I have replaced the lamp in my Toshiba model 52HMX84 and still have no picture. Could it be a tube?

Have you checked the switch on the lamp housing has to push the switch so it can be switched on. sometimes the case does not hit it.

I want to clean inside the screen & picture tube lamps but do not know how to open tv my tv is toshiba 57h81, picture is little dusty

just take out all screws, use compressed air, be careful, etc, screw back on. some models require u to remove the speakers grill or something by pulling them off to reveal the screws
here these pics may help you a lot (scroll down a little, and refresh if u see no pics, some guy named pittdog1 posted them)

I believe the blue lamp in my 57H81 is going bad.

You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips.
Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.

Convergence ICs - Toshiba 57h81

they send the instalation instructions with the ICs , which tells you what tools you would need and exactly how to replace them. yes both Ics should be repalced together as they work together to control the 3rd color. yes STK392-110 are the correct ICs for your model.

Toshiba 62HM195 needs a new light engine

This is a DLP type TV and if you mean the lamp, that is not a bad price however:
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy. Some models are real bulb hogs though. Look them up on the net (include the word complaint or repair) before you buy, or you might be sorry. Many class action lawsuits out there - even against some of the name brand makers.
Hope ya fix it!
