Olevia 537H digital tuner problem

I have the exact same problem with same symptoms. It was purchased from Target during their Black Friday sale in December, 2006. In 2007 I had the mainboard replaced under in home warranty to correct the static electricity pop that many people experienced. Then in early 2009 the digital tuner not working problem started. At first I could power off the set completely and upon repowering up it would work again for a while, but for the last few months nothing would get it working again, and yes I tried the "Bright Room" suggested elsewhere. I purchased a DVD recorder with a builtin NTSC/ATSC/Qam tuner (Panasonic DmR-EZ28) for $230 and hooked it up via the Composite jacks (HDMI would work also) and all now works, although the channel up/down function is quite slow. I was under the impression that the 537H came with a 3yr warranty (1 yr in home, 2 additional years parts) but when I contacted tech support to get a new mainboard sent out, discovered that the original Syntax Brillian company went bankrupt and service is now being handled by a company who says only 1 year warranty on all Olevia HDTVs. Replacement by them in your home is $318 and only a 90 day warranty on the service. Only other option that I can think of is use a cable or directTV settop box interface and connect it via HDMI.

If anyone can find the original warranty with the 1yr/3yr wording, I'd try going back to the retailer and get them to stand by that and send out a new main board, else if the cable or satelite settop box won't work for you keep looking for a remote tuner similar to the panasonic's functions without the dvd recording if you don't want that. Some of the new converter boxes that are almost free with the $40 government cuopons might work if they have the composite as well as the rf output, but will only detect ATSC not QAM and you'd have to experiment with getting the proper aspect ratio using the Olevia's remote's Aspect control.

I consider this a work around more than a solution. I have tried several things to correct the problem. In my case, the digital tuner would sometimes work correctly, 1 out of 25 times maybe.

While studying the problem, I read many posts about speaker hum, non responsive remotes, and various other problems that all seemed to be tied to the backlight intensity. For whatever reason, the system voltage on the tv seems to be affected by how bright the bulbs burn. More power to the bulbs means more power everywhere.

Following that train of thought, I used the Lighting button on the remote and changed to "Bright Room", then turned the tv off/on. Voila. It worked. It has worked for 10 off/on cycles in a row. That is more than coincidence. The tv was/is warm, so that may be helping also.

Like I said, not a fix, and it may not work for everyone. The problem is almost certainly some component(s) on the main board failing.

Good luck.

I have an older model Olevia LT37HVS. I would only get a blue screen and if I wait about a minute the remote would start to work, but no video. If I go to the Menu Screen and try to go into the DTV menu, the blue screen comes back on and the remote freezes. I would have have to unplug the power to turn it off. When I disconnected the video card from the TV, the remote will work and if I use the HDMI port the display will work without sound. So try disconnecting your tuner card. You can use it as a monitor without sound.

I think I have the same issue. Power on, no digital channels, and auto search does nothing. I've read somewhere that the remote had issues and can send wrong signals. Took the batteries out from the remote, switch the TV on from the TV unit, and it works. Tried it couple of times and things are OK. Put the batteries back and the remote will work fine again.
Please try it and let us know so we know if the remote is the source of the issue.
Thanks
