Toshiba 40RV525R 40 in. HDTV - Answered Questions & Fixed issues

Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

you probably have voltage problems , you might want to check the source, the componenes , such as capacitors and ic

I have three places maybe that will be able to help. TigerDirect, Full Compass, and last "Radio Shack"

Did it just start doing this? I don't think the issue is of one related to age. Do you have it placed next to a floor register or some such product that produces heat? Look on the backside of the tv where the vent bars are, and see if they are coated in dust. Have you called the manufacturer to ask about it? Sometime by asking at work or talking to friends you can find the answer, or get one of those :light bulb moments over your head.

try working it the other way, input the code to work your toshiba television from the direct tv remote.

Did you find any solution for this?

I called Toshiba for this TV model "40RV525R" and they said the pedestal stand for the t.v. to stand on was an m5, product # 75012791, and the length was approx 20-25 mm

Hi Gordon,Did you fix this problem? I have exactly the same model with exactly the same problem. I've checked the capacitors on the PSU board (as suggested in one of the responses above) and they all seem OK. If you fixed the problem, I'ld really like to know the solution. Many thanks. Regards, Harry.

Check for it at its main power regulator board.

Have you replaced Batteries in the TV remote. also do not go back to far with remote. 25 to 30 feet is the limit. Good luck.

no way to fix and it's haz mat so you can't even put it in the trash technoligy has gotten so go and so hazardes

Dear fleeper63,

• First, make your the batteries in your remote have not run down. To do this,point your phone's camera(after starting the camera app,obviously) towards the transmitter on the top of the remote (a small,transparent bulb like thing). Then, press any button on the remote and at the same time look at your phone screen.If you can see a flash whenever you press the button on your remote,then the batteries are working fine and it is probably a fault in your TV. Take the TV to the nearest service center and get it checked by qualified personnel.

If you can't see any flash,then simply change the batteries in your remote or request a replacement from your local agent.

Sounds like a mainboard problem,your tv may need a new mainboard

hi,
As it is a fault caused by the lightning it is better to consult some one experienced rather than doin it by Yourself. Its powers supply have problem. If you are able to do the same then remove the back cover. then check the input fuse in the power supply. If you find the fuse faulty then check the MOV (Componet used for High voltage sure protection, MOV have a voltage range, if voltage above its rating occurs it will get shorted and blows the fuse preventing from further damage to the power supply.). It will be near to fuse. It will be placed in Paralel to the Phase and Neutral track after fuse. You can check the same is it faulty very easly. Insert the new fuse in position, using multimeter (in ohms range) check the ohms between the two pins in the power cord. if its shows a low ohms ( bellow 1K) then the MOV is faulty. After replacing the MOV you have to check the ohms Again. if then also it shows low ohms. then you have to replace the bridge rectifier. first of all check the fuse and MOV. picture of MOV is added below.

ok

Either by the remote control or by the power switch on the TV?
The power supply may have died but check the AC outlet first to be sure, otherwise it will require you to open up the TV and do in-depth troubleshooting.
Please read my guides first if you are goping to do DIY repair:

Hi,
Unplug your unit for 1 hour, before you power it on, press and hold the power button for 1 minute.
If the symptoms still there, then this is an indication that the power supply board was gone to malfunction. Some voltage surge protector is not a 100% reliable because it depends how high is the voltage surge coming from the source and if the design can handle such surged to avoid damaged to the unit. In your case, obviously the surge protector doesn't react efficiently.
Yes this kind of symptoms is quite fixable but needs to send it in because I've suspected that not only the power supply board was faulty but also the mainboard because your direct TV box was also fried which is connected to the TV.
Check if your unit is under warranty/extended warranty, avail it because the manufacturer will fix it for free, but of course don't mention that the unit was fried due to storm. If not, ask for an estimate first for service fee ($300 more or less depends upon the shop) plus parts to have an idea whether to send it in or buy a new TV.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hello

To remove the black bars from the top and bottom, press the [FORMAT] or [ASPECT] button on the remote. The option available to remove the horizontal bars is Zoom.

OK.
