Hisense 40 inch tv wont turn on

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set isopened at least look for puffed up and bad caps like in this photo5_21_2012_3_41_35_am.jpg5_21_2012_3_42_12_am.jpg

Hisense tv

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions. Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy

I got a Hisense TV

Hi there,

Unfortunately, I'm going to need some further information from you to answer your question. I think the model number you provided is actually the model number of the Hisense remote control and not the model number of the TV. The correct model number should be located on a sticker on the back of the TV. Please can you check this and correct if necessary. I'm not saying you are wrong, but I cannot find any existence of TV model number EN-30505A.

This is where it gets a little confusing. If that is the model number of the remote control then you should be able to disable the childlock by pressing the lock/unlock button on the remote . . .

Please can you reply to me with the following information:

1. The model number of the TV;
2. Do you have the original Hisense remote and is it working?
3. The approximate age of the TV (to assist with identification in the absence of a model number);
4. The brand and model number of any remote you are using with this TV;
5. Is there a MENU button on the front or side of the TV and does it open the on-screen menu?
6. Is there a MENU button on any remote you are using and does it open the on-screen menu?
7. How did you engage the childlock? (if known)

If you can let me know these details, hopefully I will be able to solve your problem. You should note that some Hisense TVs can only be unlocked with the original Hisense remote. It is possible to lock and unlock them from a universal remote, but unlocking them this way is dependent on remembering which buttons were pressed to lock it. Obviously this isn't possible if it was done accidentally/unknowingly!

Regards,
BElectric.

How to troubleshoot the tv with sound on and off?

1. step Unplug it Wait about 30mins, you can try pushing as few buttons in the meantime (to empty the capacitors) 2. step Plug it back in and test, if it's a newer model it should have a "reset to factory settings" option. Try that.
