TV shuts off after 30 seconds to a couple minutes. Red power light then blinks. Power cord must be unplugged to turn it back on. When TV is turned on, the picture is tinted white, but image is marginally visible. Also, picture has horizontal and nearly horizontal lines (almost banded). Sound is fine. Menu is functional but too blurred to read. Each video mode behaves the same. Other TV picture is fine, so cable appears fine.

Re: Screen white tinted, horiz lines, then shuts off
Not acutally a solution.
We are having this EXACT same problem; it started this week. Let us know what you are having done. I've called Toshiba and service reps but they are all quoting a price which is almost half the value of the tv. Have you been able to fix it? We are pretty upset since the 2year warranty recently expired. Obviously, it seems that others are having this problem as well. Email us: [email protected]

The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.
Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.
basic sony reset below
The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.
Turn off the television.
IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center
That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV. 2. Look at the power supply board..Its normally connected to the power cord.. 3.
After that,,try to look at the actual image of capacitors if it is
bulged on the top so that you can easily determine the bad capacitors.. 4.
After that,,try to replaced the bad capacitors using soldering iron and
soldering lead..replaced the capacitors only with the same type ratings
and value.. 5. Some of the capacitors not bulged so its better if have a capacitance meter
power light keeps flashing and the tv won't turn on. If you unplug for a
minute and hit the power button it sound like it is coming on then it
shuts off and the red power light flashes slowly. The TV is a Panisonic
1080i HDTV, about 6-7 years old.
This tv have a power supply board is the causes and the problems.Ur tv power supply board finally gave out and not supply the right voltages to the tv system anymore.That the board,where the tv power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Hi, KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down. This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color. Solution for your tv problem is Screen Voltage adjustment that can be done easily if you are handy with electronics stuff repair. Let me know your expertise level to guide you more and if you feel unconformable by tv repair then local tv repairman will help you to adjust white balance in tv. Hope these info will help you. Let me know if you have additional questions. Thanks.
The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.
one thing you may try first is disconecting the tv from ac outlet and plug back in ater 20-30 seconds, try to power back on. If nothing happens you're not doing anything wrong it might be that the tv needs circuit repair, the light blinks and you get sound indicateds a possible deflection board problem either horiz out transistor or surrounding circuit if you only get the blinking light no pix or sound could be also indicator of defl circuit failure or switching mode power supply acting up.hope this helps please let this site know if your question was answered.
Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
