Re: sony tv, no pic or sound, lcd blinks

Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sony KDL-46XBR4 - no picture or sound (black screen), the standby led blinks 5 times. I need to wait for 1-2 hours before the TV turns back on normally. If it is on (working normally ) and I turn it of and...

I am certified SONY Technician and I can help you for free.
Self-diagnostic function in your TV indicated that you have problem with T-CON board. This is video processing board attached to the panel and acting as video adapter between Main board and LCD panel itself. As long as I remember T-CON is considered to be a part of LCD Panel by SONY and have to be covered by manufacturer warranty for 2 years from date of purchase.
So - please locate your receipt form the store - they WILL ask for it.
Have a good day!

Sony KDF-E42A10 rear projection TV. Won't turn on.

Start by changing the lamp. If you got 5 years out of the old one, count your blessings, most folks only get three. The lamp is designed to be replaced by the consumer. Ebay will carry a replacement for you or you can get it directly from They've got good prices. The lamp door is on the back. Its really easy, give it a shot.

My Sony Bravia turns itself off Stand by red light blinks twice.

If you bought it brand new from a dealer, I would take it back or have them come out and look at it. Less than a month old, it is still under the 1 year MFG warranty or the very best a 30 day one.

Screen became dim over time and then blank. Red LED lights blinks when on and sound is fine. Is this the bulb, unlike the others that went suddenly?

There is more than one flourescent tube in your TV, It could be possible that one after the other has failed, these should usually last a few years depending on usage.

If it is not the tubes then there may be a fault in the backlight inverter although this would more likely show up as a sudden failure.

How old is your TV?
