Indication Light On, Black Screen, Unresponsive

This problem has only been apparent for the last 2 months. The indication light occasionally switches from stable blue to blinking, without the interference of the remote control. The screen is a constant black, and will not respond to any functions on the remote (i.e. power on/off, input, etc.).

SOURCE: Red light power indication is on. When I push

Any sound? The problem can be due to bad 24vdc power supply due to bad caps or failed components, bad backlights inverter boards, bad main board. You need to troubleshoot it to really locate the bad board/s.
Please read my guide first so you will know what to look for inside.
Service manuals (one of these should match your chassis):

SOURCE: LG 37LG30 wont come on. Gives blue light, but screen stays black and no sound

Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Cruise control does not activate when turned on,brakelights work pedal is not stuck on.when starting vehicle instrument cluster illuminates speed control lamp

Brake lights are not an indication that the cruise control works. The brake light switch and the cruise control switch are usually 2 different switches. Physically inspect the brake pedal shaft.

Hello, I have a 2001 gsxr 600 that won't start. It sit for about a month and ran fine the last time I rode it. When I turn the key to the on position and the panel lights up and the rpm's tach out then go...

Well...normally with most bikes...neutral indication is only needed to start the bike while its on the sidestand.
Even though it is in neutral because it doesn't indicate it, you need to have the sidestand up, and the clutch lever pulled in to attempt a start. Make sure kil switch is set to Run.
If it does start....because of no neutral indication, it should kill the engine as soon as you try to set the sidestand down.
If it will start and run....to look for the neutral indication issue, you need to trace the harness going to the neutral switch (or gear indication switch depending on make and model).
Any chance of rodent damage to wiring while stored....just seems odd the neutral light worked before...and now it doesn't. My experience is with Yamaha, and they usually grounded the neutral circuit at the switch, so you need all wiring connections secure and no wire breaks to get neutral indication, and satisy the interlocks.
