Tv keeps self restarting after about 30 - 45

needs a tech to reprogram the tv ez adjusts, the parameters have to be set to their factory values

With the set turned off:

RESETTING THE LAMP TIME
When replacing the lamp, use the following to reset the lamp time.
1. If the Self-Diagnostic screen is already displayed, proceed to step 4.
If not, Power off (Set to Standby mode).
2. Press DISPLAY Channel 5 Sound Volume -
POWER
3. To access the Lamp reset, press 5 until the TIME category displays.
4. Press 1 until the RSET item displays.

I would first always check the lamp to make sure that its not burnt out. On my 50 XBR1 the lamp door is on the right side of the tv. But here is the code for three blinks of the light,

3 times, Diagnosis: +B overvoltage (OVP). Possible causes: IC501 is faulty (G board), IC5002 is faulty (G board). Symptoms of the problem: TV has entered standby mode.

Hope this helps.

Hmmmm! i suspect the INVERTER that drives the lamp, or it could be the power supply check for swollen capacitors on the board inside, and last it coul be a overheating component (is it wors after it's on for a long time)

Good luck!

Lamp,if it was the Ballast Lamp will not come on because Ballast Board is what Powers Lamp.

It is you Optical Block/OB. sony is offering an exchange/deal for owners of 50 and 60" xbr1. I have contacted them and they are going to send me a new TV at an awesome price. This is do to the class action law suit. optical blocks are very expensive. The tv itself is not woth the investment.

yes, the door has to engage a switch and if it doesn't the tv will not come on it usually has a 3 blink error if this is the problem. Is your red light flashing in a 3 blink series?

Unplug Tv from AC for minimum 30 minutes, at right bottom side of TV there is cover. It is lamp cover, open it and pull out old lamp and put new lamp.Screw lamp cover and turn On TV.

I've heard thiis is a fan issue that you need to replace an exhaust fan which is pretty cheap

when i got my ps3 it was already playing games in HDMI. but for some games, such as guitar hero 3, i had to go to options in the game and click HDMI and it has played in HDMI from then on
