Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

I hope that you can use the warrantee.

Otherwize, it must be possible to repair it with a fried comfortable with electronic because the problem is not permanent. This kind of problem is usually an old capacitor or a bad connection (soldering).
It would be important to check if changing the ambiant temperature fixes the problem. (I.E. move it to the seller for 2h and try..)

Regards,

you must check ic 7101.7201,7301 they are the possible problem

Symptom shows its time to replace Lamp.
How old is this TV?

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!
