Question about Sony KP-53HS10 TV

KP-53HS10 Red blinking light/screen turns on and off

My TV is a 2000 model and a couple of weeks ago the standby light started blinking 5 times. A week later the screen blinked on and off a few times and now it will do it for up to a hour. I'm not sure, but it appears that the color is not right and when I turn the TV on now it seems to take a lot longer for the screen to appear than it used to.

    there are 4 holes at the bottom of the speaker grill but are covered by the mesh and I can't find a way to get in without ripping the mesh. Is there some trick to it?

    Thank you so much for your help. I am still apprehensive the light will start blinking again but so far so good. I finally figured how to pop the screen off and once I adjusted the buttons the picture was working although the light was still blinking so I turned the TV off for 5 minutes, then unplugged it for one more minute and then turned it back on. The results are that the TV was on for over two hours and the blinking light never returned nor did the picture turn on and off. I will follow up with an additional comment tomorrow after running the TV for several hours to let you know how it goes. You saved me a lot of money. Thanks again.

    yes, i had the exact same problem. we took the front off. adjusted the top 3 screws as outlined in this guide. the procedure fixed our problem and the 5 flash error went away when the screws were correct.

    also since this tv was about 9 years we decided to pay it some extra care. we took it outside and removed all panels, cleaned the mirror, the

    projectors, and screens. we took air compressor and blew all dust out. wiped the set completely. when it was all back inside and cleaned. this TV looked and viewed like it was when i first bought it... Thanks so much for this money saving tip... we were considering a new tv set. now i hope to be viewing this beauty for many more years to come.. again thanks...

    I'm having the same problem with the 5 flashes and picture going in and out. I understand what was said about adjusting the controls behing the screen....if I could just get the screen off. I see no screws at the bottom unless you're talking about the three underneath in the middle. Please help

    I've had the same problem since I moved my TV.

    This solution worked great the first time I tried it.

    Thank you for posting it!

    I will add that with my unit there were no screws to remove the speaker screen. It had grometts holding it on so I just gentley pulled it off. After that there are four 4 screws that hold the control module on and 4 that hold the black particle board access panel on, then you can see the module on the right hand side of control module.

    Do the adjustment as stated, try not to go too far because the TV will make a popping noise and make you think you just blew it up.

    I know because I did just that. lol

    I just backed off the adjustment counter- clockwise turned off the TV and did the adjustments again. I worked just fine.

    Thank you again for this fix. I was going to buy a new LCD TV for Christmas and this saved me a few months.

When a Sony does what you explain it usually only needs it's screen controls adjusted. This would be the first thing before replacing parts or any other trouble shooting, To do this you have to remove the speaker grill, there usually are two screws down low that are covered by plastic covers, once these are out the bottom pulls forward and slightly down. Then there will be another cover, remove that. Now you should see the inside of the TV. Near the front there will be a control ruffly the size of a pack of cigarettes and have six controls on it, Three are for focus and three for screens, Next find a video source that has no input, this simply means change to a input that has no signal, and gives you a black screen. Next simply turn the screens clockwise till a faint glow and retrace lines appear, then turn it back down till the color just disappears. Do this to all three, then you can re-glue them with fingernail polish if you want to.
Thats the simple way to set the levels on the CRT's, Sony's have a circuit that mutes the video until all the voltages are within a certain range, if the voltages are too far off it will give you the five blink error code, now if does not fix the problem there are other problems, This can be any thing from a weak CRT to a capacitor failing. And on a final note it is best to let the set run for at least 20 minute before doing this adjustment to let the voltages stabilize, and it is best to check it after another twenty minute to make sure it stayed

Standby light stays on and the tv will not go on

Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.

Grey Screen with 480p signals (or higher)

I've had a KP 53HS10 for close to 8 years I think. 4 years ago the picture started blinking after long use, then more and more often. I had a repairman come and replace the tuner card (that's all I know about what he did). Now that I finally have HD from cable, I've found that 720 doesn't work and 1080i works, but the picture blinks on and off apparently struggling with some inner problems. Everything looks great, for a second and then it blinks. The red light blinks 5 times repeatedly while this is going on. I called SONY 5 times means get a repair man. I searching forms like this for help as well.

Sound, but no picture. Standby light blinking 5 times

A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks
