I hope this section is opened to contribution.
I have four of these units and they all work reasonably well for the last 6 months that I have had them. All my setups have plenty of ventilation and one thing I find also important is that I use an accurate bubble level to make sure the DVDR recorder is sitting perfectly level. You can use small card board/paper shims to level the unit.
Below is a cut and paste, with some italic remarks added:
Issue: (1) Random jitter in the image, randomly while viewing or recording. (2) Green tint, randomly when playing and/or recordings. (3) Mono tuners, not stereo. The stereo is only using RCA audio (red/white wires). (4) Overheating.
How common is it? (1) Random, yet very common. Tends to happen more on 1163 or later firmwares. Note: that is a USA R1 number, other region firmware numbers vary slightly. This seems to be a problem more on 5001, 5005 and 5006 units. Or ones using those mainboards. (2) This issues seems to infect only the newest LiteOn models (like 5045, 5007) and ILO models. It is about as random as the jitter, not everybody sees it. Latest firmware may alleviate some of the green hue. (3) While there may be a couple stereo models, most are mono. (4) Very common, especially on the models that have no fans, no heatsinks, and no air vents, or combination thereof.
Can it be fixed? (1) Yes. Downgrade to 1143 or older firmwares. (some units can not be downgraded after a certain recent firmware). The work-around is to hit SOURCE a couple times to cycle back to it. This can also be caused by overheating. (2) Recent firmware upgrades are reported to correct this problem. But since the nature of the error is random, this fix is unlikely to fix every unit exhibiting this problem. Try it, and cross your fingers. (3) No. This is the hardware of the tuner. It is dual-channel mono, so it's not like you'll only get audio from one speaker. Since many tv shows are mono, especially anything syndicated, this will not be noticed by most people. Many have used cheap stereo VCRs as a feed into the LiteON RCA inputs (4) Yes, with some custom work. Simply removing the cover will provide decent air to keep the unit from failing. Further work yields even better results, such as -A- drilling holes in the side of the case (remove the cover, do not drill into the unit while it is assembled), -B- cutting a RAM heatskink in half with a hacksaw and using thermal tape to attach it to the LSI chip, -C- installing a small fast fan to blow air across the motherboard, and out of the drilled vent holes. This will also correct most jitter issues, if the fan blows LOTS of cool air across the heatsink. This setup may be slightly noisy, but no worse than a computer, ceiling fan or air conditioner, which most people have running anyway. Some of the oldest firmware is also known to run hotter on the chips, too much code activity going on in them.
Will it break again? This question is moot for the first 3 issues, seeing as how none of them can be fixed. Just work-arounds, hopeful patches, or hardware limitations. For (4), this fixes the cooling issue permanently, and often corrects the jitter issue most of the time.
Related myths: The drive model affects the jitter or heat. This is simply not true. The drive model has no effect on any of the LiteOn flaws.
