Hello... Fried devices on the y sus will usually blow the fuse on the y sus. That would explain no fizz. I hope this helps...

Eror code 12-22 then 53-54 in sony pfm-500a3we

Dear sir,

Code 53-54 means 2 fans on the behind of your Sony are not working.
This could effect the code 12/22.

Hint :

First fix the 2 fans.
If they're working , see if the code 12/22 has gone too.

If all the fans are working .... all 5x codes are gone !!!
If the code 12/22 is still present ..... the Sony turns on and off again and again.

In this case it's NOT the power supply unit !!!!
But you need to replace the X-SUS & Y-SUS print-boards inside your plasmascreen.
Located on te main printboard on the left and th eright side.
Replacements will cost arround the € 150,00/$ 100,00 for both boards.

Dis-connect the cables from the boards and un-screw the boards.
Replace the boards and re-connect the cablas and screws.

Problem for code 12/22 has being solved !!!!

No picture on my Toshiba 42HP66 plasma tv.

I too have this problem with no help from hh Gregg, where I bought the tv, and no help from Toshiba. I resorted to calling the BBB and complaining about the defective workmanship. I took the tv, which is less than 2 years old, apart and found the y-sus board, behind the y-sus board is a foam rubber spacer to seperate the circut board from the backside of the screen. I think this pad is designed to prevent heat buildup in the y-sus board. The pad itself is held on by glue and that glue melted causing the y-sus board to short out. I noticed this after finding a tacky substance behind the board. The heat from the plasma screen melted this and also the pad itself. Toshiba claims no resposibility because the tv was out of warranty. Thanks Toshiba.

Dan, The they are actually called Z sus and Y sus boards.. They are the 2 boards that are on the direct right and direct left of the panal at the connections. You can find the replacement boards on ebay pretty cheap.. However most of the time all it is is a blown cap. Worst case its a blown fet, but if your good with a meter, you can find the problem in about 5min and replace the defective components and be back on your feet for less than $10. This is all high voltage stuff, so somtimes components fail due to mass production and toleranace.

This is a very common problem with model. This problem is your Z sus Board. NOT your power supply, or Y sus board. There is a pair of Diode that goes bad. Your only solution is to change your Z sus Board. Part Number 6871QZH036B average cost $237.00
