2) AC cable for the TV into the power outlet, blue light comes on and I hear ding sound from laptop indicating that the laptop recognized the TV. (The laptop already had the reqd USB driver). The TV still doesn't power up.
3) I start the Mtk_DL_V1.4 A_20060601.exe selected com5 as the port. I start step 1. This time it says erasing the flash and the step 1 is complete.
5) I disconnect the TV power cable, wait for another 10 sec, and then reconnect.. ding sound in laptop.. I select com5 port.. again repeated press in power button.. nothing happens.
6) I start step 2 and the step is complete.
7) I disconnect everything, wait for 30 sec, and then switch it on hoping for miracle.. it powers up.. I am saved for the time being..
Good luck !

This was a completely bad idea, since now I can't even turn the tv on.
I tried to rerun the same firmware using an xp pc, but that didn't work (obviously) and the tv is still with a blue light and won't turn on.
I wanted to open up the tv and check the hardware itself, but after removing the 10 screws that line the back of the tv peripherally, there is a snag somewhere and i can't separate the back and the front (i did notice 6-8 additional screws that connect the front part of the tv to the metal support inside the tv, but I haven't unscrewed those yet). I'd like to see if i can change the capacitors (if they are blown) or just try to change the power board altogether.
any suggestions on getting the darn thing opened up?
First, which model TV do you have exactly?
. It might have nothing to do with the power board at all. What was the problem or reason for you to try reflashing it? Was something wrong, did it have the permanent "blue light" before your reflash? What was it?
Second, I had the permanent blue light after a power on/off/on/off for 45 minutes power outage. I reflashed mine, and it fixed it completely. It was NOT a hardware problem. IF you used the wrong firmware, you MIGHT have completely bricked your tv set. However, mine was bricked due to an power wave outage, and so was kousikb's, who I linked above with slight edits to simplify his post on how he reflashed. I followed his pattern, and it also worked for me.
IF the reason you had a problem was due to the permanent "blue light", I suggest you put it all back together, find the proper
firmware, and reflash it with a older WinXP pc using the proper steps until it "takes". Disconnect that pc from any web access while you are doing it. Also disable any anti-virus, or any TSR programs that are running in memory. IF you can't get it to take a new flash, you might be SOL completely. It's basically a computer masquerading as a tv set. Firmware should NEVER be reflashed unless you absolutely must. As you see, it can be a dangerous endeavor.
Please note: IF you have the 537H-b12 model (2 HDMI ports, I have the b11 model, which is slightly older, and only has 1 HDMI port) you might be screwed, because I don't think anybody ever got a new firmware for that model before Olevia went belly-up. I can't remember for sure as it's been a while. IF they did, it will be posted in this very long thread. IF you find a post where the person says they have the particular firmware you need, I suggest you PM them directly. I don't think too many people are rechecking this thread anymore.
Good luck, I'll try checking back several times over the next couple of days, and see how it goes for you.
