TV will not turn on. IS not connected to a computer

Some people recommend trying to update the firmware via USB. Instructions here,

If it is a model 32C120U, there is a known manufacturers defect. This issue is cause by defective main board because the main processor is not well solder to the PCB or the e-prom memory lost the software data. Some time you can try replace the eprom memory on the main board (cost of the e-prom $15) or re-solder with a hot air gun the processor but 90% of the cases you have to change the main board, the cost is around $30 you can find it in these guy are super. To replace the main board is easy and takes not more than 25 minutes.

How do I solve a power up / switch on problem with a Toshiba TV model REGZA 37WLT68?

may be a bad Capacitor on the motherboard, or its a bad power supply board. upon disassembly look at the Caps (image posted) near where the power goes into the tv. Typically larger ones. if any of them look swollen or burnt, then that is your problem. it must be de sautered and replaced with one of the same specs. if all of them look okay, then you probably need a new power supply board, which should be seperate board from the main board of the tv, depends on the model though. Also, check all around the board, there may be a bad (watch) battery on the board or a bad (glass) fuse.(also imaged)

Difficulty turning on

while I do not have specific experience with this particular TV as of the moment of writing this, the complaint you have is a very common one accross the board.

it is caused by one of two things: bad power supply or bad main board.

When in the power supply it is usually (not necessarily) caused by electrolytic capacitors (cylinders with aluminium tops standing vertically on the board) going bad. If so then those can usually (again not necessarily) be seen with naked eye as bulging on top.

The same can be true for the main board, but capacitors there are much smaller in size and harder to see bulging; more importantly, when in a main board it is often a result of a cold solder joint, usually in a BGA array (solder balls under the ICs as opposed to solder joints of legs around the IC). That can be difficult to find and more difficult to resolve.

What you can do is open the TV and look at your power board.

If in doubt you can send it to us for evaulation and service if necessary. Shouldn\'t go above $80 total, possibly less.

Hope this helps!

I have atoshiba 32 inch television and the motherboard gone bad. please give me places were to find a replacement ?

Well it depends on what the TV model is.

For the 32AV502R in particular if you can't find a replacement main board or if you are not actually certain the problem is in the main board to begin with it may be worth checking the failure symptoms and proposed repair service offerred here:

Hope that helps!

The color contrast is off. The black color appears with a red tint, and the picture looks similar to a graphic comic. I have a Sanyo 32" flat screen.

The five times I ran into this problem on these model sets it was caused by bad main board three times and bad lcd display panel,(screen) one time, and bad solder connections at a connector on the main board the other time. You can try to search model number and board description for pricing. Chances are a repair shop will charge 100-400 u.s. dollars to fix this problem. Good luck with your new disposable flat screen.Russmann.

Toshiba 42WP56T TV made a crackle sound then lost picture. Sound works but no picture except small pixel like image on corner of screen What happened can I get replacement part?

More often than not, this is caused by faulty sustain boards. I would like you to take off the back cover and observe for faulty caps on the two boards labelled X-main and Y-Main. The electrolytic caps(will be cylindrical in shape and will have an X mark at the top)caps will be bulged, cracked or blown off if they are bad. If its ceramic caps you are bound to see some burn marks on the board near them. Look for any other signs of evident damage, and if you find any replace both of the sustain boards(should cost you around 150-200$) as these boards usually take out one another when they go bad.

I have the same problem Panasonic Plasma TV wont come.

Alot of times capacitors on the power supply circuit board will go bad. They will bulge/dome or dry up which will cause this problem. Bad caps dont hold a charge, which is needed to maintain a voltage. The circuit board is two sided which makes replacing the caps difficult, and the board can be damaged and have to be replaced. Taking it to a repair shop may be cheeper and safer then doing it yourself. Having two-six caps replaced is a lot cheeper then a new board.
