I bought 6 years ago. Good picture, no problems until now. I put the set on standby via the remote. Later, when I put it on via the remote all I got was sound and no...


Since the screen keeps turning off and sound only remains have a look at the inverter board for any buldging capacitors which look like blue cans, there is most probably a short in the inverter and the powersupply is sensing this thus turning it back into standby to prevent damage to the tv.
