Hello. The chirping probably indicates a shorted transistor or diode, and the burnt smell usually indicates a blown capacitor or a burnt resistor, or multiple damaged parts. I would have to see the TV to be of any further assistance. Sorry I couldn't be more helpful. Good luck.

It's possible the mirror has dome dust on it from jostling during the move. W dried water spot will do it too. The front screen will come off by removing the screws on the bezel. Be extremely careful cleaning the mirror.Any scratch by a cleaning cloth (never use paper) will permanently ruin it.

Try putting TV on Chan 3,4, 21, or 62.

Hi Glenn,

Just change your region into SECAM / PAL / NTSC on your TV to change the color of it.

I hope my solution may help you.
Thanks for using Fixya...;-)

This usually is indicative of the EXTREMELY HIGH VOLTAGE anode connection somewhere between the flyback transformer and one or more of the crt picture tubes or the splitter. Being that this circuit has a running voltage potential of over 30,000 volts if you are not familiar with these YOU CAN BE KILLED messing with it!!! What happens is that there is a breakdown of insulation over time usually from dirt or other environmental contamination. Usually a good cleaning and replacing the HV anode wire that has failed. (hint) it will be the one that the "ticking noise" is coming from. The ticking noise is actually the high voltage arcing to the chassis/ground.

Be careful!!!!

My fixing it directly to the cord

Akai PT5492S 54"... | Answered on Sep 15, 2012 | 24 views

might just be the fuse (a 1.5 inch glass tube inside the back panel by the power cord ,)
make sure that THE TV IS UNPLUGED,

if its not that- its a transformer and not worth fixing

sorry but I'm taking NO RESPONSIBILITY if you zap yourself
i'm only telling you what I would do to check it without killing myself

If it does not do it via the rear audio and video jacks (a DVD etc) problem may be a bad tuner or even a bad connection on the cable wire or fitting at rear of set--move the cables at connection points with set on to see if a reaction.

If not from DVD etc there is a way around this issue.

A DUPLICATE of another question listed here--see my other answer--touch that it gets directly into your body and is toxic.

This set with Akai is actually made by Samsung (they own and use the Akai name).

If lamp light etc and you have heard a cracking sound it may be the color wheel.

You can remove the lamp and look where it faces--look and the wheel can be seen----is it shattered or missing plastic pieces?

The wheel commonly fails in this fashion and is turning at over 12,000 rpm. The set will detect if the wheel is stopped or moving too slow and just what you describe will happen.

Wheel is widely available and You Tube has video instructions for replacing them by model number.

Akai is listed here which is Samsung---sounds like a convergence problem.

press "make a comment button" here and confirm the brand/model and what is wrong.

No picture and no sound? start by checking the fuse connected to the power cord.

I have had a few of these with similar symptoms. In one case the set had a coolant leak onto the circuit board. The way I found the problem was to unplug the power and removed the front cover.(most models you can remove speaker grill and access panel) Make sure power is unplugged. When I looked in using as much lighting as possible I was able to see small puddles of coolant that had dripped onto the circuit boards from the picture tubes above. The other one as I recall had an arcing picture tube which caused a screeching type sound seconds after plugging in, then it would go into protect mode and just have a blinking light. I'm sorry to say but in both cases it was deemed unrepairable due to expense or lack of parts. Although, in many other cases I was able to clean the leaks and circuitry to restore power. Keep in mind this is just an educated guess. Good Luck, Russmann.

I'm sorry that the TV is losing color. Please follow the troubleshooting steps and check the operation:
  1. Please make sure that the connections are secure and proper.
  2. Try connecting a different video source like DVD player or VCR and check the operation. If it works with another device, the issue might be with the input device currently.
  3. Also try connecting the device to a different port in the TV if no other devices are available.
  4. If the issue persists, try with a different cable.
  5. Perform a power resetting and check the operation. To perform the power resetting, unplug the TV from wall outlet for more than 2 minutes and then reconnect it.

If the issue persists, Picture tube of the TV may have to be replaced.

Thanks for understanding. Please let me know if you require any clarifications/additional help.

Hello benjapoo62,

Welcome and thank you for using FixYa!

You need to have the soldier joints around flyback transformer checked for weak spots. Then have the transformer tested. They should also test the backlight bulb inverter board. Just in case the set is on, but goes dark once the inverter board heats up.
If I were doing your repair, i would spend a good day testing these componants and be prepared to replace them.

Have a great evening!

Replace the lamp, after you replace the lamp reset the lamp hour meter good day and best regards.

The blue is usually dimmer than the other two lens; what I would suggest is try to look into the lens with the set on; BE CAREFUL AND NOT TOUCH ANYTHING INSIDE THE SET.

If the red and green show a picture but the blue looks like a floodlight you have bad Glycol in the blue tube (common in these sets).

If all have a normal picture remember to wipe the lens clean at the top; do not try to take the lens etc apart.

Before you rate this information let me know what you find.

The PT5492S doesnt have a color wheel since that model has three CRTs instaed of the single lamp. Double check the model number and I will assist with the issue.
