Question about Toshiba 52HMX84 52" Rear Projection HDTV-Ready Television

4 Answers

Toshiba 52HMX84 Sound no picture.

Upon turning on the TV it will buzz and the picture will not come on but you can hear the sound. I have gone through 3 bulbs in the last 3 yrs so I checked the bulb and it is still intact. Any suggestions as to a fix? I have put alot of monet into this TV and am getting fed up.

It's not a 1k Resistor but a 10k...it's the resistor R3 on the Circuit Board Part Number RPB-4434ZA (P/N: 23122468). If you don' replace the resistor you will keep burning your lamp. If you decide to replace the resistor by yourself...you should take the time to look at all the on the back of the board. This Board is made by the company Rubicon Corporation for Toshiba and it's a issue on the Toshiba DLP TV (62-52HMX84). If you don't wanna do the job yourself..bring your TV to a repair and give him the part number of the board and ask him to replace the board for you. If the price is higher than $350.00 go somewhere else...He try to fu....^&*%*%&%.

    my is 62HM84.
    right before Xmas, it's dead. so call dealer for service. today dealer quotes $390 to replace this RPB-4434ZA, and have to wait 1.5 months to deliver PCBA to Taiwan [where I live].
    so if replace the R3 resistor 1k or 10k can solve this problem, it will be great.
    any photo to show me where that R3 resistor is?
    I aint a technician....

Having the same problem with my 62HM84.

Found R3 on the 4434ZA board open. It's a 1K resistor.

Should I replace it with the same value ? I saw some post saying to change the value of it .

Tks for your help/..

I have replaced bulb and had the buzzing found the 10 k ohm restor and replaced the ristor still will not work did look at back of board it looks good do u have any more suggestions

Posted on Nov 17, 2008

On the circuit board that feed the 120v to the lamp...you should see a spark and it's the resistor 1K that you have to replace.

If you give me your email address...I will send some pictures to help you...my tv is all apart right now and my friend just found the problem.

Was working fine last night ,went to turn it on and you can hear a buzzing by where you plug in your jacks a bee,or high pitch sound.tv has no picture or sound.only sound you hear is this buzzing



Sounds like your power supply is causing the problem. Unplug the TV wait 10 minutes, look in the back for a red button (circuit breaker) push it in. If this does not work you have a low voltage power supply fault.

TV turns on, hear sound but no picture. Bulb isn't coming on. TV goes off after about 2-3 minutes. Bulb was just replaced 5 months ago.


Need the model number of the set and also if any lights on the TV come on or blink when the picture goes out or not.

Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...


It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.

No picture and blinking light consistently


Do you hear clicking or like wanting to turn on? it could be the ballast which is the board that powers the lamp .Do you hear buzzing ,whirling or like a high pitch sound? If you do it could be an issue with the color wheel.If you don't hear any of that and tv is between 1-2 yrs then most likely it's the lamp that needs to be replaced.Your Original lamp is Osram and last 4000-5000 hrs, get the Philips which will last 2-4 yrs 6000-8000 hrs.God bless you!

I had the black & white dots on my 46" HLS4676S..Replaced the DMD chip..Plugged it in and the indicator lights then said I had a bad bulb...Installed a new bulb and the same thing happened. Turns...


Make sure you have firmly seated the new Lamp. The next step is to go to the rear of the set and put your ear next to the Lamp Door while turning "ON" the tv with your tv remote.
You should hear a short buzzing sound. That is the Ballast "Exciter" firing up to light the Lamp. If you do not hear this buzzing then you probably have a bad Ballast. Ballast part# is BP47-00037A

Picture is gone! :*(


the picture tube (what makes the TV picture work) has blown out. Just call you nearest tv reapair shop and purchase a new one. (these are kind of expensive!)

(Also, if it's fifteen years old, i think it's time to get a new T.V. hint. hint.)
