No, thank god they stopped doing that years (decades) ago----the memory is stored in a Eprom usually part of another IC.

Not sure how you are connected but if you had a cable box hooked via the rear audio and video jacks on it to the set in same way you could bypass the entire issue---box would have control.

I suspect a bad board here......

There are three fans: 1)Cooling fan(on the optical block)part# 1-787-057-11 2)Ballast fan part# 1-787-081-11 3)Upper optics fan part# 1-787-460-11 Also make sure you don't have a noisey iris motor in the optical block (verify by adjusting the iris settings in the menu and see if the noise level changes)

SOURCE: Blue Dots

I have the KDF 42WE655 with the same blue dot issue and Sony upgraded me to the KDL 46V4100 for $375! I jumped on the opportunity.

SOURCE: Sony KDF-50WE655 will not power up. Red blight blinks 4 times

4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

SOURCE: Problem with Sony Wega 50 in kdf-50we655 light blinks 55 times

I fixed my problem by removing the lamp and vacuuming the hell out of the hole where the lamp lives and also getting all of the dust out of the rear ventilation grids with my vacuum. I put the old lamp back in and what do you know the TV has worked perfectly ever since. My lamp was over a year old and did not show any signs of hazing on the lens that you might see on a lamp that has a ton of hours on it. I just thought I would try to put it back in before I spent a couple of hundred bucks on a new lamp.
TA DA problem fixed.

Hi,
If its Sony KDF-50WE655 TV then its weak lamp symptoms like TV turns off and on automatically and work for 3 minutes as you mentioned.

I have a kdf-50we655 that has a blue blob and jjust wondering if its too late for sony to fix it


With all due respect, you're asking the wrong people. Only Sony can tell you if you're too late but my experience has been that they're normally pretty fair with considering out of warranty goodwill repairs.
Ask Sony and if they can't help then come back and ask about your problem on FixYa.
