Sony KDL46V2000 TV. Screen comes on and goes off in continuous cycle

Hi, I have a Sony KDL46V2000 TV. If I switch it on the screen lights up normally but within a second or two the tv screen shuts down and goes black. The green standby light stays on and blinks once. The screen comes on again and then goes off. The green standby light stays on and blinks once and so on with this continuing cycle.

SOURCE: Blank Screen

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

SOURCE: TV shuts off within 5 seconds of turning on

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

TV powers on and goes black.

first i'd say try all the normal things...

swap sources, check to see if the osd comes up, etcetera. it might just be that the tv isnt receiving a signal from the source its tuned to. see if theres a way to factory reset the tv, try it.

if no matter what you do nothing shows up...

maybe the backlight burned out or maybe something on the mb burned out. go over and sniff the tv, notice any smell? if this is the case, i dont suggest trying to fix it new screen.

Hi There!

Sony TVs are very difficult to assess at first, so one would first need to know how a TV works and then the experience that goes with it. Every model is different and has different faults that make them NOT work. I would recommend to have it repaired by a technician. I dont think this is something you can do with a remote or on the unit. It is internal. Good Luck, JUS004
