TV would green light on for about 5 seconds then click off. I replaced both an IP@ Board first with no change then replaced with an BM3 Main Board also, with no change. What next ??? Thanks, Pat


its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Tried holding dwn the button on ps3 till the beep but still cannot get it through hdmi on tv


You need to try the AV cables.

It is common that the HDMI output goes out. It is an indicator that your motherboard is going bad. Eventually it will. These are just facts not meant to scare you. Just keep your receipt handy.

If you cannot get the menu on AV, then you have what is considered the 'Green light of Death'. It's not my term, but if you search this term, you will find people with similar issues.

You will need service, even we cannot fix every Green light of Death consoles. They have to be sent to SONY for a replacement, refurbished, or paid unit.

Good luck

My TV will not turn on. the green led light comes on and then swiches over to the red standby light and flashes 13 times. Does anyone know what the problem could be? I have a sony TV Mod no. kdl52w3000


Sonys are known for this. The tv may be going into shut down because a circuit such as the power supply cirucuit or high voltage may need repair. Call a service man, you probably only need a portion of the circuit repaired not the whole board!

The screen was damamged on our lcd sony 40" Tv can it be repair;


Sorry, the screen can't be repaired. Only screen replacement at that point. The screen itself costs $350 minimal if you can find one for a good deal. And we're not talking about the labor costs involved.
At this point, it would be cheaper to buy a new TV.
Sorry to give you the down side of the TV screen.

MY SONY BRAVIA 32" CRACKED LCD


Unfortunately in most cases the cost to repair the tv is not worth it. The replacement panel plus the labor in most cases cost's more than what the tv cost you to buy. You can call Sony if you are intrested in the cost of the panel. 1-800-222-7669

36 inch sony wega trinitron


I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.

Blinking what - how many times before it pauses and then blinks the next set?? Sonys have an error code of blinking to help isolate the problem... (count the number of times it blinks before pausing and let me know).
