Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Sony projection tv Model kp-61h510

Hello, My tv periodically turns really red and has arched red lines through the picture. It comes and goes and the only other problem I have is the tv almost never comes on with the first push of the button, the sound comes on but if I turn the tv off and back on again it always comes on the second time. Any help would be great thank you, Dan

My KP-51HW40 clicks off after running for a period. The red power light blinks when it goes off but screen stays dark. When TV is shut off for a while it restarts and runs fine. The "On"...


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.

Blue Horizontal arching lines, Blue hue at power on


if you take the front cover off the tv, you will see 6 little nobe, the top 3 are focus, bottom 3 are brightness, should be RED-BLUE-GREEN in order from left to right, find the one that is blue, turn it down a quarter turn, should fix the problem

ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN.

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
