Power light blinks three times then nothing

A green LED that blinks On and Off is an indication on some models that the TV is receiving commands from a remote. By modelling, it just check SYN, SYN-ACK signal between transmitter and receiver. No worries.

How to tune universal remote rm-300f+ to my tv

How to do an auto search for a Livewire Rm-300f+ Universal Tv Remote. These cheap (£1.00) remotes are available from poundland, etc.

1) Turn on your TV, ensure it it tuned to a channel and the sound is on.
2) Press the [set] button for about 5 seconds, until the LED stays on.
3) Press the MUTE button, the LED should flash twice.
4) Point towards the TV and press the power button. Don't worry if nothing happens.
5) Press and release the power button every second or so, eventually (for me about 120 times) the sound will go off. NOW press the [set] button to confirm your setting.
6) Pressing the power button again should switch the TV off. If not you're going to need to go through it all again.

I have a Sony Wega KV-34HS420 TV that takes several tries to turn on. When I push the power button or remote power on I hear the normal click and the sound comes on for 3-5 seconds but then I hear a second...

Since the set appears to "recover", it suggests either a poor solder connection or bad cap somewhere in the power supply. The 7 blinks indicate the problem circuit is in the horizontal area. Check the regulator (STRxxxx) IC in the power supply. If you do not have experience working with TVs, please refer this repair to a shop. The regulator IC costs around $25.

Blank screen on startup on Sony KV-32FX20U

All Sony sets will stay blank until the circuit is ready to power the tube. If there is a problem detected inside the set, the tube will remain vlack and the standby light will blink. This blinking will repeat a count as follows: Blink count, pause for a second or two, repeat the blink count, etc. Some Sony sets will play for a while then flash off and on. This is usually an indication that the picture tube is starting to fail. In your case, you should see a blink code. If you can update this with the blink count, I can use that info plus the model number listed above to provide a possible cause and the parts required to repair the set.

No sound or picture now

The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

TV solution

You may have a bad solder joint on the horizontal driver transformer or somewhere else in the set. I found this problem with this transformer several times. Stargazer
