Tv will not power on

Cheaper to replace than fix, trust me on this.

dead power board

Indicator Lights:
1.Headset Status Headset Indicator Light
2.Powering on Steady blue, then intermittent flashes
(changes to standby mode)
3.Powering off Red appears and goes off
4.Standby Blue intermittent flashes
5.Charging battery Red solid light. Light indicator turns off when
battery is fully charged and headset is off.
6.Low battery Triple red flashes
7.Pairing mode Blue/red alternating flashes
8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

Hello

There is something confusing the system control of your TV and it should me resetted. To reset it, just switch OFF your TV with its front panel power control switch, and after that, unplug the TV from the wall socket. Wait for about 5 minutes or so, and the plug it and switch It ON. If this does not work for the first time, give some more time to reset, say about an hour or so, and try. OK.

Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.

If you replace the lamp, but get the same problem, check the inverter board.

If you're not sure where the inverter board is, then you may need to contact a pro for your safety.

Good luck and have a good evening!

The indications that the power supply is going is when you start noticing flickering and sound like shorts when you watch TV...
I do not know how to answwr this without looking at it but first I will check again and follow how far you are getting electric to the board

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.
