Re: Replacing an LCD screen from a modern TV
Over the last five or more years I have checked prices on LCD panels for most major brands. No luck finding a good replacement (price) if they are even available. Manufacturers don't want to sell panels for repairs. [U]Some[/U] panels are available for in warranty failures but most panels are used to make a new TV.Re: Replacing an LCD screen from a modern TV

Dell Inspiron 17R-5720 Again! Panel goes to snow (hash?) or lines. Picture!
Dell Inspiron 17R-5720 Again! Panel goes to snow (hash?) or lines. Picture below (if I did this right) Bad panel or HDD?
Very intermittent,this happened almost a year ago too.
This is my PC. The last time I took it to a local PC shop where they let it run and "tested stuff" but found nothing wrong. It has been working good until a few days ago when it started again. It froze up with garbage covering the whole panel. Usually it looks black & white but sometimes it has colored horizontal streaks like this picture. I have to hold the power down to turn it off, then...

Re: Toshiba 46L5200U LED Replacement Help Needed
More bad news for this model. Here is a link from the Toshiba forum....
[url]http://forums.toshiba.com/t5/Televisions/46L5200U-picture-has-no-backlight-but-sound-is-present/td-p/528349[/url]
I haven't found any new led assemblies for these and it looks like a partial repair of any current strip will be a temporary solution because it's likely that more LEDs have already been stressed. However a low (< 60) backlight setting is allowing two 46L5200U models to [B]stay on[/B] that I have worked on. The...

Re: Toshiba 46sl417u main board issue
Do you mean the 2.9vDim on pin#1 (PJ860 to J1), pin #10 on CN90 (main) ? Is the resistance low on that DIM line with the TV unplugged? Unplug CN90 and check pin #10 on Main. A low resistance = bad main. This model has had power supply problems.... so is the standby voltage low or unstable (CN90 pin #4 = 5vsb on main)? If yes, then you might have [B]power supply[/B] problem. Some kits are available.
PJ860= [B]Power Supply[/B]

1. <2.9V Dim
2. <5.2V BL On

Re: Sanyo DP42840 P42840-05 set wont turn on
The DP42840 Sanyo series have main board problems and new boards aren't available. Some kits are available (check ebay) but the smd IC's are difficult or impossible to replace without the right equipment. Problems are usually related to data corruption on IC5750 but other components can be bad too.

Re: led46c45rq no backlight
Need more information.... maybe you have a short that is holding down secondary supply voltage? Does the standby (power supply) voltage change if you unplug the main board?

Re: Treadmill motor not working
A working DC motor will "generate" DC voltage. With the motor still mounted in the treadmill... unplug the motor wire harness and only connect a DVM to the motor power wires. Walk on the treadmill. If the console is working, your speed will be displayed from the spinning front roller (magnet & lief switch). If the maximum treadmill speed is 12 mph and max motor voltage is 120vdc, you should see about 30vdc on the DVM when walking at 3 mph. If the voltage is considerably less than that.... you have a bad motor.

Re: Vizio E420VO not powering up at all
Do you hear the hum with "mute" on? Is the hum coming from the speakers or is it radiating from the power supply or panel?
