Question about Toshiba 36A43 36" TV

Picture disappearance & tv turns off

We have a toshiba tv, about 3 years old. Sometimes Tv turns itself off(on standby). When you first turn it on you get sound straight away but takes time for picture to appear.It also loses picture after a few hours and may come back on its own later(still getting sound). We have also noticed strange colours & sizes on screen. It is kept under window (in sun)could overheating be problem?

Re: picture disappearance & tv turns off

It sure sounds like you have a classic case of bad solder joints. Resolder all the connections on all boards.

Hi, I have a Panasonic W32D2DP its about 5 years old. It worked fine until about 3 weeks ago. It started cutting off and going to standby. It worked fine after for a few more hours, then would do it...

It's going to be cheaper to buy a new TV. Once you get this problem solved, another one will pop up. The parts for a TV that's 5 years old are not going to be cheap. Most TV repair shops stop carrying parts after 4 years, & the manufacturer stops making them after 7-10 years. With a semi-major purchase like a TV, it's best to purchase an extended warranty. ipmart. com offers a cheap repair manual. You'll be suprised how expensive repair shops can be when it involves "out-of-warranty" work.

Picture on 15 year old Trintron comes on briefly then goes black

if the sound goes out its not a tube problem . a bad tube would have no effect on the sound .you problem (my guess) is in the power supply . a modern tv power supply has parts of it that stay on all the time unpluging it is not the problem its when you plug it in ! the power supply gets a JOLT . you might get away with it ,you might not . thats why we install surge arrestors on power plugs and with expensive tvs i recomend a UPS a power unit that keeps the tv powered even wnen the line power is out . thats keeps everthing in the sets nice and even ,so the tv lasts longer ... a modern tv turned off uses about 1.40 in electric a YEAR in standby mode , so what are you saveing if you send you set to the landfill early and have to buy a new one ? over 1.40 in electric ? . turn down you water heater or something else simple dont be blowing out you electronics for the sake of a few cents ..... good luck .... if this answer helped please rate a 3 or 4 , this high rateing will hepl keep me in the paid answer department . thank you

RCA TV, model number 32V550T. No picture but sound is fine.


this sometimes is quite simple to fix as it cud be a dry joint on the circuit board where the tube motor sits.

or it cud be the tube is on its way out, which wud be cheaper to buy a new tv rather than have it fixed

TV keeps turning itself on and off, onto standby

Throw away this tv?

Please check cold solder joints in main board, specially in vertical deflection area. Its problem of dry solder joints. Little solder work required to fix this problem.

TV turns off by itself after being on for 60 seconds

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.
