Repair of Sony 21'' flat screen television set

The set was purchased and used in Nigeria since 2003. The screen went blank yesterday, November 21, 2007 in the course of listening to a network news. The standby lamp was flashing repeatedly, 4 times in about every 3 seconds. Please help diagnose the problem and profer effective solution. I like Sony products and I cannot afford purchasing a new one. Thank you.

Screen Goes Blank

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Pop - bang noise then went dead after a period of time

You've blown a capacitor and probably the horizontal output circuity. It's time to get a new LCD monitor.

Connecting PC to television

Hi and welcome to FixYa,

Initially, try the lowest possible Screen Resolution in the PC's Display Properties. You could also try lowering the Screen refresh Rates. This is especially so if the PC connects to the TV using composite (yellow) video out or S-Video. In some video cards/settings, it may be necessary to enable twin/dual view in the display properties.

Good luck and Thank you for using FixYa. Happy New Year.

Sceptre LCD monitor blank screen, blinking power light

Something has failed or is failing in the monitor. It may be serviceable, but may not be cost effective to do so unless something has just come loose. I'm assuming you have no problems with the new monitor. Your time line is a little confusing.

Monitor made a popping sound and went blank. no computer or tv signal coming through.

Sounds like a Power Supply comcponent failure in the high voltage panel supply circuit.
Backlight power seems to be ok.

Can only suggest obtaining repair quotations vs. Replacement purchase?
