have the store fix it you need a tech that has the right equipment to fix that. Since you say you replaced the lamp I assume you mean a LCD micro projector not an LCD Flat panel. There is a piece of equipment that a tech should have that can be plugged into the TVs circuit board and it can fix the spots with an electric pulse. I have seen in done on micro projectors in the store that i work by our techs. So my advise is have the store fix it before your warranty runs out.

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means.
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

If you see bad capicators, just replace the ones that appear to be bad. There are many different types of capicators on the power supply and there are different part number for each one. The good thing about capicators is they almost always list the ratings on the capacitor itself.
Check the Voltage rating (V) and the Farad ratings (F, usually μF), you can replace them with any one that has the same ratings. Make sure BOTH of them match the old ratings, you can purchase at just about any electronics store that carries electrical components such as RadioShack.
