Question about Toshiba Televison & Video

Open Question

My Toshiba LCD TV, model no. 40RV52U, takes a long time to change channels. I've noticed this is the case with all LCD TVs in general but lately I've visited friends with LCD TVs that have a much faster response time. Is this normal?

Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

SOURCE: Toshiba TV fails to recognize HDMI input

If the tv does all those symptoms but after some seconds the tv works and stays doing the job. THen the tv has a slow microprocessor to recognice the different resolutions or video inputs.

But if the tv cannot do anything and stay aout of signal forever. send the tv to the waranty. (no waranty? you have to use the component input instead to have digital signal reproduced

SOURCE: Toshiba LCD TV AV500E Turns off then on every 5 minutes

It sounds to me that the Main board is causing the problem. But I would get in touch with Toshiba for a warranty repair. It has a one year parts and labor warranty. It makes it a lot cheaper for the pocket.
Good Luck,

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Why does the screen go black with a screeching sound?


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.

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 and type of your device, in the search box [at the top right] of the display window; to gather down all the posts related to your device brand. It will make surf easy.

Vizio LCD 47" switching channels takes very long


Has it always done this since you purchased it? Check the response time online for that TV, it may just be that it is a model with poor response time when changing channels. I've seen some value brand TVs that seem to take a full second or more to switch and go blue/black in between while switching.

Very painful to channel surf like that, so if you have a cable box etc hooked up use that for surfing channels instead if you can't handle the wait.

There's 4 horizontal white tiny lines appear on screen to make the picture become 4 equal parts from top to bottom with many horizontal lines. My TV is Toshiba Lcd(40RV52U)


You have failure/weakening in the vertical section , the retrace lines appear due to the change in the freq.
Check out small value capacitors in this section. confirm by shorting parallel with the right polarity. Unless you are familiar with electronics please do not attempt unless with help. the fault is not very serious and could be attended with low expense.

My toshiba problem.


You may have bad T-CON board, try cooling it with small fan blowing on the vents of the TV.

Vizio 32/DirecTV - slow to change channels


Some TVs switch faster than others, plain and simple. I went from a Sony LED to a Sanyo LCD TV and there's a world of difference between the two in terms of how quickly each powers on and how fast one channel goes to the next after inputting the channel number on the respective remotes. The Sony is lightening fast compared to the Sanyo. I have a Phillips LCD in a bedroom that takes a long time as well, like the Sanyo. Personally I think you get speed with either the LED (over the LCD) and/or it's related to the quality and associated price you've paid.
