The purpose of this thread is to clarify the ordering information needed to replace the capacitors in a TiVo HD or HD XL. Step 1: Figure out which model you have. This thread is covering the models TCD652160 and TCD658000. If you have a Series 3 OLED model (TCD 648250 or TCD648250B), then see this post for ordering information: http://www.tivocommunity.com/tivo-vb/showthread.php?p=9131293#post9131293 Step 2: Verify that your power supply is made by 3Y Power and has this part number: TiVoPN: SPWR-00011-000 RevB0. The part list in this post is specific to this supply. Pictures of this power supply are in this post: http://www.tivocommunity.com/tivo-vb/showthread.php?p=9628362#post9628362 Step 3: Make sure that you can do the work. Capacitors are polarized and must be installed correctly. The trick to soldering is to apply the minimum heat necessary to accomplish the task and enough to get the job done. (In other words try not to burn up your new devices). A video is posted here: http://www.tivocommunity.com/tivo-vb/showthread.php?p=8758939#post8758939 Step 4: Determine what you want to order. You can opt to change out the caps as they die, or do them all at once. Since the most expensive capacitor located at C120 is not a part under stress (in other words, a part with a longer life), you may only want to replace it if it is showing signs of failure. Step 5: Order your parts. Here's a list that I used from DigiKey. Code: QTY PART NUMBER DESCRIPTION LOCATION 1 1189-1197-ND CAP ALUM 470UF 200V 20% RADIAL C120 1 493-1896-ND CAP ALUM 47UF 50V 20% RADIAL C220 1 493-5362-1-ND CAP ALUM 10UF 25V 20% RADIAL C227 1 493-5369-1-ND CAP ALUM 2.2UF 50V 20% RADIAL C306 2 P12354-ND CAP ALUM 1000UF 10V 20% RADIAL C403,C503 1 P12376-ND CAP ALUM 470UF 16V 20% RADIAL C702 5 493-6967-ND CAP ALUM 2200UF 10V 20% RADIAL C402,C407,C501,C502,C504 1 P12366-ND CAP ALUM 1000UF 16V 20% RADIAL C701 Grand Total: $12.49 + tax + shipping ~$17 in total. Note, that there are multiple parts which may suffice as replacements, so my list may differ from others. I looked at other part lists posted on this forum and found issues with the specifications of the chosen parts. We want low ESR parts and high ripple currents. We need the ripple current equal to or higher than the original parts. Secondly, I favored parts that were in stock! Lastly, I didn't worry too much about package size since there is plenty of room. In case you need to substitute a part, here's the original part list and specifications. Code: QTY VENDOR & TYPE DESCRIPTION Ripple Imp LOCATION 1 CAPXON KF Series 470UF 200V ? ?
