Strange shutting off - now it wont turn on... help?!?!

Thunderstorm over the coax or /and the power supply measure the power supply by a defect cannot be measured anymore over an analog hand adjustable power Variac transformer from 0 to 240 volt. because a protection can be given by a defect t-con board (as suggestion) but the variac its good to bypass/ overhaul the build-in safety protection circuit inside the power supply board then sometime if there else are broken or bad components hard to find they can be sometimes intentional burning out or become warmer by twist the variac power slowly up from of zero volt until the max necessary voltage T-con boards that can have a problem with smd components sometimes they can burning out the defects but its only to do if there is no equipment to measure repair or nothing was to find without a service manual or other optical defects , an short-circuit tuner also by thunderstorm sometimes only the little ceramic capacitors what hangs to earth (chassis) if the thunder energy was coming over the antenna coax cable. the power supply can stand in a safe protection mode. then a refurbished board somewhere can be necessary that will give a reset to release the protection mode in the power supply.. Thunderstorm can be strange and much different and i have had 2 times repairing when there was only 1 ceramic short-circuit ceramic capacitor to find thats was with one leg is( on cold-earth) on the chassis. as the one and only defect component. A time in a TV and 1 time in a radio , sometimes its realy strange but comes it over the power supply its hard to find because of more recurring complaints if partial repair in smd circuits. hard to do without necessary tools.

tried to disconnect all the sources that have been hooked up to the tv that might cause of shut off. if still the same issue suddenly shut down, at this time you will need to check if their is a shorted in the inverter board for back light or power supply failure.if under warranty you can ask for assistance at the supplier to check the unit.

to diagnosed where the cause came from, first place to be done disconnect the connector that supply to the inverter board for screen back light which may have shorted line that can cause of suddenly shut off. then tried to turn on the tv with out the ballast board, if the supply from the power supply get stable and the indicator stay with out blinking that was mean the ballast board could be bad. by the way you must replaced first bulged capacitor at the power supply board. hope this can helped good luck.

Unfortunately the audio output ic has shorted shutting down the unit, the only solution is to have the part replaced.

it could be the lamp but it might also be what is called the color wheel.. have you checked the lamp .,, have you removed and physically looked at the lamp. also does the light blink after shutdown.

if complete service manual will help,you can download it from my ftp sight request at [email protected] its has 133 pages and 15mb big.has alot of step by step info.

try holding in the menu and input buttons together on the front panel for about 8 seconds to see if the self diagnosis feature will blink a two digt code then let me know what happens

Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.

When the set is turned on, the computer senses that something is wrong and immediately shuts the set back off. The standby LED will then blink a code, a certain number of blinks, to indicate exactly why the set was shut down. It is possible that your audio output IC is shorted, as this would make a pop or strange noises in the speaker just before the set shuts down, which it does to protect your speakers from burning up. The set should be looked at by a qualified tech familiar with Sony TV's.

olevia sucks! don't buy one
