SOURCE: I have a 4 month old sony bravia 1080 120mhz Sony

Not common but electronics are electronics , we can have failures right out of the box. Generally Sony is reliable and I must say that you should not have to worry about cost , Is it not under warranty - its only 4 months old !!

SOURCE: Sony Bravia V series is on standby. Does not turn on.

That is true. You need to change a new board as when the chip is blown, all the related SMT cap, resistors, and transistor were gone, too. Those tiny component are hard to repalce one by one. Importantly, some of them was changed value and it only happens when the TV is warm up.

TV will not power on at all. Is there a fuse or circuit breaker readily available.Sony KDL 46W4100 7yrs old Flat Panel LCD


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at 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.

1year 2months old Sony Bravia KDL46HX820 powers on for few seconds ; I see black clouds on the top left corner ; TV switches off and 4 red lights blink ; Please advice on what might be the issue


No Vertical Sync is the fault. This is a main board fault. The main board might need replacement. But before confirming, check all the voltages comes to the main board from the power regulator board. If you wish to know more about the voltages and their sources, check this link.

Hello George, hi it seem your TV is on standby mode, this happens when the power supply board detects a short, overload or any part on both main and power supply board gone bad. This needs to be checked properly by a highly skilled tech people. The problem could be the main board or the power supply board. we usually check first the main board, for any bad parts, like loose screws/wiring, bulging capacitors, overheating ICs, or water marks. If a OK, we then check the power supply board, well usually this is the culprit, bulging capacitors, or overheating regulator. or you could replace the entire power supply board. check for its availability online or on your dealer, ask also for service if the charge is reasonable.
