Power board short and bad capacitor blown, capacitors usually pop because of shorted or open rectifiers and linear devices that warp inside. This happens due to excessive heat exposure from the current draw. Bad diodes and FET's are usually the root cause as to why capacitors bulge then eventually pop. This means the the x-y sustain boards are not getting their supply voltage resulting a no picture....

The red light flashes an error code for a technician to read, the tv is in protection mode to prevent further damage. Get it serviced at your local repair center or take it back if its under warranty.....

There are two types of reset to TVs. The first is simple to do; a Hard Reset; and the other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Hi, akk you have to do is search online with a search engine such as googleor bing. Simply enter make and model of tv and power control card, or power regulator card and several results should be thrown up. If you include your city / province / county / state the nearest suppliers can be found
It is a very straight forward process.
Be cautious with your card details if buying online or over the phone

There should be a short circuited printed circuit board inside the TV, which causes short circuit shut down. Contact any service technician. This is not a user repairable fault. Try these codes. If you wish to get more, try the following links. Both the sites linked have set-up code list & set-up procedure to many popular brand remote controls. Surf the sites with patience.
