Does it only happen when you use your Xbox?

Try pulling the cable in and out between the TV and Xbox

no something has gone terribly wrong in the mother board of the tv. sparks cmon man, cant fix that

try with the factory remote press......menu, 7, 1, go-back, tv....... then press menu, 7, 1, go-back, who-input

Use the PRESETS button on the remote control. See page 9 of the manual here: http://tv.rca.com/RCATV/Assets/pdfs/36V430T_1616262B_IB_e-05.pdf

This could be a simple issue with the dome switches on the tv. Many times they will become faulty and can cause strange things like this, one common cause of the switches going bad is incorrectly cleaning a tv by spraying cleaner directly onto the screen and allowing the solution to drip down the screen, capillary action will take a few drops of the solution an deposit it on the switch board behind the switches, causing the tv to malfunction. Even though the power is turning on and off does not mean that the power switch is the one causing this. Without getting technical the design of the switch array can make any faulty button work another function. For example a faulty volume up switch can turn the tv on or off. All of the switches need replaced.

you have to clean all the water corrosion off with rubbing alcohol and a toothbrush, then any blown or water damaged parts need to be replaced, you probably need a tv repairman.

There is a problem with your power ic..U need to replace it...
Dont forget to rate

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

There is a problem with the pincushioning module. Thsi would have to be replaced by a professional.

Without seeing the actual set, I can only suggest some of the common things that can cause this. Based upon your description, I would first look for a poor solder connection where the AC cable connects to the board. Look in that area for any charred spots. Let me know if there are any. The bussing usually is arcing of the AC power.

If it is a code someone put in you will need to figure it out. If it is a factory code it will be usually 4 numbers such as 9999 or 0000

It's the copper coiled magnet on the neck of the crt closest to the front of the tube.

do you have and big sound system if you do the move them away from youur tv. or you sould just bring it to a shop it must be the picture tube

this set is famous for defective flybacks. part number is 262342. replace the flyback

Hi there
Press the "source" button on the TV's remote control

Good luck

The servicr is correct that the MAV board is no longer available, but what is the problem with the set? That board in mostly an input board. Please describe the problem, perhaps we can fix the board.

Dan

The fact that there is no sound is an indication that the regulator circuit is faulty. This set should get a detailed repair estimate. This is not easily diagnosed remotely without takeing measurements internally. If you can get the estimate and post the results here, I should be able to walk you through the actual repair.

need more info but it sound to be a cold solder problem,look at the circuit board closely for cracked solder joints. Resoldering any bad joints might just solve your problems, but be carefull there are very dangerous site inside a tv, if you dont know about tvs look for profecional assistances..good luck

There is a problem with the vertical circuit. If you are comfortable with soldering, you should be able to fix this yourself. Look for a small flat IC attached to a heatsink. It will be marked LA7837 or something similar. This is the vertical IC. Try resoldering the pins on the IC. If that fails to resolve the problem, replace it. Report back here if there are other issues.
