Hello Mike,

Note: Working on a TV can be difficult and dangerous due to the high voltage circuits inside. Always remember to unplug any TV before trying to service it and if unsure of the proper procedures, seek the service of a trained professional.

I would like to assist you with your television. The three blinks denote the lamp door not closing properly or a failure of the switch. I have included an exploded diagram of the assembly, for purposes of checking the switch, at the end of this reply. Remove the lamp door and look carefully at the right hand side where the plastic lever engages the housing. There is a little piece of metal that is the actuator arm on the T board micro switch which is the lamp door safety switch. After you have found the switch, re-insert the door and verify if the lever makes contact with the switch and pushes it up. If it does, attempt to turn the set back on. If it is still in failure and you have verified that the switch is pushed up and the arm is not bent, the T board has likely failed and that will require a technician to replace if memory serves me right. I believe that the ducts on the back of the fan assemble cover the back side of the T board and that is where the problem with replacing it lies, the ballast for the lamp is mounted to the air ducts and it is extremely hazardous to work with due to very high voltage and current and I cannot advise you on it's disassembly.

One thing to note is that the lever engages with a click and it can take quite a little pressure to get it to fully engage. It should sit horizontally level when fully engaged.

Please reply with what you find with the switch and it's condition and I'll be happy to assist you further.

Hello and good morning. Well Jerry that micro fish print did help me and thnks for that. I think the problem is that t board micro switch. The reason I think so is because there's no piece to catch where the door engages at. Is this part available? Also I would like a more detailed picture of just that part(t board micro switch) so I have something to compare it too. Thanks again

Hello Mike,

I found an image of the T board, there are several shown, but I think that the attached one is accurate. The one shown has a small white plunger, but I have seen them with black plastic and a small metal bar instead. Is the door lock engaging fully with a click? It should sit horizontal when fully engaged. The plunger or rod will be at the top of the slot on the right side where the lock engages.

Please let me know what you find.

Good evening Jerry. I looked at the attatched pic sent. Is the part where the arrow points to it? I'm still clueless with this. If this doesn't work I may be forced to call in a technician.

Hello Mike,

I have added a red arrow to the plunger on the switch, this is the point of contact.

Well Jerry it seems that the bar on the t switch is missing. I need another one. It doesn't seem very difficult to remove and reinstall. Can I order it?

Hello Mike,

I have attached a link to the part at the end of this reply. I cannot emphasize enough, the care that needs to be taken if this is close to the ballast. Leave it unplugged for several days prior to working on it!

Hello Jerry. Well finally got the t board switch and installed. I still have the same problem. I noticed that the lamp door (101 on the illustratiion) is missing a small piece that pushes the bar in place.
