Question about Toshiba 57H81 57" Rear Projection Television

Open Question

No Picture I was just given this tv for free. I figure whatever is wrong with it will cost less than a new tv, so here goes. There is no picture, and the audio works when a dvd player or something like it is plugged in. The red light is not flashing, no weird popping or clicking either.

    I checked everything, and I couldn't find any lack of supply. Could it be my convergence ic's? I would really hate to buy new ones just to find out there isn't any need.

    It'll be a day or two, my dog knocked my flashlight over, and now I fuse F470 is blown. I will have to order one (really sucks having to order such a small part) so I'll get back as soon as I can.

    Out of curiosity, since I have a little time to waste on this now, what outcomes would there be dependent on the supply voltage of the h.o. transistor?

You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?

Most likely a power supply failure although the flashing of the LED a fixed number of times may point to something else such as a lamp failure. If you can find a forum for this series, you may find a Panasonic tech who can give you a better read on this.

TV no longer getting picture, just sound


This is due to a fualty logic board inside and it needs to be replaced, Also the power supply that send the power to this logic board is also suspect since you turn it on it stays on for 2 secouns or so then goes off.

1. Check power supply unit (you may want to dust it out as well, check for buldging capcitors.

2. Check logic board this is what sends signals to the LCD ( we would call it a video card).

3. if you cannot do this yourself it will not cost much for it to just be looked at and diagnosed before havingto go out a purchase another TV.

Keep in mind I am going by the information you given me and would expect a rating on the information only so please rate Accordenly. :)

Sony KDL-40V3000 standby blinks 13 times.


A service technician arrived at my home this morning and infromed me that 13 blinks indicates a bad LCD panel. His quote to repair it was approximately $500 more than the TV initially cost. I contacted Sony support directly, and they have agreed to replace the TV, since it is less than 30 days out of warranty. The KDL40V3000 has apparently been dicontinued so they are replacing with a KDL40V4100(factory reconditioned). I know this won't necessarily help others with the same problem, but if your warranty ended recently enough they will probably work with you to mitigate the expense.

Sound but no picture


Hello Dabizot,

With the price of the new tv's, I would recommend getting a new tv. It's only a 19" and you can get a flat panel 19" for less than $ 200.00 It may cost you $ 100 plus to get it repaired along with any new parts. If you want to spend less money try looking at the yard sales, people are always selling used TV's for cheap.

Sony kv-32v42


Your two options are to take it to a service shop, or the more likely and probably more cost effective option is to purchase a new Television. The newer model will have a far superior picture quality, cost less per inch of viewable area, and likely have more features than your prior T.V. as well.

good luck

No picture but have sound


RDD6 - I had the same problem with my AVT-1498. Took it to the repair shop who told me it would cost hundreds to repair. I figured I could find a replacement crt for less but was wrong - they don't make these tv's anymore, and really don't make any 12v crt's anymore period. So I decided on a 15" 12v ready LCD model which fit the hole where the old crt TV use to be. I needed to rig it to hold the LCD bracket but that wasn't too difficult. Then just hooked the wires back up. Good luck with your situation.

Has sound, no picture, just color


usually if the tube has gone you will get no sound and all you will get is the telly on standby so the best thing to do is take it to repair shop and they should tell you for free what is wrong but usuall it costs more to repair than it does to buy another one sorry i couldnt be any more help
