Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

Open Question

Unstable video Two months ago the TVs picture would have slight wavy lines just at the top section when powered on. After about a 15 second warm up they would go away. Now the TV picture is totally unviewable for about the first 90 seconds. I have access to Toshiba parts but I'm not sure what part I need.

    About 2 months ago, Toshiba 42H83 started taking at least 1 minute to "warm up" to get a clear picture. The "warm up" time has now increased to 4 minutes. Doe's anyone know what part can be replaced to fix this problem?

    I have a 42H82 model Toshiba that that has wavy lines and can not be viewed for about 5 minutes, then the picture clears up. What do I need to do to fix this problem? thanks.

    I have the identical problem with my 42H83 and have read about many other owners who also have this problem.. This is obviously due to a defect in design and/or manufacture. This is the last Toshiba product that I will ever purchase and the last that my business will purchase... and that's alot of business.

Wavy horizontal lines across the screen

It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

Hi, I purchased a Sony Bravia model #KDL-52S4100 two years ago. About 7 months ago when the TV was turned on there was no picture for 15 minutes or so, then when you turn it off and on again half a picture...

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for 5 mins, then try.

If you aren't tech savvy, this unit needs to go in for repair.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Video distortion

You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Picture Jumps/flashes for first 5 minutes

There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.
